A vulnerability was found in Citect CitectSCADA 6/7 (SCADA Software). It has been classified as very critical. Affected is an unknown code. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow in the ODBC server service in Citect CitectSCADA 6 and 7, and CitectFacilities 7, allows remote attackers to execute arbitrary code via a long string in the second application packet in a TCP session on port 20222.

The weakness was shared 06/16/2008 by Nicolas Economou (Basti) with CORE IMPACT Exploit Writers Team as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability is traded as CVE-2008-2639. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 12/30/2024).

A public exploit has been developed by Kevin Finisterre in Ruby and been published 3 months after the advisory. The exploit is shared for download at securityfocus.com. It is declared as highly functional.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 6205.

The vulnerability is also documented in the databases at X-Force (42992), Exploit-DB (6387), SecurityFocus (BID 29634†), SecurityTracker (ID 1020241†) and Vulnerability Center (SBV-29387†).
