CVE-2022-29801Network attack vector

Server file disclosure via external entity resolution

Published May 10, 2022 · Updated Aug 3, 2024

XML external entity injection in Siemens Teamcenter 12.4 before 12.4.0.13 and 13.0 before 13.0.0.9 allows attackers to read server files. The affected XML parser resolves external entity references in crafted XML against resources on the application server filesystem; Siemens has not disclosed the specific parser or request handler. Network reachability and user interaction are required, and the bounded consequence is disclosure of files readable by the Teamcenter server process.
