Summary
CODESYS: Vulnerability in CODESYS Development System and CODESYS Scripting
Notes
Impact: Please consult CODESYS Security Advisory 2023-09 for more details.
Remediation: Update CODESYS Development System to version 3.5.17.0 . Update CODESYS Scripting to version 4.1.0.0 . This version can be downloaded and installed directly with the CODESYS Installer. A CODESYS DevelopmentSystem version of 3.5.17.0 is required. Alternatively, you can visit the CODESYS update area for more information on how to obtain the softwareupdate.
Summary: 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.
