Summary
CODESYS: Missing integrity check in CODESYS Development System
Notes
Summary: The Notification Center of the CODESYS Development System receives messages without ensuring that the message was not modified during transmission. This finally enables MITMs code execution when the user clicks the "Learn More" button.
Remediation: Update the CODESYS Development System to version 3.5.19.20. The CODESYS Development System can be downloaded and installed directly with the CODESYS Installer or be downloaded from the CODESYS Store. Alternatively, you will find further information on obtaining the software update in the CODESYS Update area
CVE-2023-3663

In CODESYS Development System versions from 3.5.11.20 and before 3.5.19.20 a missing integrity check might allow an unauthenticated remote attacker to manipulate the content of notifications received via HTTP by the CODESYS notification server.
