Title
SOCFortress CoPilot: Authentication Bypass and Missing Authorization on Velociraptor Sigma Exclusion Rules (Detection Suppression)
Summary
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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
