DESCRIPTION:
A vulnerability has been reported in Siemens SIMATIC WinCC, which can
be exploited by malicious people to potentially compromise a
vulnerable system.
The vulnerability is caused due to an error in the runtime loader
when parsing received packets and can be exploited to cause a
heap-based buffer overflow via a specially crafted packet sent to
port 2308/TCP.
Successful exploitation may allow execution of arbitrary code, but
requires that "transfer" mode is enabled (disabled by default).
SOLUTION:
Disable "transfer" mode or restrict access to port 2308/TCP.
PROVIDED AND/OR DISCOVERED BY:
Billy Rios and Terry McCorkle via ICS-CERT.
