HTTP: Apache Tomcat maxParameterCount Denial of Service
This signature detects attempts to exploit a known vulnerability against Apache Tomcat maxParameterCount. A successful attack can result in a denial-of-service condition.
Extended Description
The fix for CVE-2023-24998 was incomplete for Apache Tomcat 11.0.0-M2 to 11.0.0-M4, 10.1.5 to 10.1.7, 9.0.71 to 9.0.73 and 8.5.85 to 8.5.87. If non-default HTTP connector settings were used such that the maxParameterCountcould be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parametersin the query string, the limit for uploaded request parts could bebypassed with the potential for a denial of service to occur.
