CVE-2009-2901: The autodeployment process in Apache Tomcat 5.5.0 through 5.5.28 and 6.0.0 through 6.0.20, when autoDeploy...

Security readout for executives and security teams

This is an old Apache Tomcat autodeploy flaw. If undeployment fails, leftover application files may be redeployed and reachable without the intended authentication controls. The main concern is legacy Tomcat systems still running affected versions with autoDeploy enabled. Likely exposure is legacy, self-managed Tomcat 5.5 or 6.0 deployments using autoDeploy. Internet-facing administrative or application hosts raise urgency. Modern supported Tomcat branches are not identified as affected in the provided sources. Treat as a legacy exposure cleanup item unless affected Tomcat is internet-facing or supports sensitive applications. Prioritize discovery and upgrade because the vulnerable versions are long out of support and may carry additional unpatched risks. Mitigation focus: Inventory Tomcat versions and identify 5.5.0-5.5.28 or 6.0.0-6.0.20.; Upgrade to a vendor-supported Tomcat release or vendor-patched package.; Review Apache and operating-system vendor advisories for exact fixed package versions..
