A vulnerability has been identified in Tecnomatix Plant Simulation (All versions < V16.0.5).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A vulnerability has been identified in Tecnomatix Plant Simulation (All versions < V16.0.5). The PlantSimCore.dll library lacks proper validation of user-supplied data when parsing SPP files. This could result in a stack based buffer overflow, a different vulnerability than CVE-2021-27396. An attacker could leverage this vulnerability to execute code in the context of the current process.
