CVE-2022-37034Network attack vector

Unauthenticated service interruption via repeated large downloads

Published Feb 1, 2023 · Updated Mar 27, 2025

Denial of service in dotCMS 5.x through 22.06 allows remote attackers to exhaust Tomcat request threads through repeated TempResource calls. Each call makes the server download a large file, and repeated calls occupy the request-thread pool until it cannot process additional requests. Unauthenticated network access is sufficient, and the reported consequence is interruption of legitimate requests without data disclosure or modification.
