SOCFortress CoPilot Authentication Bypass and Missing Authorization Vulnerability

Short explanation

Prior to version 0.1.77, SOCFortress CoPilot suffers from authentication bypass and missing authorization vulnerabilities in Velociraptor Sigma exclusion management endpoints. This flaw allows attackers to suppress detections platform-wide and enables low-privileged users to modify rules.

Why does it matter?

Endpoints lacking proper credential validation allow attackers to entirely suppress security alerts and detection rules, creating critical blind spots in enterprise security monitoring.

What should be done?

  • Upgrade SOCFortress CoPilot to version 0.1.77 or later
  • Follow the vendor advisory

Show the technical text from the sources

SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.77, the Velociraptor Sigma exclusion-management endpoints in `backend/app/incidents/routes/incident_alert.py` omit role and tenant authorization, and `POST /api/incidents/alerts/create/velo-sigma/exclusion` does not validate credentials. Its `return_username_for_logging` dependency in `backend/app/auth/utils.py` calls `decode_token`, which returns ordinary Invalid token or Expired signature strings on failure, and the dependency passes these strings through instead of rejecting the request. A Bearer header is required, but an arbitrary invalid, expired or forged value can create a suppression rule without a valid account. The collection GET at /create/velo-sigma/exclusion lists exclusions; the read, update and delete routes under `/create/velo-sigma/exclusion/{exclusion_id}`, and the `/velo-sigma/exclusion/{exclusion_id}/toggle` route, use `get_current_user` without role checks, permitting any authenticated `customer_user` to manage every exclusion. In `backend/app/incidents/services/velo_sigma.py`, `process_sigma_alert` calls `check_exclusions` and drops matching enabled alerts before incident creation. A null `customer_code` applies a rule across all tenants. Attackers can suppress detections platform-wide through channel, title or field matching, while low-privilege accounts can enumerate detection-tuning data and modify, disable or delete legitimate exclusions. This issue is fixed in version 0.1.77.
