Off-by-one Error

CVE-2023-28709

High
7.5/10

Summary

The fix for CVE-2023-24998 was incomplete for Apache Tomcat. 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. This vulnerability affects Apache Tomcat versions 11.0.0-M2 through 11.0.0-M4, 10.1.5 through 10.1.7, 9.0.71 through 9.0.73, and 8.5.85 through 8.5.87.
