Description
In multiple Codesys products in multiple versions, after successful authentication as a user, specific crafted network communication requests with inconsistent content can cause the CmpApp component to read internally from an invalid address, potentially leading to a denial-of-service condition. This vulnerability is different to CVE-2023-37545, CVE-2023-37546, CVE-2023-37547, CVE-2023-37548 and CVE-2023-37549.
