Velocidex

An authenticated attacker can spoof another GUI user's identity by sending their request with the custom header \"Grpc-Metadata-USER\". This can lead to an account takeover attack from a user with low privileges to administrator.

Rapid7 Velociraptor MSI Installer versions below 0.73.3 suffer from a vulnerability whereby it creates the installation directory with WRITE_DACL permission to the BUILTIN\\Users group. This allows local users who are not administrators to grant themselves the Full Control…

Velociraptor allows multi-tenant deployments named "Orgs". By default Velociraptor, uses the ROOT org, but users can create child orgs for other tenants within the same deployment. Users can have different permissions in each org. To manage Orgs, Velociraptor usually examines…

When Velociraptor is configured to use an OIDC IdP for authentication, it uses the email claim as a username. However, some IdP allow users to change the email claim without verification. Some IdPs do not set the "email_verified" claim and do not actually verify the email. This…

Velociraptor's VQL has a query() plugin which allows running a VQL query in a different org or user context. To be able to run as a different user, the calling user needs to have the IMPERSONATE permission (usually only given to administrators). Velociraptor versions prior to…

Velociraptor allows scheduling new collections via VQL queries in notebooks. For a user to schedule a new collection, they require the COLLECT_CLIENT permission. However, this is not enforced when the user can run a VQL query which resets the authorization provider. This allows…

The NewNotebook API does not sufficiently sanitize its parameters allowing an authenticated user with NOTEBOOK_EDIT permission to write the notebook record outside the org's data store directory. The file written must have an extension of ".json.db" but can otherwise overwrite…

Velocidex WinPmem versions below 4.1 suffer from an Out of Bounds Write vulnerability. By using an IO Control, a user space program can trick the driver into writing a 0 into any chosen memory location. In conjunction with information leakage from the WinPmem driver, attackers…

The Velociraptor gRPC API has a VFSGetBuffer endpoint which allows reading files from the datastore. To prevent users from reading sensitive files or accessing other orgs, the requested path is prefix checked against a list of denied prefixes. This prefix check can be bypassed…

A YAML injection vulnerability exists in the Windows.Collectors.Remapping artifact of Rapid7 Velociraptor before version 0.76.6. The hostname field in client_info.json inside a collection ZIP is inserted into a YAML template via Go's text/template without escaping. An attacker…

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…

The hunt_delete() VQL function allows deleting hunts.  Velociraptor misapplied the permission check requiring only COLLECT_CLIENT (usually assigned to the "investigator" role) instead of the "DELETE_RESULTS" permission (usually only assigned to "administrators").

Any authenticated Velociraptor user — including one holding only the readerrole — can terminate the entire server process with a single request, by calling SetPassword with a username that does not exist.

When Microsoft Excel imports a CSV file, it executes cells beginning with certain characters as formulas, giving such CSV files arbitrary execution.  Velociraptor fails to sanitize such cells when exporting to CSV from various places such as the GUI, offline collector or data…

Velociraptor's NTFS parsing library mishandles several out of bound and memory exhaustion bugs which may be triggered by maliciously crafted NTFS images. Typically Velociraptor's NTFS parser is used on live NTFS filesystems, limiting the opportunity of attackers corrupting the…

Velocidex WinPmem versions 4.1 and below suffer from an Improper Input Validation vulnerability whereby an attacker with admin access can trigger a BSOD with a parallel thread changing the memory’s access right under the control of the user-mode application. This is due to…

A cross-site scripting (XSS) issue in generating a collection report made it possible for malicious clients to inject JavaScript code into the static HTML file. This issue was resolved in Velociraptor 0.6.5-2.

On MacOS and Linux, it may be possible to perform a symlink attack by replacing this predictable file name with a symlink to another file and have the Velociraptor client overwrite the other file. This issue was resolved in Velociraptor 0.6.5-2.

Due to a bug in the handling of the communication between the client and server, it was possible for one client, already registered with their own client ID, to send messages to the server claiming to come from another client ID. This issue was resolved in Velociraptor 0.6.5-2.

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…
