VERY IMPORTANT

A critical path equivalence vulnerability in Apache Tomcat, CVE-2025-24813, allows unauthenticated attackers to execute arbitrary code on vulnerable servers under specific conditions. The vulnerability affects Tomcat versions 11.0.0-M1 to 11.0.2, 10.1.0-M1 to 10.1.34, 9.0.0.M1 to 9.0.98, and certain 8.5.x versions. Exploitation requires specific server configurations and involves sending malicious PUT and GET requests. Six malicious IP addresses have been identified attempting to exploit this vulnerability, targeting systems in the US, Japan, Mexico, South Korea, and Australia. Multiple proof-of-concept exploits have been published, increasing the likelihood of ongoing exploitation attempts. Users are advised to upgrade to patched versions or implement network-level controls to restrict access to the Tomcat server.
