Remote code execution via unsanitized beh job fields
Published May 17, 2023 · Updated Feb 13, 2025
Command injection in the beh backend in OpenPrinting cups-filters 2.0rc1 and earlier allows remote authenticated users to execute code. The backend builds a shell command from unsanitized job user and title fields and passes it to system(), allowing shell metacharacters to alter execution. Exploitation requires a network-accessible printer queue configured with beh; injected commands run with the print server's service privileges.
