Crayfish allows Remote Code Execution via Homarus Authorization header
### Impact Remote code execution may be possible in web-accessible installations of Homarus in certain configurations. ### Patches The issue has been patched in `islandora/crayfish:4.1.0` ### Workarounds The exploit requires making a request against the Homarus's `/convert` endpoint; therefore, the ability to exploit is much reduced if the microservice is not directly accessible from the Internet, so: Prevent general access from the Internet from hitting Homarus. Configure auth in Crayfish to be more strongly required, such that requests with `Authorization` headers that do not validate are rejected before the problematic CLI interpolation occurs. ### References - XBOW-024-071
