Apache HTTP Server 413 error page cross-site scripting

apache-413error-xss (38800)

Medium Risk

Description:

Apache HTTP Server is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote attacker could embed malicious script within a HTTP method request containing an invalid length data value, which would be executed in the victim's Web browser within the security context of the hosting site, once the link is clicked and a "413 Request Entity Too Large" error page is returned. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
