CVE-2023-45204

Code execution via IGS parser type confusion

Published Oct 10, 2023 · Updated Sep 18, 2024

Type confusion in Siemens Tecnomatix Plant Simulation 2201 before 2201.0009 and 2302 before 2302.0003 allows remote attackers to execute code. The IGS parser fails to validate user-supplied data before interpreting objects as incompatible types, enabling code execution in the current process. Exploitation requires a user to visit a malicious page or open a malicious file, and the code inherits the current process's privileges.
