A vulnerability has been identified in Tecnomatix Plant Simulation V2201 (All versions < V2201.0008), Tecnomatix Plant Simulation V2302 (All versions < V2302.0002). The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted PAR file. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-21155)

Vendor and ecosystem advisories describing this.

SSA-764801SSA-764801: File Parsing Vulnerabilities in Tecnomatix Plant Simulation2023-07-11csaf · siemens_psirtDE
Siemens Tecnomatix Plant Simulation contains multiple vulnerabilities that could be triggered when the application reads PAR, SPP, STP and PRT files. If a user is tricked to open a malicious file using the affected application, this could lead to a crash, and potentially also to arbitrary code execution on the target host system. Siemens has released updates for the affected products and recommends to update to the latest versions.
