Rapid7: >> Velociraptor >> 0.74 Security Vulnerabilities
Rapid7 Velociraptor versions before 0.75.6 contain a directory traversal issue on Linux servers that allows a rogue client to upload a file which is written outside the datastore directory. Velociraptor is normally only allowed to write in the datastore directory. The issue occurs due to insufficient sanitization of directory names which end with a ".", only encoding the final "." AS "%2E".
Although files can be written to incorrect locations, the containing directory must end with "%2E". This limits the impact of this vulnerability, and prevents it from overwriting critical files.

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).
