prior to 8.0.22.1262. It is, therefore, affected by a denial of service (DoS) vulnerability exists in a bundled 
component (Apache Tomcat) due to insufficient validation of user input. An unauthenticated, remote attacker can 
exploit this issue to impose a DoS condition on the application.  

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