Code execution via WRL heap buffer overflow
Published Sep 12, 2023 · Updated Aug 2, 2024
Heap-based buffer overflow in Siemens JT2Go, Teamcenter Visualization, and Plant Simulation allows attackers to execute process-context code. The WRL parser copies user-supplied data into a heap buffer without validating its length, permitting an overwrite beyond the allocated region. Exploitation requires a user to visit a malicious page or open a crafted WRL file, after which attacker-controlled code runs with the current process's privileges.

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.
- Affected versionversion=All versions < V2201.0010
- Affected versionversion=All versions < V2302.0004
