CVE-2014-0779: Schneider Electric StruxureWare SCADA Expert ClearSCADA Improper Restriction of Operations within the Bounds of a Memory Buffer

The PLC driver in ServerMain.exe in the Kepware KepServerEX 4 component in Schneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R2 build 71.4165, 2010 R2.1 build 71.4325, 2010 R3 build 72.4560, 2010 R3.1 build 72.4644, 2013 R1 build 73.4729, 2013 R1.1 build 73.4832, 2013 R1.1a build 73.4903, 2013 R1.2 build 73.4955, and 2013 R2 build 74.5094 allows remote attackers to cause a denial of service (application crash) via a crafted OPF file (aka project file).

Security readout for executives and security teams

This vulnerability affects older Schneider Electric ClearSCADA builds. A malicious project file could crash the server application, creating an operational disruption risk in SCADA environments. The provided sources do not show active exploitation or a confirmed patch version. Exposure is likely limited to organizations still running the listed 2010 or 2013 ClearSCADA builds and accepting or processing OPF project files, especially in OT networks where project files move between engineering workstations and servers. Treat this as a moderate legacy OT risk. It can disrupt SCADA availability, but the provided evidence supports denial of service only and does not show active exploitation. Prioritize if affected systems are still operational or receive external project files. Mitigation focus: Identify all ClearSCADA and SCADA Expert ClearSCADA versions and build numbers.; Check Schneider Electric and CISA guidance before applying upgrades or compensating controls.; Restrict import or handling of OPF project files from untrusted sources..
