From b4a710d20767e120e4b47a5950101f4bdd1a2009 Mon Sep 17 00:00:00 2001 From: jpetree331 Date: Sun, 29 Mar 2026 17:19:12 -0400 Subject: [PATCH] verify: E-1c configurable timeouts and path sanitization verified All 6 timeout values configurable via DB settings. Fallback to defaults confirmed for fresh installs. Path traversal defense verified (403 + logging). Fixed hardcoded duration references in timeout.go log output. 163 tests pass, no regressions.

A symlink at `binaries/evil -> /etc` would pass the prefix check. + +`TestDownloadsRejectsSymlinkEscape` tests the concept by manually calling `filepath.EvalSymlinks()` then checking the resolved path against the prefix — this proves a symlink-resolved path outside the dir is detected. However, the **handler itself does not call `EvalSymlinks`**, so the test demonstrates awareness but not actual handler behavior. + +Residual risk: LOW. Requires both DB compromise (to set `BinaryPath`) and filesystem access (to create symlink). Documented as DEV-038. + +### 4c. Allowed Directory Config — PASS +- `REDFLAG_BINARY_STORAGE_PATH` env var read in `config.go` line 168 +- Default: `./binaries` +- Empty protection: `filepath.Abs("")` returns CWD (not empty), so `allowedDir` is never empty string. The `HasPrefix` check would then allow all files under CWD — wider than intended but not a bypass. The fallback on line 193-194 (`if allowedDir == ""`) is defensive code that cannot actually trigger. + +### 4d. Error Log Format — PASS +``` +[ERROR] [server] [downloads] path_traversal_attempt package_id=%s resolved_path=%s allowed_dir=%s +``` +No emoji. ETHOS compliant. + +### 4e. Security Tests — PASS +- `TestDownloadsRejectsPathTraversal`: Uses `../../../etc/passwd`, confirms prefix check rejects. ✓ +- `TestDownloadsAcceptsSafePath`: Creates temp dir, file inside, confirms prefix check accepts. ✓ +- `TestDownloadsRejectsSymlinkEscape`: Creates symlink, resolves via EvalSymlinks, confirms outside-dir path is caught. ✓ (tests concept, not handler — see 4b) + +--- + +## Part 5: Settings Integration Check + +### 5a. UI Display — KNOWN LIMITATION +`SecuritySettings.tsx` hardcodes category sections (`command_signing`, `update_signing`, `nonce_validation`, `machine_binding`, `signature_verification`). The new `operational` category is NOT displayed in the UI. Settings are accessible via the API (`GET /security/settings`) but not visible in the admin dashboard. + +### 5b. Runtime Updates — KNOWN LIMITATION +The server reads timeout values **once at startup** and stores them in local variables. Changing a setting via `PUT /security/settings/operational/offline_threshold_minutes` updates the DB but the running goroutines continue using the boot-time values. **A server restart is required for changes to take effect.** + +### 5c. Validation — KNOWN LIMITATION +`ValidateSetting()` has no cases for `operational.*` keys. The switch/case falls through to `return nil` (no validation). The `validation_rules` JSONB field stores `{"min": 30, "max": 3600}` but nothing in the code reads or enforces it. An admin could set `offline_threshold_minutes` to `0` or `9999` via the API. However, `getOperationalSetting()` would reject `0` (the `f > 0` check), and `9999` minutes (6.9 days) would be allowed but operationally problematic. + +--- + +## Part 6: ETHOS Compliance + +### 6a.
