Lifecycle Timeline
3DescriptionCVE.org
Velociraptor contains a deadlock condition that may be triggered by authenticated users. The issue stems from a lock management bug in the user management module.
AnalysisAI
Authenticated users of Rapid7 Velociraptor can trigger a server-side deadlock in the platform's user-management module, hanging server operations and causing a denial of service (CVSS 6.5, AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Exploitation requires only a valid low-privileged account that can reach the user-management code path over the network - no user interaction, no elevated role, and no special configuration - but it offers no data read, modification, or code execution, so it cannot be used for initial access or lateral escalation. …
