A flaw was found in Apache Tomcat due to an incomplete fix for CVE-2023-24998, which aims to limit the uploaded request parts that can be bypassed in a request. This issue may allow an attacker to use a malicious upload or series of uploads to trigger a denial of service.

Description Patrick Del Bello 2023-05-26 15:18:22 UTC 
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 maxParameterCount could be reached using query string parameters and a request was       submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur.
