Velociraptor
Monthly
Remote code execution in Rapid7 Velociraptor server (versions <0.76.2, primarily Linux) allows authenticated attackers to write arbitrary messages to privileged internal queues via crafted client monitoring messages with malicious queue names. Improper input validation in the server's client monitoring message handler fails to sanitize queue names supplied by rogue clients, enabling queue injection attacks that escalate to RCE. Affects self-hosted instances only; Rapid7 Hosted Velociraptor instances are not vulnerable. No public exploit identified at time of analysis.
Velociraptor allows collection of VQL queries packaged into Artifacts from endpoints. These artifacts can be used to do anything and usually run with elevated permissions. To limit access to some dangerous artifact, Velociraptor allows for those to require high permissions like EXECVE to launch. The Admin.Client.UpdateClientConfig is an artifact used to update the client's configuration. This artifact did not enforce an additional required permission, allowing users with COLLECT_CLIENT permissions (normally given by the "Investigator" role) to collect it from endpoints and update the configuration. This can lead to arbitrary command execution and endpoint takeover. To successfully exploit this vulnerability the user must already have access to collect artifacts from the endpoint (i.e. have the COLLECT_CLIENT given typically by the "Investigator' role).
