Descriptions

In CODESYS Development System 3.5.9.0 to 3.5.17.0 and CODESYS Scripting 4.0.0.0 to 4.1.0.0 unsafe directory permissions would allow an attacker with local access to the workstation to place potentially harmful and disguised scripts that could be executed by legitimate users.

This vulnerability allows local attackers to escalate privileges on affected installations of CODESYS Development System. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the handling of python scripts. The issue results from the lack of resource separation between control spheres. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the Administrator.
