The CitectSCADA and CitectFacilities applications include ODBC server capabilities to provide remote SQL access to a relational database. For that purpose, an ODBC Server component is used to service requests from clients on TCP/IP networks. Requests are serviced over a TCP high-port in which the application layer protocol reads an initial packet that specifies the length of data and then a second packet of data, of the same length is then read. Once the data is read from the network, it is then copied to an internal buffer of fixed size allocated in the stack without previously verifying that the buffer is big enough to store all the read data.\\r\\n\\r\\nThe vulnerability is related to a lack of a proper length-checking on data read from the network. A specially crafted combination of length and data packets could be used to exploit the vulnerability allowing an un-authenticated attacker to execute arbitrary code on vulnerable systems.\\r\\n\\r\\nThe bug is a texbook example of classic simple stack-based buffer overflow vulnerabilities of the 1990s that can be exploited by overwriting the return address of the currently running thread.\\r\\n\\r\\nFixes and Workarounds:\\r\\n\\r\\nUser organizations should deploy the vendor patch, which is available upon request at http://www.citect.com/ or disable the vulnerable service (ODBC server) if it is not needed in their particular installation.\",\"evaluatorSolution\":\"Citect will provide a patch upon request to mitigate this vulnerability.  Please see the following press release for more information:\\r\\n\\r\\nhttp://www.citect.com/documents/news_and_media/pr-citect-address-security.pdf\\r\\n\\r\\nFor further information on properly securing SCADA systems, please see the following whitepaper published by Citect:\\r\\n\\r\\nhttp://www.citect.com/documents/whitepapers/scada-security-whitepaper.pdf\",\"evaluatorImpact\":\"The access complexity for this vulnerability is set at High due to the fact that exploiting this vulnerability requires the SCADA system to be connected to the internet and the client needs to be using ODBC technology.  SCADA systems are not typically installed to connect to the internet for security purposes.  While the vendor acknowledges that this vulnerability exists and will provide a patch upon request, they point out that this can be easily mitigated by ensuring SCADA systems (not limited to Citect products) are not connected to the internet.\\r\\n\"}}"
