___________________________________________________________________ Insomnia Security Vulnerability Advisory: ISVA-110427.1 ___________________________________________________________________ Name: IGSS ODBC Service Remote Overflow Vulnerability Released: 27 April 2011 Vendor Link: http://www.igss.com Affected Products: IGSS (Interactive Graphical SCADA System) v9 Original Advisory: http://www.insomniasec.com/advisories/ISVA-110427.1.htm Researcher: James Burton, Insomnia Security http://www.insomniasec.com ___________________________________________________________________ _______________ Description _______________ IGSS (Interactive Graphical SCADA System) is a complete automation software - a SCADA system for process control and supervision. It was developed by 7-Technologies and is the first world's first object orientated, mouse operated SCADA system. A remote stack overflow vulnerability exists in the IGSS ODBC service. No authentication is required to exploit this vulnerability. _______________ Details _______________ The ODBC service component of IGSS listens on port 20222/tcp by default. The application layer protocol runs over TCP and reads an initial packet that specifies the amount of data to follow. A second read then takes place and the data is copied into a variable length buffer. Next the data is parsed and during this process a buffer overflow occurs on the stack. At minimum this vulnerability leads to denial of service though remote code execution may be possible. _______________ Solution _______________ Download the latest version using the IGSS Update application found under the Information and Support menu of IGSS Master.
