Description of the vulnerability

The Apache Tomcat product offers a web service.

HTTP error pages may be customized. However, when the page content is provided by a static document instead of a servlet output, Tomcat allows to tamper with this source document.

An attacker can therefore trigger an HTTP error in Apache Tomcat, in order to corrupt the error page documents.
