The remote web server can be manipulated to disclose confidential data.
The remote host is running a version of Tomcat server less than 6.0.15. This version of Tomcat is vulnerable to a flaw in the way that it parses WEBDAV 'lock' requests. Specifically, if the lock request references an external file, Tomcat will retrieve the file. This could lead to information disclosure of potentially confidential data. An attacker exploiting this flaw would need to have the ability to authenticate to the Tomcat server.
Upgrade to version 6.0.15 or higher.
