CVE-2015-1014
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA successful exploit of these vulnerabilities requires the local user to load a crafted DLL file in the system directory on servers running Schneider Electric OFS v3.5 with version v7.40 of SCADA Expert Vijeo Citect/CitectSCADA, OFS v3.5 with version v7.30 of Vijeo Citect/CitectSCADA, and OFS v3.5 with version v7.20 of Vijeo Citect/CitectSCADA.. If the application attempts to open that file, the application could crash or allow the attacker to execute arbitrary code. Schneider Electric recommends vulnerable users upgrade the OFS to V3.5 and install the latest service pack (SP 6 or newer) for their associated version.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a DLL hijacking vulnerability in Schneider Electric OFS (OPC Foundation Server) v3.5 when bundled with SCADA Expert Vijeo Citect/CitectSCADA versions 7.20, 7.30, and 7.40. A local authenticated user can place a malicious DLL in the system directory; when the application loads it, the application may crash or permit arbitrary code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed OFS versionLocate the OPC Factory Server installation directory (typically under the SCADA software folder) and check the version information of the OFS executable or DLL files, or query the Windows registry for the installed version under the appropriate Schneider Electric product keysAffected if The installed OFS version is exactly 3.5 and is bundled with Vijeo Citect/CitectSCADA versions 7.20, 7.30, or 7.40
-
Confirm bundled Vijeo Citect versionCheck the installed version of Vijeo Citect or CitectSCADA on the system by examining the program's version information in the installation directory or via Add/Remove ProgramsAffected if The system has Vijeo Citect/CitectSCADA version 7.20, 7.30, or 7.40 installed with OFS 3.5
-
Verify OFS service exists and runsOpen Windows Services console and locate the OPC Factory Server service, check its status and startup typeAffected if The OFS service is present and configured to run (the DLL would only be loaded when the service executes)
-
Assess DLL search order exposureExamine the OFS installation directory and system directories for weak permissions that would allow an authenticated user to write files, and identify which DLLs OFS attempts to load from the system directoryAffected if Authenticated users have write access to directories where OFS loads DLLs from, creating a hijacking opportunity
A system is affected if it runs OFS version 3.5 bundled with Vijeo Citect/CitectSCADA 7.20, 7.30, or 7.40, where an authenticated local user could place a malicious DLL in a location that OFS loads from.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSchneider Electric recommends upgrading OFS to V3.5 and installing the latest service pack (SP6 or newer) for the associated Vijeo Citect/CitectSCADA version.
