Security Posture — CRITICAL (Active Issue — Ticket #32378)

Classification: CONFIDENTIAL/Security. Full detail in:

• clients/glaztech/reports/2026-06-03-pci-cardholder-data-finding.md
• clients/glaztech/reports/2026-06-03-website-security-assessment.md

A full read-only security assessment of the Glaztech e-commerce web application and SQL backend was performed 2026-06-03. Overall risk: CRITICAL. Key findings (no card numbers or passwords are reproduced here):

C0 (TOP CRITICAL) — Website connects to GTI-INV-SQL as sysadmin

This is the single most dangerous finding. The public website at D:\web\glaztech_4 logs into the SQL server GTI-INV-SQL (192.168.8.62,3436) using SQL login tom — a named SQL login (SQL auth, created 2018, NOT the built-in sa) that is a member of the sysadmin server role (also securityadmin, dbcreator, db_owner). The password is embedded in the site's Web.config on the internet-facing server.

That same SQL instance (GTI-INV-SQL) is shared with GTIware (Tom's internal PSA) and hosts 46 databases: all offices' glaz_prod* + *_archive, PDF stores, qqest (TimeForce payroll), gti_samsara, mas_gti (Sage 100), and system DBs.

Because a SQL injection executes as the connecting login, the website's quo() SQLi flaw executes with full sysadmin rights across the entire instance. Cross-database reach was confirmed live: from a single injectable page on the Tucson connection, other offices' cc_file tables were read (glaz_prod_phx = 141 rows, glaz_prod_den = 190, glaz_prod_elp = 179).

Attack chain: (1) guess one website customer login (no lockout, username = account number, passwords as short as 3 chars, plaintext) → (2) hit an injectable payment page → (3) inject as sysadmin → total control of GTI-INV-SQL. As sysadmin an attacker can: steal every stored card PAN+CVV and password; DROP/encrypt all 46 databases (every office, all archives); commit fraud; enable xp_cmdshell → OS-level code execution on the SQL server → network pivot into the GTI/Glaztech environment.

One guessed website login + the SQLi = full theft, destruction, or ransom of the entire GTIware database server.

Required remediation — do this FIRST:

1. Pull the tom sysadmin login from the website. Give the site a dedicated least-privilege login scoped only to the tables/views/procs it needs, with no access to GTIware databases (no cc_file, no other offices, no archives).
2. Separate the website's data from GTIware. The internet-facing app must not share a SQL instance with the internal PSA's cardholder data.
3. Stop storing cards on-prem — call the processor's API/hosted vault directly (no card data lands on Glaztech systems), or at minimum tokenize (store a token, never the PAN). CVV must never be stored — PCI Req 3.2, no exception.
4. Fix the SQLi (parameterize all queries, remove quo()); add login lockout/rate-limiting.

Cardholder Data — PCI-DSS Violations (Req 3.2 + 3.4)

Storage attribution (IMPORTANT): The website stores NO cards. The website's .aspx/.vb files have zero cc_file/save_cc_data/gt_auto_process references; the quick-pay pages even carry a disclaimer that no card info is saved. The plaintext cards are written by GTIware — Tom's internal PSA (glaztech_utilities_2020.dll + gt_auto_process_2020.dll, compiled libs in the site Bin but not called by the site). Recent cc_file rows are stamped with staff usernames (Victoria, Bryce, Diana) and notes like "RUN CARD WHEN REQUESTED" — a back-office card-on-file workflow. The website is the access vector (C0), not the storer.

