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 wrapper script 'mount.cifs.wrapper' uses the shell to forward arguments to the actual mount.cifs binary, allowing the shell to evaluate wildcards, such as those in an injected string.

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 mount.cifs.wrapper script until a patch is available. Avoid using the mount.cifs binary with untrusted input to minimize the risk of exploitation.
