CVE-2003-0045: Jakarta Tomcat before 3.3.1a on certain Windows systems may allow remote attackers to cause a denial of ser...

Security readout for executives and security teams

This is a legacy Jakarta Tomcat denial-of-service issue. On some Windows systems, a specially named JSP request could hang Tomcat threads and consume resources, potentially making the service unavailable. The sources do not indicate data theft, code execution, or active exploitation. Exposure is most likely in legacy environments still running Jakarta Tomcat earlier than 3.3.1a on Windows. Modern Tomcat deployments are unlikely to be affected unless they preserve very old unsupported versions. Treat this as a legacy availability risk. Prioritize remediation if old Windows-based Tomcat services are internet-facing or support business-critical applications. Otherwise, fold it into legacy platform retirement work. Mitigation focus: Inventory Windows hosts running legacy Jakarta Tomcat.; Upgrade Tomcat versions earlier than 3.3.1a per Apache release guidance.; Retire unsupported Tomcat 3.x deployments where possible..
