CVE-2002-0935: Apache Tomcat DoS Via Requests Including Null Characters

April 30, 2022 (updated February 12, 2024)

Apache Tomcat 4.0.3, and possibly other versions before 4.1.3 beta, allows remote attackers to cause a denial of service (resource exhaustion) via a large number of requests to the server with null characters, which causes the working threads to hang.