• cc_file (~780 saved cards): Full PAN stored in plaintext in every per-office database (glaz_prod, glaz_prod_phx, glaz_prod_slc, glaz_prod_elp, glaz_prod_den, glaz_prod_alb, glaz_prod_boi, glaz_prod_brl, glaz_prod_shp, glaz_prod_corp). Zero encrypted rows. cc_file.cc_code retains CVV/CID (50/54 rows in tuc; mirrors expected in all offices). CVV retention is a PCI Req 3.2 violation — indefensible; no exception even if encrypted.
• cof_payments_header (historical payments): Phoenix alone: 14,496 rows, 11,794 plaintext PANs. Tuc: 2,245 rows, ~367 plaintext + ~597 formatted. Years of transaction history with recoverable card numbers.
• Why cards are stored: Card-on-file invoice auto-pay. i_get_cc_on_file_invoices joins invoice × cc_file; gt_auto_process_2020.dll reads stored PANs and bills them via CyberSource. get_cc_data is SELECT * FROM cc_file (returns full PAN+CVV; IDOR-shaped on @acctno). Stale copies in Old_bin/Old_code\Bin. Feature can be preserved by migrating to the chosen processor's token vault — store a token reference instead of the raw PAN.
• Containment: Exposure is contained to the GTIware card-on-file tables (cc_file, cof_payments_header) in the 15 custom web-app databases on GTI-INV-SQL (192.168.8.62). The Sage 100 ERP DB (mas_gti) stores no cardholder data — its native CC module is disabled (SY_Company.CreditCardEnable=N, AR_CustomerCreditCard=0 rows; tokenization columns exist in the schema but are unused). Sage is not a cardholder-data location. Database backups also contain plaintext PANs — cleanup must address backups, not just live data.
• Processor reality (verified 2026-06-03): despite a belief that processing moved to "Payrilla/Paya," the website is still on CyberSource/PNC (no Payrilla anywhere in site code/config) and still writing plaintext cards daily (cc_file last write tuc 2026-06-03 14:15, phx 10:19; live CC-WebPayment-PNC txns today). Sage's CC module is off. Payrilla, if used, is a separate channel not visible in either system and not connected to the website — the website exposure is unchanged. Anomaly: cc_file absent in the corp DB though present earlier 2026-06-03 — needs a look.

Authentication — Plaintext Passwords

• web_security table: ~9,000+ plaintext customer passwords (corp 6,017 + tuc 3,012 confirmed, other offices expected); 0 hash-like values; lengths 3–19 chars; no complexity enforcement.
• Auth stored proc get_web_accesslevel: WHERE acct_no=@username AND web_password=@passwd — direct plaintext comparison.
• Employee "forgot password" flow emails the user their existing plaintext password — possible only with reversible/plaintext storage.
• No account lockout, no rate-limiting; username = customer account number (guessable).

SQL Injection — quo() Helper

Function quo(stext) As String
    Return "'" + stext + "'"  ' wraps in quotes, does NOT escape embedded quotes
End Function

Used to build concatenated dynamic SQL in payment pages (ach.aspx.vb, quick-pay-ach.aspx.vb, quick-pay-pnc.aspx.vb, quick-pay.aspx.vb, order-detail*). 59 concatenated SQL statements identified (~10 joining user input). The login path itself is parameterized (sproc) and not injectable; 948 parameterized calls elsewhere. Any input containing ' breaks out and allows injection; because the site connects as sysadmin, injection = full instance compromise (see C0).

Other Critical/High Findings

Finding	Severity
Reflected XSS: gt_errorpage.aspx — errmsg query param → lblerr.Text unencoded	High
debug="true" + customErrors=Off + exceptions echoed to users in URLs	High
Production server is also a dev workstation: VS Community 2015 + 2022, .NET 8 SDKs, MSBuild, IIS Express, full VB.NET source on disk	High
Remote-access sprawl: RealVNC Enterprise E4.2.8 (~2009, EoL), stale ScreenConnect v6.0.11622 (2018), Splashtop, Datto RMM+EDR, Syncro, GuruRMM (6+ agents)	High
Server listener accepts TLS 1.0 + 1.1 (SChannel Enabled=1)	High
Single shared SQL login (tom) with sysadmin rights; creds in Web.config in cleartext	High
No Secure/HttpOnly cookies; no session regeneration on login; session-fixation risk	High

Attack Chain Summary

Obtain a customer login (LOW difficulty — no lockout, guessable username = account number, plaintext passwords as short as 3 chars) → access payment pages → SQL inject with quo() → executes as sysadmin on GTI-INV-SQL → full read/write/DROP of all 46 databases, xp_cmdshell OS takeover, network pivot. Every compensating control (lockout, password hashing, PAN encryption, parameterized queries, least-privilege DB login) is absent; first failure is last failure.

