Velociraptor GUI result set path bypass due to inadequate prefix denial checks in multi-tenant design

Short explanation

Velociraptor's GUI allows reading stacked result sets from child orgs due to inadequate prefix denial checks in its multi-tenant design. CVSS 4.9 (MEDIUM) severity. Patch status UNKNOWN. No fixed version published. Exploitation requires high privilege (PR:H).

Why does it matter?

This allows privilege escalation within multi-tenant environments, enabling unauthorized access to sensitive data from child organizations. Mitigation requires strict access control and immediate patching if available.

What should be done?

Apply vendor patch if available; otherwise, restrict GUI access to root org only and enforce strict access controls.

Note on uncertainty

The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.

Velociraptor, çok kirli tasarımındaki veri depolama dizininde, istenen yolu önceden reddetme listesine doğru kontrol etmemesi nedeniyle, kök örgütte okuma yetkisi olan bir kullanıcıya çocuk örgütlerin sonuç setlerine erişim izin verir.

Show the technical text from the sources

Velociraptor allows reading Stacked result sets from the GUI. Velociraptor's multi-tenant design stores sub orgs within the datastore directory. The path requested by the GUI is not correctly checked against the prefix deny list, allowing result sets to read from denied prefixes. In particular, a user with read access to the root org can access result sets from child orgs.

Confirm the affected product and version against the source evidence above.

Restrict access to internet-facing services and apply network segmentation.

Until a patch is confirmed, follow the vendor advisory; do not read an unknown status as “no patch”.

Monitor server logs and network endpoints for signs of anomalous execution.
