Vulnerability from variot
Heap-based buffer overflow in the Siemens WinCC Runtime Advanced Loader, as used in SIMATIC WinCC flexible Runtime and SIMATIC WinCC (TIA Portal) Runtime Advanced, allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a crafted packet to TCP port 2308. Siemens SIMATIC WinCC flexible and WinCC (TIA Portal) Runtime Advanced is a software package for virtualization. A security vulnerability exists in the implementation of Siemens SIMATIC WinCC, which can be exploited by malicious users to control the affected system. This vulnerability stems from an error in the runtime loader when parsing a received message, causing a heap buffer overflow through a specially crafted message sent to port 2308/TCP. ----------------------------------------------------------------------

DESCRIPTION: A vulnerability has been reported in Siemens SIMATIC WinCC, which can be exploited by malicious people to potentially compromise a vulnerable system.
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.
