The remote host is vulnerable to a directory traversal flaw.
The remote host is running the Apache Tomcat server. This version of Tomcat is vulnerable to a directory traversal flaw. An attacker exploiting this flaw would only need to be able to send a malformed request to the server. Successful exploitation would result in the attacker being able to read arbitrary files with the permission of the web server process. This can lead to disclosure of source code or confidential data.
Upgrade to version 5.5.23, 6.0.10 or higher.
