Summary

CODESYS Control V3 runtime systems are affected by several security vulnerabilities in the communication server implementations for the CODESYS protocol. These may be exploited by authenticated attackers.

Details

Impact
The CODESYS Control runtime system enables embedded or PC-based devices to be a programmable industrial controller. Such products contain communication servers for the CODESYS protocol to enable communication with clients like the CODESYS Development System. For details of the vulnerabilities in the server implementations of CmpApp, CmpAppBP, CmpAppForce see vulnerability descriptions.

Mitigation
To exploit these vulnerabilities, a successful login to the affected product is required. The online user management therefore protects from exploiting these security vulnerabilities.

CODESYS GmbH strongly recommends using the online user management. This not only prevents an attacker from sending malicious requests or downloading virulent code, but also suppresses starting, stopping, debugging or other actions on a known working application that could potentially disrupt a machine or system. As of version 3.5.17.0, the online user management is enforced by default.

Remediation
Update the following products to version 3.5.19.20.

- CODESYS Control RTE (SL)
- CODESYS Control RTE (for Beckhoff CX) SL
- CODESYS Control Win (SL)
- CODESYS Control Runtime System Toolkit
- CODESYS Safety SIL2 Runtime Toolkit
- CODESYS Safety SIL2 PSP
- CODESYS HMI (SL)
- CODESYS Development System V3

Update the following products to version to 4.10.0.0. This version is scheduled for October 2023.

- CODESYS Control for BeagleBone SL
- CODESYS Control for emPC-A/iMX6 SL
- CODESYS Control for IOT2000 SL
- CODESYS Control for Linux SL
- CODESYS Control for PFC100 SL
- CODESYS Control for PFC200 SL
- CODESYS Control for PLCnext SL
- CODESYS Control for Raspberry Pi SL
- CODESYS Control for WAGO Touch Panels 600 SL

The CODESYS Development System and the products available as CODESYS add-ons can be downloaded and installed directly with the CODESYS Installer or be downloaded from the CODESYS Store.
Alternatively, as well as for all other products, you will find further information on obtaining the software update in the CODESYS Update area.
