Name of the Vulnerable Software and Affected Versions Tecnomatix Plant Simulation versions prior to 16.0.5

Description A memory corruption condition can occur due to the lack of proper validation of user-supplied data when parsing SPP files in the PlantSimCore.dll library. This could allow an attacker to execute code in the context of the current process.

Recommendations For versions prior to 16.0.5, update to version 16.0.5 or later to resolve the issue. As a temporary workaround, consider restricting access to SPP files to minimize the risk of exploitation.
