tag_summary = "Xlight FTP Server is prone to multiple directory-traversal
vulnerabilities because it fails to sufficiently sanitize user-
supplied input.

Exploiting these issues may allow an attacker to obtain sensitive
information which could aid in further attacks.

Xlight FTP Server 3.5.5 is vulnerable; other versions may also
be affected.";
