Technical description

An incorrect permission check in the admin backend in gvfs before version 1.39.4 was found that allows reading and modify arbitrary files by privileged users without asking for password when no authentication agent is running. This vulnerability can be exploited by malicious programs running under privileges of users belonging to the wheel group to further escalate its privileges by modifying system files without user's knowledge. Successful exploitation requires uncommon system configuration.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
