"The CrushFTP application installed on the remote host is missing a
vendor-supplied patch. It is, therefore, affected by a sandbox escape
vulnerability. VFS Sandbox Escape in CrushFTP in all versions before 10.7.1
and 11.1.0 on all platforms allows remote attackers with low privileges to
read files from the filesystem outside of VFS Sandbox.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
