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
Delta Electronics DIAEnergie (All versions prior to 1.8.02.004) has a blind SQL injection vulnerability that exists in DIAE_eccoefficientHandler.ashx. This allows an attacker to inject arbitrary SQL queries, retrieve and modify database contents, and execute system commands.

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 confidence

Delta Electronics DIAEnergie contains a blind SQL injection vulnerability in the DIAE_eccoefficientHandler.ashx component. This allows unauthenticated attackers to inject arbitrary SQL queries, potentially leading to full database compromise and OS command execution via the database layer.

MitigationUpdate DIAEnergie to version 1.8.02.004 or later to obtain the vendor patch. As a compensating control, implement input validation and consider deploying a WAF to filter malicious SQL injection payloads until the patch can be applied.

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. Locate DIAEnergie installation directory
    Search the system for directories containing 'DIAEnergie' or check common installation paths such as C:\Program Files\Delta or C:\inetpub\wwwroot\ for DIAEnergie web application folders.
    Affected if DIAEnergie is found installed on the system.
  2. Determine installed DIAEnergie version
    Inspect version information in the application files. Check the DIAEnergie executable, DLL files in the bin folder, or the assembly version metadata. Look for a version file or right-click the main application DLL to view Properties > Details.
    Affected if The installed version is lower than 1.8.02.004.
  3. Identify vulnerable component DIAE_eccoefficientHandler.ashx
    Locate the web application root directory for DIAEnergie and search for the file DIAE_eccoefficientHandler.ashx within the application structure, typically under the web root or a handlers subfolder.
    Affected if The file DIAE_eccoefficientHandler.ashx exists in the DIAEnergie web application.
  4. Verify application is network accessible
    Check if the DIAEnergie web application is exposed to network access by reviewing IIS or other web server bindings, firewall rules, and URL accessibility from external or non-localhost addresses.
    Affected if The DIAEnergie web interface is accessible from the network without proper authentication controls.

The environment is affected if DIAEnergie is installed with a version lower than 1.8.02.004 and the DIAE_eccoefficientHandler.ashx component is present and network-accessible.