Remediation Roadmap (Ticket #32378 — Waiting on Customer)

Now (days) — requires client sign-off:

1. Pull sysadmin login from the website: give the site a dedicated least-privilege login with no access to GTIware/card data (this alone cuts the blast radius of a breach from "total GTIware compromise" to "website DB only")
2. Purge stored CVV (cc_file.cc_code, backup-first — needs Tom/Steve explicit sign-off)
3. debug="false" + customErrors="On"; HTML-encode gt_errorpage.aspx; stop echoing exception text to users
4. Remove RealVNC 4.2.8 and stale ScreenConnect v6
5. Disable TLS 1.0/1.1 on the IIS/SChannel listener

Short term (weeks): 6. Hash all passwords (PBKDF2/bcrypt/Argon2); replace email-the-password flow with reset-token flow; force global reset 7. Parameterize all concatenated SQL in payment pages; delete quo() 8. Add Secure+HttpOnly cookies, session regeneration on login, login throttling/lockout 9. Migrate card-on-file to the chosen processor's token vault (CyberSource or new provider — confirm which flows actually route through "Payrilla"); purge/encrypt historical cc_number columns; address backups

Structural: 10. Separate dev from production; deploy precompiled; remove SDKs/IDE/source from prod host 11. Least-privilege SQL accounts per function; secret management for Web.config connection strings; TDE at rest; re-scope merchant PCI SAQ after remediation

