Descriptions

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.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of CODESYS Development System. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the LearnMoreAction function. The issue results from a missing integrity check on notification data. An attacker can leverage this vulnerability to execute code in the context of the current user.
