The remote web server is affected by a directory traversal vulnerability.
The version of Apache Tomcat running on the remote host is affected by a directory traversal vulnerability due to an issue with the UTF-8 charset implementation within the underlying JVM. An unauthenticated, remote attacker can exploit this, by encoding directory traversal sequences as UTF-8 in a request, to view arbitrary files on the remote host. Note that successful exploitation requires that a context be configured with 'allowLinking' set to 'true' and the connector with 'URIEncoding' set to 'UTF-8', neither of which is a default setting.
Upgrade to Tomcat 6.0.18 / 5.5.27 / 4.1.SVN or later.
