Advisory Details

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of ABB Panel Builder 800. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the handling of the TargetAmsNetId and AmsNetId parameters of the ABB bebhoffadseth OPC Driver. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of an administrator.
