CVE-2024-38879Public exploitNetwork attack vector

Unauthenticated application access via exposed AJP service

Published Aug 2, 2024 · Updated Nov 3, 2025

Authentication bypass in Siemens Omnivise T3000 8.2 SP3, 8.2 SP4, and Application Server 9.2 allows remote attackers to access its web application. The Application Server exposes Tomcat's AJP connector on TCP port 8009, letting proxied requests bypass the port 8080 IP allowlist. Unauthenticated network access to the Application Server is sufficient to reach otherwise restricted web applications, including RemoteDiagnosticView.
