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 exists in DIAE_privgrpHandler.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 (versions prior to 1.8.02.004) contains a blind SQL injection vulnerability in the DIAE_privgrpHandler.ashx handler. An unauthenticated attacker can inject arbitrary SQL queries through this endpoint, potentially allowing database content retrieval/modification and OS command execution via database features.

MitigationUpgrade to DIAEnergie version 1.8.02.004 or later. If immediate patching is not feasible, implement web application firewall rules to block SQL injection attempts against the affected handler and restrict network access to the management interface.

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. Identify DIAEnergie installation
    Search for the DIAEnergie web application files on the system. Common installation paths include C:\inetpub\wwwroot\DIAEnergie or similar directories under the web server root. Look for the presence of the DIAE_privgrpHandler.ashx file.
    Affected if The handler file DIAE_privgrpHandler.ashx exists on the server and the installed version is prior to 1.8.02.004
  2. Determine installed version
    Locate version information in the application files. Check for a version.txt, about page, or version metadata in thebin folder DLLs. The version may also be visible in the application footer or login page.
    Affected if The version displayed is less than 1.8.02.004 (for example, 1.8.01.000, 1.7.x, or earlier)
  3. Check handler accessibility
    Attempt to access the vulnerable endpoint via HTTP: GET /DIAE_privgrpHandler.ashx or /Handler/DIAE_privgrpHandler.ashx from the web server. The exact path depends on installation. A successful request (even if returning an error) indicates the handler is exposed.
    Affected if The handler responds to HTTP requests and the application version is unpatched
  4. Verify network exposure
    Determine if the web server hosting DIAEnergie is directly accessible from the internet or untrusted networks. Check firewall rules and bindings. The vulnerability is exploitable by unauthenticated attackers, so external accessibility is critical.
    Affected if The DIAEnergie web interface is exposed to untrusted networks without authentication barriers

You are affected if DIAEnergie with the vulnerable handler is installed and the version is prior to 1.8.02.004, regardless of whether the handler is currently exploitable from your network position.

Upgrade available Upgrade to 1.8.02.004 or later
Fixed in 1.8.02.004
Interim mitigation

Upgrade to DIAEnergie version 1.8.02.004 or later. If immediate patching is not feasible, implement web application firewall rules to block SQL injection attempts against the affected handler and restrict network access to the management interface.

Recommended fix High confidence

1.8.02.004

  1. Identify current DIAEnergie version by checking the application or system information
  2. Download DIAEnergie version 1.8.02.004 or later from the official Delta Electronics source
  3. Backup the current DIAEnergie installation and database before upgrading
  4. Install the updated version 1.8.02.004 following Delta Electronics upgrade documentation
  5. Verify the upgrade was successful by checking the new version number
  6. Test that the DIAE_privgrpHandler.ashx functionality works correctly after the upgrade
