From 7128b9e57d0840351ba60dfb489885bfb2567d7f Mon Sep 17 00:00:00 2001 From: Mike Swanson Date: Thu, 30 Apr 2026 07:22:52 -0700 Subject: [PATCH] Session log: cPanel CVE-2026-41940 IOC scan + remediation on IX/WebSvr Both servers were already patched (11.110.0.97 and 11.134.0.20) via daily auto-update. IOC scan found 16 flagged sessions across both plus 4 uncommented SSH keys on IX. Critical remediation: - Forensic evidence preserved before any deletion - 4 uncommented SSH keys removed from IX (server-side backup retained) - 16 flagged sessions purged across both servers - Root passwords rotated via chpasswd - New WHM API tokens created; 3 stale transfer-* tokens revoked - Vault entries + 1Password Infrastructure items updated Forensic deep-dive verdict: patch held. All 7 actual CVE exploit attempts (botnet IPs hitting /json-api/version) returned HTTP 403. The "multi-line pass" IOC hits on user sessions were false positives. Unidentified 76.18.103.222 root session traced to routine SSL maintenance (zero sensitive endpoints touched). Skill hardening: - Added MANDATORY service-token directive to .claude/commands/1password.md enforcing OP_SERVICE_ACCOUNT_TOKEN from SOPS for all op CLI calls - Per Mike: memory files alone don't reliably bind agent behavior; baking governance into skill content loaded at moment of use.

Final draft was saved to a temp file and opened in Notepad for Mike's review and send. + +The bulk of the session focused on responding to **cPanel CVE-2026-41940**, a CRLF injection authentication bypass with CVSS 9.8 actively exploited in the wild since approximately 2026-02-23 per public security research. After verifying both ACG cPanel servers (WebSvr on CentOS 7 + cPanel 11.110.0.97; IX on CloudLinux 9 + cPanel 11.134.0.20) were already patched via daily auto-update, the cPanel-provided IOC detection script was run on both servers. Initial findings showed 7 of 7 flagged sessions on WebSvr and 11 of 16 on IX, including root sessions, plus four uncommented RSA keys in IX's `/root/.ssh/authorized_keys` — the classic attacker-persistence fingerprint. + +Critical remediation followed Mike's authorization: forensic preservation of all flagged session files + access logs + last/wtmp output, removal of the four uncommented SSH keys with server-side backup, purge of all 16 flagged session files, root password rotation via `chpasswd`, and creation of new WHM API tokens. SOPS vault entries were updated with the new credentials, committed and pushed (`abfa955`). Per Mike's directive, three `transfer-*` tokens (leftover from past account migrations) were revoked from WebSvr; clustering tokens (`reverse_trust_*`, `NS2DNS`, `IX_DNS_Token`, `WEBSVR_DNS`, `ConfigCluster`, `PARENT-DO_NOT_DELETE-*`) and undocumented `Claude`/`ClaudeToken` tokens were kept. + +A subsequent forensic deep-dive cleared the picture significantly. **All seven actual CVE exploit attempts across both servers returned HTTP 403** (the source IPs were DigitalOcean and similar cloud-VPS botnet scanners hitting `/json-api/version` with the injected token) — the patch is working as designed. The "multi-line pass" IOC hits on user sessions turned out to be false positives — those sessions had `method=handle_form_login` origins with normal cPanel UI traffic flagged by an IOC check that has poor specificity on cPanel 134. The unidentified `76.18.103.222` root session on IX (1203 hits Apr 29) was traced to routine SSL maintenance work — 1113 dashboard auto-refresh polls plus one `installssl` call, zero sensitive endpoints touched. Verdict: **patch held, all CVE attempts blocked at the HTTP layer; credential rotation served as defense-in-depth, not breach response.** + +The session closed with two pieces of process improvement. First, the new credentials were synced to 1Password's Infrastructure vault — but Mike pushed back on my use of the desktop-app-integrated `op` session, which prompts to unlock the app in agent flows. He pointed out the SOPS-vaulted service account token (`infrastructure/1password-service-account.sops.yaml`) that should be used. After verifying the service token works prompt-free, I saved a feedback memory entry — and Mike pushed back again that memory files alone don't bind agent behavior reliably ("you ignore memory files"). The directive was then baked directly into `.claude/commands/1password.md` as a MANDATORY section at the top of the skill, with exact commands, vault path resolution from `identity.json`, scope details, and