Patterns & Known Issues

• Phishing via direct-to-M365 MX bypass: Two phishing campaigns in April 2026 succeeded because DNS had a secondary MX record (glaztech-com.mail.protection.outlook.com at priority 10) that bypassed MailProtector. Hardened: MX 10 removed, DMARC to p=reject, Enhanced Filtering for Connectors enabled. Do not re-add a secondary MX record.
• Inbound connector IP restriction: Do NOT restrict SenderIPAddresses on the "Inbound Spam Filter" connector — blocks legitimate calendar invites from external M365 tenants (learned from Dataforth incident). EFSkipIPs are set to MailProtector IPs instead.
• Do NOT set SCLMinusOne=true on connector: This would trust MailProtector's verdict for all inbound mail — too broad. Use targeted transport rules for specific senders instead.
• DMARC-rejecting vendor senders: With Enhanced Filtering enabled, EOP looks past MailProtector to the original sender's SPF/DKIM/DMARC. Vendors with p=reject domains (e.g., centurytel.net, eastexglass.com) get hard 550 5.7.509 NDR rejections. Fix: SCL=-1 transport rule scoped to the specific sender address or domain. Transport rules evaluate before DMARC enforcement in EOP.
• EXO transport rule name limit: 64-character maximum. Plan names accordingly.
• EXO REST API: Direct /TransportRule REST endpoints 404 in this tenant. Use InvokeCommand pattern: POST /adminapi/beta/{tenant}/InvokeCommand with {"CmdletInput": {"CmdletName": "New-TransportRule", "Parameters": {...}}}.
• Service accounts need audit before MFA rollout: Shoretel, mitel, Gti-FaxFinder, GTIMail, GTIQUOTE, CAS1944, clerk — all need SMTP/auth method confirmation before Security Defaults can be enabled.
• PDF preview broken (MOTW): Windows KB5066791/KB5066835 broke PDF preview on network shares via Mark of the Web. Fix scripts are ready in clients/glaztech/ — deployment is pending (as of 2026-03-30).
• clearcutglass.com DMARC history: Corena Spottsville (clearcutglass.com) emails to seastman and zulema were rejected. Temporary transport rule (SCL=-1) was set and removed on 2026-04-21. SPF ~all weakness noted to Team Logic IT (Jordan Fox, jfox@tlit60302.com); recommend they harden to -all and confirm DKIM.
• glassservices.com SPF broken: bossier@glassservices.com publishes v=spf1 -all — rejected by all mail providers. SCL=-1 rule covers this as a workaround. Steve should notify vendor to fix SPF.
• Client tone: ACG has managed GlazTech ~15 years. Steve Eastman is a trusted internal IT partner. Comments and communication should lead with what we know, state findings and actions taken, ask only one targeted question if needed — not open-ended discovery.
• Unlicensed accounts (pending Steve confirmation): Chauntelle@glaztech.com, Denouser1@glaztech.com, Gti-FaxFinder@glaztech.com.
• IIS apex binding — always add both http:80 and https:443 for the bare domain: The glaztech_new IIS site originally had only a www host-header binding. Apex (glaztech.com) returned 404 from HTTP.sys (not a 301 redirect, a real 404) because no binding matched. Fix: add http/IP:80:glaztech.com + https/IP:443:glaztech.com bindings reusing the existing SAN cert. When adding HTTP→HTTPS redirect via URL Rewrite, always include a negate condition on /.well-known/acme-challenge/ so Certify The Web (HTTP-01) LE renewals are not blocked.
• Legacy .NET + modern payment gateway TLS: .NET Framework 4.x apps on Windows Server 2019 do NOT automatically use TLS 1.2 unless the registry keys SchUseStrongCrypto=1 + SystemDefaultTlsVersions=1 are set under BOTH HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 AND HKLM\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319. Payment gateways (CyberSource, etc.) that drop TLS 1.0/1.1 will silently fail with "Could not create SSL/TLS secure channel" without this fix. App pool recycle required after registry change. Verify via the payments DB (look for fresh approvals), not just a TLS probe.
• MailProtector digest provisioning is per-mailbox on the MailProtector side: The SCL=-1 transport rule (Priority 4) ensures digest emails from noreply@azcomputerguru.com are not spam-filtered by EOP — but a mailbox that was never provisioned in MailProtector will never receive a digest regardless of EOP rules. Confirmed via message trace (shannon@glaztech.com: 629 digests sent to ~60 recipients over 10 days, 0 to Shannon). Fix is on the MailProtector partner portal — no Exchange change needed.
• Glaztech custom web app — stored card feature requires tokenization to remediate safely: Cards in cc_file are there for GTIware auto-pay via gt_auto_process_2020.dll. Deleting the PANs without a replacement breaks the auto-billing feature. The safe path is processor token vault migration (tokenize on write, replace stored PAN with token, update gt_auto_process to bill by token). Quick win: purge CVV (cc_code) immediately — this has no functional impact and is the fastest PCI Req 3.2 remediation.
• Glaztech SQL login (tom) + Web.config creds are NOT in the SOPS vault. Do not commit these credentials. If future automation needs SQL access, vault them first. This login has sysadmin rights — treat any use with corresponding care.
• Internet-facing website + internal PSA (GTIware) share one SQL instance; website connects as sysadmin → any website SQLi = full internal-DB compromise. The public website (WWW, 65.113.52.88) and GTIware (the internal card-on-file PSA) both use GTI-INV-SQL (192.168.8.62,3436). The web login tom is sysadmin. A SQL injection on the website executes as sysadmin against the entire 46-DB instance — cross-DB reads confirmed live. Public web apps must use least-privilege DB logins isolated from internal data. Internet-facing apps must never share a SQL instance with an internal PSA without strict permission partitioning.

Active Work

PDF Preview Fix (DEPLOYMENT-READY — pending execution)

Scripts in clients/glaztech/:

• Fix-PDFPreview-Glaztech-UPDATED.ps1 — updated remediation (recommended)
• Fix-PDFPreview-Glaztech.ps1 — original
• Deploy-PDFFix-BulkRemote.ps1 — bulk remote deployment
• GPO-Configuration-Guide.md — GPO method
• QUICK-REFERENCE.md — summary of all three methods

Deploy via Option A (ScreenConnect, individual), Option B (bulk remote via PS remoting), or Option C (GPO). Waiting on file server hostnames/IPs from Steve before bulk deploy.

MFA Rollout (Ticket #32186 — In Progress)

Waiting on Steve's reply to:

1. Service account auth methods (which use SMTP basic auth or password-only flows?)
2. Disposition of unlicensed accounts (Chauntelle, Denouser1, Gti-FaxFinder)
3. Licensing preference: Security Defaults (free, no exclusions) vs. per-user MFA (free, can exclude service accounts) vs. Conditional Access (requires Entra P1/Business Premium, ~$22/user/mo)

Do not enable Security Defaults until service accounts are confirmed safe.

