🛡️ Sentinel: [HIGH] Fix Web UI CLI Command Execution Vulnerability#93SlasshyOverhere wants to merge 1 commit into
Conversation
🚨 Severity: HIGH 💡 Vulnerability: The Web UI's `/api/cli/run` endpoint allowed execution of interactive, non-web, or destructive CLI commands (like `vault2fa`, `sync`, `totp`, etc.). This could lead to a severe security risk as the interactive shell prompts are bypassed or data could be overwritten without intended constraints. 🎯 Impact: Attackers or malicious scripts (via XSRF/CSRF, or a compromised browser) could trigger arbitrary internal commands that alter critical vault state, overwrite configs, or start interactive tasks that cause hangs or unwanted behavior. 🔧 Fix: Added all interactive and dangerous commands (`vault2fa`, `totp`, `sync`, `duress`, `autolock`, `settings`, `theme`, `update`, `desktop`) to the `BLOCKED_WEB_CLI_COMMANDS` Set in `src/webui/server.ts` to explicitly block them from execution over HTTP endpoints. ✅ Verification: Ran `pnpm test` and `pnpm lint` to ensure everything works properly and the change hasn't broken existing functionality.

Blocklist is still bypassable via CLI aliases.
At Line 50, the new blocked commands omit known aliases; at Lines 533-536, enforcement is exact-match on the first token.
2fa-setup, vault-2fa, 2fa, and panic can still reach blocked handlers (vault2fa/totp/duress) through /api/cli/run.

runCliCommand blocks the delete command, but the CLI exposes delete with an alias rm (see src/index.ts). As a result, /api/cli/run can still delete entries by calling rm (e.g. rm --force ...), so the security fix is incomplete. Add rm (and any other destructive aliases) to BLOCKED_WEB_CLI_COMMANDS, or change the check to block based on Commander-resolved command name rather than the raw first token.

pnpm-lock.yaml is being added, but the repo’s CI and scripts use npm (npm ci, npm run build/lint/test) and the canonical lockfile in the repository is package-lock.json. Adding a pnpm lockfile without switching the toolchain will cause churn/confusion and can desync dependency resolution. Please remove pnpm-lock.yaml from this PR (or, if the intent is to migrate to pnpm, update CI/scripts/documentation and remove package-lock.json in a dedicated PR).
