CVE-2011-1567: Multiple stack-based buffer overflows in IGSSdataServer.exe 9.00.00.11063 and earlier in 7-Technologies Int...

Security readout for executives and security teams

This CVE affects the IGSS SCADA data server described in the CVE record. A remote attacker could crash the service and may be able to run code by sending crafted requests to TCP port 12401. For operational technology environments, the main business concern is process visibility or control disruption if vulnerable systems are reachable. Exposure is most likely where 7-Technologies IGSS installations run IGSSdataServer.exe 9.00.00.11063 or earlier and allow network access to TCP/12401. Internet exposure or broad IT-to-OT reachability would materially raise urgency. Prioritize review if IGSS supports live industrial operations or if TCP/12401 is reachable outside a tightly controlled OT segment. The sources do not prove active exploitation, but public exploit information and possible code execution make unmanaged exposure unacceptable. Mitigation focus: Identify IGSS systems running IGSSdataServer.exe 9.00.00.11063 or earlier.; Restrict TCP/12401 to trusted OT management paths only.; Check vendor and US-CERT ICS guidance for patches or supported upgrades..
