"According to its self-reported version number, the instance of Apache
Tomcat listening on the remote host is 5.0.x equal to or prior to
5.0.30 or 5.5.x prior to 5.5.23. It is, therefore, affected by an HTTP
request smuggling vulnerability.

Requests containing multiple 'content-length' headers are not rejected
as invalid. This error can allow web-cache poisoning, cross-site
scripting attacks and information disclosure.

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