"The version of Tomcat installed on the remote Windows host is prior to 7.0.94. It is, therefore, affected by a remote
code execution vulnerability due to a bug in the way the JRE passes command line arguments to Windows. An 
unauthenticated, remote attacker can exploit this to execute arbitrary commands. 
Additionally, it is affected by a cross-site (XSS) scripting vulnerability as the SSI printenv command echoes user
provided data without proper escaping.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
