CVE-2011-1919: Multiple stack-based buffer overflows in GE Intelligent Platforms Proficy Applications before 4.4.1 SIM 101...

Security readout for executives and security teams

This CVE affects older GE Intelligent Platforms Proficy Applications used in industrial environments. A remote attacker could send crafted TCP traffic that crashes key Proficy services and may allow arbitrary code execution. Business urgency depends on whether these legacy Proficy components remain installed or reachable on operational networks. Exposure is likely limited to organizations still running the affected GE Proficy Server Manager, Server Gateway, Remote Data Service, or License Manager versions. Risk increases if those TCP services are reachable from enterprise networks, vendor remote access paths, or untrusted industrial network segments. Prioritize this for OT environments where affected Proficy services are still in use. The main business risk is disruption of industrial application services, with a possible code execution concern. If systems are legacy and hard to patch, require a documented exposure review and compensating network controls. Mitigation focus: Identify Proficy installations older than 4.4.1 SIM 101 or 5.0 SIM 43.; Apply vendor-supported updates to fixed SIM levels or later where available.; Restrict network access to the named Proficy services to trusted hosts only..
