Apache Tomcat 7.0.x < 7.0.23 Hash Collision DoS

According to its self-reported version number, the instance of Apache Tomcat 7.x listening on the remote host is prior to 7.0.23. It is, therefore, affected by a denial of service vulnerability.

Large numbers of crafted form parameters can cause excessive CPU consumption due to hash collisions.

Note that Nessus Network Monitor has not tested for this issue but has instead relied only on the application’s self-reported version number.
