"The version of Tomcat installed on the remote host is prior to 11.0.0.M5. It is, therefore, affected by a vulnerability
as referenced in the fixed_in_apache_tomcat_11.0.0-m5_security-11 advisory. If non-default HTTP connector settings were
used such that the maxParameterCount could be reached using query string parameters and a request was submitted that
supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be
bypassed with the potential for a denial of service to occur.

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