The remote web server can be manipulated into disclosing confidential data.
The remote host is running a version of Tomcat server lower than 6.0.16. This version of Tomcat is vulnerable to a flaw in the way that it handles exceptions. According to the vendor, if an exception occurs during the processing of parameters, the parameters may be used in future requests to disclose potentially confidential data.
Upgrade or patch according to vendor recommendations.
