Apache Tomcat AJP denial of service

tomcat-ajp-dos (50928) The risk level is classified as MediumMedium Risk

Description:

Apache Tomcat is vulnerable to a denial of service, caused by the improper handling of header files by the Java AJP connector. By sending a specially-crafted HTTP header request, a remote attacker could exploit this vulnerability to block the mod_jk load balancer which temporarily blocks connectivity to the server.IBM3
