tag_summary = "Acritum Femitter Server is prone to a remote file-disclosure
vulnerability because it fails to properly sanitize user-
supplied input.

An attacker can exploit this vulnerability to view the source code of
the files in the context of the server process. This may aid in
further attacks.

Acritum Femitter Server 1.03 is affected; other versions may be
vulnerable as well.";
