Summary

This vulnerability in Apache Tomcat is triggered by improper input validation for HTTP/2 requests. Specifically, when an HTTP/2 request exceeds configured header limits, the system fails to reset the associated stream immediately, leading to a possible Denial of Service. Users are advised to update to versions 11.0.0-M17, 10.1.19, 9.0.86, or 8.5.99 to mitigate this issue effectively.

Affected Version(s)

Apache Tomcat 11.0.0-M1 <= 11.0.0-M16

Apache Tomcat 10.1.0-M1 <= 10.1.18

Apache Tomcat 9.0.0-M1 <= 9.0.85

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
