Rapid7: >> Velociraptor >> 0.74.5 Security Vulnerabilities
An authorization bypass (CWE-639) in the GetUserRoles gRPC API endpoint in Velocidex Velociraptor below version 0.76.5 allows any authenticated low-privilege user to retrieve the complete ACL policy (roles and permissions) for any user across all organizations by supplying targeted Name and Org parameters via a network request.

An off-by-one error (CWE-193) in the ConsumeUnit16Array and ConsumeUnit64Array functions in Velocidex Velociraptor before version 0.76.5 on Windows and Linux allows a local attacker to cause a Denial of Service (DoS) via a process crash by providing a specially crafted .evtx file to the parse_evtx VQL plugin.

Velociraptor versions prior to 0.76.3 contain a vulnerability in the query() plugin which allows access to all orgs with the user's current ACL token. This allows an authenticated GUI user with access in one org, to use the query() plugin, in a notebook cell, to run VQL queries on other orgs which they may not have access to. The user's permissions in the other org are
the same as the permissions they have in the org containing the notebook.

Rapid7 Velociraptor versions prior to 0.76.2 contain an improper input validation vulnerability in the client monitoring message handler on the Velociraptor server (primarily Linux) that allows an authenticated remote attacker to write to arbitrary internal server queues via a crafted monitoring message with a malicious queue name. The server handler that receives client monitoring messages does not sufficiently validate the queue name supplied by the client, allowing a rogue client to write arbitrary messages to privileged internal queues. This may lead to remote code execution on the Velociraptor server. Rapid7 Hosted Velociraptor instances are not affected by this vulnerability.

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.
