Name of the Vulnerable Software and Affected Versions 3S CoDeSys version 3.4 SP4 Patch 2

Description The issue is related to an integer overflow in the GatewayService component, which can be exploited by remote attackers to execute arbitrary code. This is achieved by sending a packet with a large size value in the header, triggering a heap-based buffer overflow.

Recommendations For version 3.4 SP4 Patch 2, consider applying a patch or fix to address the integer overflow issue in the GatewayService component. As a temporary workaround, restrict access to the GatewayService component to minimize the risk of exploitation.
