CVE-2024-35303

Code execution via MODEL-file parser type confusion

Published Jun 11, 2024 · Updated Aug 2, 2024

Type confusion in Siemens Tecnomatix Plant Simulation before V2302.0012 and V2404.0001 allows attackers to execute code via a MODEL file. The MODEL-file parser treats crafted data as an incompatible type; Siemens has not disclosed the affected routine or conversion. Execution requires a user to open the file, and successful exploitation runs code in the current process or crashes the application.
