Name of the Vulnerable Software and Affected Versions Anchore Engine version 0.7.0

Description A specially crafted container image manifest can trigger a shell escape flaw in the anchore engine analyzer service during an image analysis process. This can be executed by an authenticated user via a valid API request to anchore engine, or if an already added image that anchore is monitoring has its manifest altered to exploit the same flaw. A successful attack can execute commands in the analyzer environment with the same permissions as the user that anchore engine is run as, including access to the credentials that Engine uses to access its own database and the running engine analyzer service environment.

Recommendations For Anchore Engine version 0.7.0, update to version 0.7.1 to fix the issue. As a temporary workaround, consider restricting access to the analyzer service environment to minimize the risk of exploitation. Avoid running Engine directly or explicitly setting the user to 'root' to prevent elevated access.
