Security readout for executives and security teams
CVE-2015-3940 is a local privilege escalation issue in Schneider Electric Wonderware System Platform versions before 2014 R2 Patch 01. A local user could abuse unsafe DLL search behavior to run code with higher privileges. Business urgency depends on whether affected engineering or operations hosts still exist. Exposure is most likely on legacy Schneider Electric Wonderware System Platform deployments older than 2014 R2 Patch 01, especially shared engineering workstations or HMI-related hosts where local users can write files. Prioritize remediation where legacy Wonderware systems are used in production operations or shared administrator environments. This is not documented as internet-exploitable or actively exploited in the bundle, but local privilege escalation can weaken ICS workstation controls. Mitigation focus: Upgrade Wonderware System Platform to 2014 R2 Patch 01 or later.; Review Schneider bulletin LFSEC00000106 for vendor-specific remediation details.; Review ICS-CERT advisory ICSA-15-169-02 for operational guidance..
