Information disclosure via PAR file buffer over-read
Published Aug 10, 2021 · Updated Aug 3, 2024
Out-of-bounds read in Siemens JT2Go and Teamcenter Visualization before 13.2.0.2 allows remote attackers to disclose process data. The plmxmlAdapterSE70.dll parser fails to validate user-controlled PAR data and reads beyond the end of an allocated buffer. Exploitation requires a user to open a malicious file or visit a malicious page, and the disclosed memory can aid a separate code-execution exploit.
