Code execution via malformed PAR file parsing
Published May 14, 2024 · Updated Aug 2, 2024
Heap-based buffer overflow in Siemens Solid Edge before V224.0 Update 2 allows context-dependent attackers to execute code via a crafted PAR file. The PAR parser writes beyond an allocated heap buffer while processing malformed file data; Siemens has not disclosed the specific routine or field. Exploitation requires a user to open the attacker-supplied file, and resulting code runs with the privileges of the Solid Edge process.

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=0 <v224.0
- Affected versionversion=0 <V224.0 Update 2
