Information disclosure via malformed JT file
Published Sep 28, 2021 · Updated Aug 4, 2024
Out-of-bounds read in Siemens NX before 1984 and Solid Edge before SE2021MP8 allows context-dependent attackers to disclose process memory. The JT-file parser fails to validate user-controlled data before reading beyond the end of an allocated buffer. Exploitation requires a user to open crafted JT content; the resulting read exposes memory from the current process without modifying data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
