--------- Begin Update A Part 1 of 1 --------

On August 26, 2011, ICS-CERT became aware of publicly available exploit code targeting a vulnerability in Sunway Force Control SCADA Version 6.1. The vulnerability results from inadequate bounds checking, which could allow execution of arbitrary code.

Initial ICS-CERT analysis of this public exploit indicates that the exploit is likely targeting a previously disclosed and patched vulnerability that was coordinated by ICS-CERT and security researcher Dillon Beresford, as reported in ICS-CERT Advisory ICSA-11-167-01. ICS-CERT has reached out to Sunway, the author of the exploit code, and to Mr. Beresford in order to confirm this analysis.

Concerned customers using affected versions of Sunway Force Control are encouraged to follow the mitigation  recommendations provided in ICSA-11-167-01.

ICS-CERT will provide additional information as it becomes available.