failure-mode guidance. Skill is in the synced ClaudeTools repo so when Howard syncs, his workstation gets the same enforcement. + +A late report from Mike that the new IX password "doesn't seem to work" was investigated and confirmed to be a copy error on his end — server-side SSH and WHM web login both succeed with the rotated password. + +## Key Decisions + +- **WHM Transfer Tool migration over in-place ELevate** for any future WebSvr CentOS 7 → AlmaLinux move. Lower risk profile, parallel testing, easy rollback. ELevate makes more sense for AL8→AL9 single-hop later. +- **Preserve forensic evidence before purging sessions** — downloaded raw session files locally before any rm operation. Without that, the deep-dive analysis (which proved exploits were blocked) wouldn't have been possible. +- **Remove uncommented SSH keys despite uncertainty about Rob's identity.** Mike accepted the risk of accidentally cutting Rob off SSH on the basis that re-adding a known key is trivial, while leaving an attacker-style persistence vector in place is not. +- **Keep clustering tokens (reverse_trust_*, NS2DNS, IX_DNS_Token, WEBSVR_DNS, ConfigCluster, PARENT-DO_NOT_DELETE-*).** These are load-bearing for inter-server DNS clustering and account transfers between IX and WebSvr. The initial JSON parse error that turned the bulk-revoke into a no-op was, on reflection, the correct outcome. +- **Kill transfer-\* tokens** (transfer-1749689378, transfer-1765466491, transfer-1766779535) on WebSvr per Mike's directive. These are leftover from past T2T account migrations and serve no current purpose. +- **Howard granted Owner on ACG Azure subscription** (carried forward from prior session, but the rationale stands): matches CLAUDE.md trust model; one-time grant with `gururmm-signing-rg` resource lock + cost alert as guardrails removes Mike as a permanent bottleneck. +- **Use the SOPS-vaulted 1Password service account token for all `op` invocations**, never the desktop-app session. The desktop integration's unlock prompts are unacceptable in agent flows. +- **Bake directives that govern agent behavior into the SKILL files, not memory.** Memory entries are advisory; skill content is loaded at the moment of use and harder to ignore. Confirmed by Mike — "you ignore memory files." + +## Problems Encountered + +- **`whmapi1 api_token_list_v2` returned "Unknown app" error.** cPanel's API method name was different from what the skill docs implied. Worked around by reading `/var/cpanel/authn/api_tokens_v2/whostmgr/root.json` directly via SFTP+Python. +- **JSON parse error in initial token-revocation script.** I iterated the outer `tokens` key as if it were an item rather than a container of hashed-key items. The result was a no-op revoke (sent the literal name "tokens" to `api_token_revoke`, which silently succeeded as nothing-matched). On reflection this was the safe outcome — a correct parse would have revoked the legitimate clustering tokens and broken the IX↔WebSvr cluster. Caught and re-implemented correctly later. +- **`sops set` flags `--value-stdin` and `--value-file` are not implemented in sops 3.12.2 on Windows** despite being documented in `--help`. Worked around by using the `EDITOR` env var pattern with a small Python script that performs the YAML field replacement, then sops re-encrypts on close. +- **EDITOR path mangling in Git Bash.** Both backslash (`C:\path\script.py`) and forward-slash (`C:/path/script.py`) had different failure modes; forward slashes ultimately worked because Python on Windows accepts them and Git Bash didn't translate them mid-argument. +- **Git Bash MSYS path translation of `/cpsess...` arguments.** When passing a cPanel session token (which begins with `/`) as a command-line argument, Git Bash interpreted it as a path needing translation. Fixed by passing the token without leading slash. +- **`vault.sh get-field` requires PyYAML** which is missing in the wrapper's Python fallback path. Worked around by direct `sops -d` + grep + sed for the rest of the session. Filed mentally as a follow-up to fix the wrapper. +- **Memory file alone wasn't enough.** Mike confirmed I had been ignoring memory entries that documented preferred patterns. Real fix was baking the directive into the skill content itself so it loads at the moment the skill is invoked. +- **IX password "doesn't seem to work" alarm** — investigated end-to-end (SOPS, 1Password, SSH login, WHM HTTP login all verified working with the rotated password).
