An issue was discovered in Schneider Electric Unity PRO prior to V11.1. Unity projects can be compiled as x86 instructions and loaded onto the PLC Simulator delivered with Unity PRO. These x86 instructions are subsequently executed directly by the simulator. A specially crafted patched Unity project file can make the simulator execute malicious code by redirecting the control flow of these instructions.

Vendor fix, mitigation, or workaround guidance, as published by each source.

No vendor fix yet; a mitigation is available.

MitigationUnity Procisa_csaf_ot
Schneider Electric recommends the following mitigation practices: Upgrade to Unity PRO Version 11.1. By default, it is not possible to launch this version of the simulator without any Unity PRO application associated. Exercise caution in selecting which project files are executed by the simulator. Do not trust files that come from unknown or untrusted sources. Use strong passwords to protect applications. It is not possible to load or to modify this application without being authenticated once the password protected application has been loaded onto the simulator.
