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.
CVE-2008-2639
Score elevated to 9.0 because EPSS predicts 86% probability of exploitation within the next 30 days (top 0.6% of all CVEs). Confidence: see factors.
- High exploitation likelihood — EPSS 78%
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
