AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Cantata versions prior to 2.3.2

Description An issue was discovered in the cantata-mounter D-Bus service. The mount target path check in mpOk() function is insufficient, allowing a regular user to mount a CIFS filesystem anywhere by passing directory traversal sequences.

Recommendations For Cantata versions prior to 2.3.2, update to version 2.3.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of the mpOk() function in the cantata-mounter D-Bus service to minimize the risk of exploitation.
