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_loopmapHandler.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

A blind SQL injection vulnerability exists in the DIAE_loopmapHandler.ashx component of Delta Electronics DIAEnergie (all versions prior to 1.8.02.004). Attackers can inject arbitrary SQL queries through this handler, potentially allowing database content retrieval/modification and OS command execution.

MitigationUpdate DIAEnergie to version 1.8.02.004 or later to patch the vulnerability. As an interim measure, restrict network access to the affected service and consider WAF rules to detect SQL injection attempts.

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
    Locate the DIAEnergie installation directory on the system. Check common installation paths or look for files named DIAEnergie, DIAE_loopmapHandler.ashx, or related components.
    Affected if DIAEnergie software is found on the system
  2. Determine installed version
    Locate version information for DIAEnergie. Check the application itself, installation logs, or version metadata files. Compare the found version against 1.8.02.004.
    Affected if The installed version is lower than 1.8.02.004
  3. Locate vulnerable handler file
    Search for the file DIAE_loopmapHandler.ashx within the DIAEnergie web directory structure.
    Affected if The file DIAE_loopmapHandler.ashx exists in the application directory
  4. Check handler accessibility
    Verify that the DIAE_loopmapHandler.ashx endpoint is accessible over HTTP/HTTPS. Attempt a request to the handler path if you have access to test.
    Affected if The handler is accessible via network (HTTP/HTTPS)
  5. Confirm SQL injection point
    Review application logs or captured traffic for SQL injection attempts targeting loopmapHandler.ashx parameters. If authorized, send a test payload with SQL syntax to observe abnormal database behavior.
    Affected if The handler accepts user-supplied input that is not properly sanitized before being used in SQL queries

A system is affected if DIAEnergie with a version prior to 1.8.02.004 is installed and the DIAE_loopmapHandler.ashx component is accessible.

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

Update DIAEnergie to version 1.8.02.004 or later to patch the vulnerability. As an interim measure, restrict network access to the affected service and consider WAF rules to detect SQL injection attempts.

Recommended fix High confidence

1.8.02.004

  1. 1. Back up the current DIAEnergie installation and database before proceeding with the upgrade
  2. 2. Obtain DIAEnergie version 1.8.02.004 or later from official Delta Electronics channels
  3. 3. Upgrade the DIAEnergie installation to version 1.8.02.004 following Delta Electronics' standard upgrade procedures
  4. 4. After upgrade, verify that the DIAE_loopmapHandler.ashx handler is no longer vulnerable to SQL injection
  5. 5. Confirm the version has been successfully applied by checking the software version information
