Schneider Electric IGSS Heap-based Buffer Overflow Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Schneider Electric IGSS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of TCP traffic by the dc.exe process. 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 in the context of the user running IGSS.
