CVE-2021-33711Network attack vector

Unauthenticated path disclosure via verbose error messages

Published Jul 13, 2021 · Updated Aug 3, 2024

Information disclosure in Siemens Teamcenter Active Workspace allows remote attackers to read full paths through verbose error messages. In the V4 branch before 4.3.9, V5.0 branch before 5.0.7, and V5.1 branch before 5.1.4, the web application returns errors containing sensitive server-side details instead of suppressing them. No authentication or user interaction is required; the disclosure reveals filesystem layout but does not directly alter data or interrupt service.
