Detail
Vulnerability Note VU#222657RealFlex RealWin HMI service buffer overflowsOverviewRealFlex RealWin 1.06 HMI service (912/tcp) contains two stack buffer overflow vulnerabilities.I. DescriptionRealFlex RealWin is a SCADA server package for medium and small applications designed to control and monitor real-time applications. The RealWin application runs an HMI service on port 912/tcp. This service is vulnerable to two stack-based buffer overflows. One vulnerability is caused by the use of sprintf() in the SCPC_INITIALIZE() and SCPC_INITIALIZE_RF() functions. The second vulnerability is caused by the use of strcpy() in the SCPC_TXTEVENT() function.Further information is available in ICS_CERT Advisory ICSA-10-313-01

68812 | DATAC RealWin Multiple Packet Type Processing Overflow RealWin is prone to an overflow condition. The program fails to properly sanitize user-supplied input resulting in a stack-based buffer overflow. With a specially crafted 'SCPC_INITIALIZE', 'SCPC_INITIALIZE_RF' or 'SCPC_TXTEVENT' packet, a remote attacker can potentially execute arbitrary code. |
