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 · unedited

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 · moderate confidence

A denial of service vulnerability exists in the PLC driver of ServerMain.exe within ClearSCADA. The driver fails to properly validate a crafted OPF (project) file, causing the application to crash when the malformed file is processed. This is remotely exploitable without authentication.

MitigationRestrict network access to SCADA systems, implement strict input validation on OPF files before processing, and apply vendor patches when available. Consider network segmentation to limit exposure.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm ClearSCADA installation
    Locate ServerMain.exe on the system - typical paths include C:\Program Files\Aveva\ClearSCADA\ or C:\SCADA\ directories. Also check Windows Programs and Features for Aveva ClearSCADA.
    Affected if ServerMain.exe is present or ClearSCADA software is installed
  2. Identify installed version
    Check the version of ServerMain.exe by right-clicking the file and selecting Properties > Details, or query the installed programs list for 'ClearSCADA 2010' or 'ClearSCADA 2013'.
    Affected if Version is ClearSCADA 2010 or ClearSCADA 2013
  3. Verify PLC driver component
    Examine the ClearSCADA configuration or modules list within the ClearSCADA administration interface to confirm the PLC driver module is present and loaded.
    Affected if PLC driver module is enabled or loaded in ClearSCADA
  4. Check for OPF file processing capability
    Search for .OPF files in the ClearSCADA data directory or system, and verify if the system has the ability to import or process project files through ServerMain.exe.
    Affected if OPF file processing or import functionality is available in the installation

User is affected if ClearSCADA 2010 or 2013 is installed with the PLC driver enabled and OPF file processing capability present.
