Name of the Vulnerable Software and Affected Versions Assemblyline versions prior to 4.6.1.dev138

Description The Assemblyline 4 Service Client interfaces with the API to fetch tasks and publish the result for a service in Assemblyline 4. The client accepts a SHA-256 value returned by the service server and uses it directly as a local file name. A malicious or compromised server can return a path-traversal payload, allowing it to write downloaded bytes to an arbitrary location on disk.

Recommendations Assemblyline versions prior to 4.6.1.dev138 should be upgraded to version 4.6.1.dev138.
