"According to its self-reported version number, the instance of Apache
Tomcat 7.0 listening on the remote host is prior to 7.0.32. It is,
therefore, affected by a security bypass vulnerability due to an error
in the file 'filters/CsrfPreventionFilter.java' that allows cross-site
request forgery (XSRF) attacks to bypass the filtering. This allows
access to protected resources without a session identifier.

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