Automated Solutions OPC Server contains a heap corruption vulnerability in the Modbus/TCP Master OPC server.
Automated Solutions Modbus/TCP Master OPC Server contains a heap corruption vulnerability. The server is vulnerable to an attacker writing an arbitrary number of double words or DWORDs onto the heap.
For additional information see ICSA-10-322-02A.
Successful exploitation would likely not allow arbitrary code execution; however, an exploit could possibly corrupt the OPC server memory and cause a denial of service.
Thanks to Jeremy Brown for reporting this vulnerability to ICS-CERT.
