Apache Tomcat hash denial of service

apache-tomcat-hash-dos (72016) The risk level is classified as MediumMedium Risk

Description:

Apache Tomcat is vulnerable to a denial of service, caused by insufficient randomization of hash data structures. By sending multiple specially-crafted HTTP POST requests to an affected application containing conflicting hash key values, a remote attacker could exploit this vulnerability to cause the consumption of CPU resources.