MFA rollout plan: Phase 1 — user communication (install Authenticator); Phase 2 — enable enforcement; Phase 3 — follow-up stragglers; Phase 4 (future/P1) — Conditional Access with trusted IPs for office locations.

Website Security Remediation (Ticket #32378 — Waiting on Customer)

Security assessment complete 2026-06-03. Assessment and reports delivered to client (Steve/Tom). Tom replied 2026-06-03 confirming that the website stores no cards (correct); investigation of his reply surfaced C0 (sysadmin login). Reply posted on #32378 explaining the sysadmin+SQLi chain and the four required remediations. Ticket set to Waiting on Customer — Tom/Steve to remediate. ACG can execute quick wins (CVV purge, least-privilege login, debug-off) on client go-ahead.

Key actions queued but not yet executed (require client sign-off):

• Pull tom sysadmin login from the website → replace with least-privilege login that cannot see GTIware data (HIGHEST PRIORITY)
• Purge CVV from cc_file.cc_code (backup-first; needs explicit go-ahead from Tom)
• debug="false" + customErrors="On" — can apply quickly with low risk
• Remove RealVNC 4.2.8 and stale ScreenConnect v6
• Disable TLS 1.0/1.1 on IIS/SChannel listener

gtimail@glaztech.com Daily Digest Failure (Pending — review with Steve)

The "GTIMail No-Reply - Reject Inbound" transport rule (Priority 1) rejects all inbound mail to gtimail@glaztech.com, causing the daily MailProtector digest for that address to fail every day. This is a pre-existing rule and was not modified. Confirm with Steve Eastman whether gtimail@glaztech.com should receive MailProtector digests — if so, the rule needs an exception or the recipient needs to be removed from the MailProtector digest list.

shannon@glaztech.com — MailProtector Digest Not Received (Pending — MailProtector portal)

Message trace confirmed shannon@glaztech.com receives no MailProtector digests at all (0 of 629 digests over 10 days). This is a MailProtector-side provisioning issue — she is not provisioned/enabled in the MailProtector spam summary settings. No Exchange change needed. Fix: log into the MailProtector partner portal and enable the Spam Summary for shannon@glaztech.com. No vault credentials exist for MailProtector — manual portal access only.

Pending follow-ups

• Audit 38 OAuth consent grants (not done as of 2026-04-21)
• Confirm DKIM signing active in M365 for glaztech.com
• Monitor DMARC aggregate reports (rua=noreply@glaztech.com — should be a monitored mailbox or reporting service)
• Security awareness training for staff (multiple employees forwarded and replied to obvious phishing in April 2026)
• Review whether any user clicked phishing links (check sign-in logs for suspicious auth attempts post-April 17)
• Notify Steve: glassservices.com vendor needs to fix their SPF record (v=spf1 -all)
• Harts Glass original rejected emails need to be resent by sender — our SCL bypass is live but NDR'd messages do not auto-retry
• Consider creating retroactive Syncro ticket for 2026-05-28 SHVSALES email delivery work
• Monitor continued card payment success on WWW after 2026-06-03 TLS fix (verify web_payment_header for ongoing approvals)
• Tom code fallback (ServicePointManager.SecurityProtocol = Tls12 in app code) staged but not deployed — can apply if registry fix ever regresses
• Investigate corp DB cc_file "Invalid object name" anomaly (existed 2026-06-03 morning with 3 rows, then returned "Invalid object name" later same day — per-office DBs unaffected)
• Confirm with Tom/Payrilla which flows actually route through Payrilla, and whether a migration to tokenized card storage via the new provider is planned for the website

