The version of Samba running on the remote host is 4.9.x prior to 4.9.13, 4.10.x prior to 4.10.3.8, or 4.11.x prior to 4.11.0rc3. It is, therefore, affected by security bypass vulnerability.
An unauthenticated attacker could use this flaw to escape the shared directory and access the contents of directories outside the share.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