History Highlights

• [~15 years prior] Long-standing managed client.
• 2026-01-27 — PDF preview break caused by Windows MOTW update (KB5066791/KB5066835). Fix scripts created. Deployment pending.
• 2026-04-17 — Two phishing campaigns bypassed MailProtector via direct-to-M365 MX bypass. 32 messages purged across 8 users. Hardened: MX 10 removed, DMARC p=reject, Enhanced Filtering Connectors enabled. Remediation tool onboarded (admin consent, Exchange Admin role). Forensic evidence preserved in clients/glaztech/reports/.
• 2026-04-20 — Exchange transport rule created to allow clearcutglass.com mail (DMARC bypass, SCL=-1) while Team Logic IT fixed their DNS. Ticket #32176 created.
• 2026-04-21 — clearcutglass.com DNS fixed by Team Logic IT (Jordan Fox). Transport rule removed. External Global Admin (glaztechadmin from tomakkglass.com / Team Logic IT) removed from tenant. M365 security review surfaced: no MFA, 38 OAuth grants, unlicensed accounts, service account audit needed. Ticket #32186 opened for MFA implementation. Feedback: use expert-partner tone with Steve, not open-ended discovery questions.
• 2026-05-28 — SHVSALES@glaztech.com vendor email delivery failure. Root cause: vendors (centurytel.net, eastexglass.com) publish DMARC p=reject; Enhanced Filtering re-evaluates past MailProtector relay, producing 550 5.7.509 NDR. Fix: two SCL=-1 transport rules created (Priority 2: specific addresses for hartsglass, olemons, SSales, bossier; Priority 3: aaaglassinc.com domain). glassservices.com SPF broken (-all) — workaround only, vendor must fix.
• 2026-06-02 — MailProtector quarantine digest messages from noreply@azcomputerguru.com confirmed hitting FilteredAsSpam for some recipients (e.g., tshaw@glaztech.com). Transport rule created: "SCL Bypass - noreply@azcomputerguru.com (MailProtector digests)" at Priority 4 (From=noreply@azcomputerguru.com, SetSCL=-1). Message trace via Get-MessageTraceV2 also revealed gtimail@glaztech.com failing daily due to pre-existing Priority-1 reject rule — flagged for Steve review.
• 2026-06-03 (earlier) — Three tickets on web server WWW (192.168.8.72 / 65.113.52.88), all via GuruRMM. (1) Apex 404 emergency: glaztech.com returned 404 (IIS site glaztech_new had www-only binding); added apex http:80+https:443 bindings (cert SAN already covered apex), then added HTTP→HTTPS 301 URL Rewrite redirect with /.well-known/acme-challenge/ exclusion (Certify/LE HTTP-01 renewal safe). web.config.bak-20260603-090701 created. Ticket #32376 — Resolved, 1h remote. (2) CyberSource payment outage ("Could not create SSL/TLS secure channel"): CyberSource (PNC merchant processor) disabled TLS 1.0/1.1; .NET 4.x on Server 2019 defaulted to old TLS. Fix: SchUseStrongCrypto=1 + SystemDefaultTlsVersions=1 in both .NETFramework\v4.0.30319 hives + app pool glaztech_new recycle. Verified via payments DB (credit-card approval at 09:36 post-fix). Ticket #32377 — Resolved, 1.5h emergency remote. (3) Security assessment: read-only deep inspection of IIS config, VB.NET source, and SQL backend revealed CRITICAL posture. Sage 100 (mas_gti) confirmed NOT a cardholder-data location — CC module disabled (0 stored cards). Two reports created. Ticket #32378 opened. Billed 1h remote. Prepaid block: 26.5 → 22.25 hrs. Also: shannon@glaztech.com digest-not-received confirmed as MailProtector provisioning issue (not Exchange) — requires MailProtector partner-portal fix. Payrilla/CyberSource reconciliation: live system confirmed website is still on CyberSource/PNC with daily ongoing card writes.
• 2026-06-03 (late — ~19:32 PT) — Tom (GTIware dev) replied to #32378 clarifying that the website's online payment system stores no card data — he is correct. Investigation of Tom's reply surfaced the top critical finding (C0): the website connects to the shared SQL server GTI-INV-SQL (192.168.8.62,3436) as SQL login tom, a named SQL login that is a member of the sysadmin role (created 2018; password in Web.config). The instance hosts 46 databases shared between GTIware and the website. Because SQLi executes as the connecting login, the website's quo() injection = sysadmin over the entire GTI-INV-SQL instance; cross-database card-table reads confirmed live. Attribution corrected in both reports: the website is the access path (C0); GTIware (staff-operated) writes the cards. Sage CC module confirmed disabled (0 stored cards, not a CHD location). Both reports updated. Plain-English reply posted to Tom on #32378 (public+emailed, comment 417070212) explaining the sysadmin+SQLi chain and the four required fixes. Ticket set to Waiting on Customer.
