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
AlanWeb SCADA is vulnerable to SQL Injection across most scripts and input parameters. Because no protections are in place, an authenticated attacker can inject arbitrary SQL commands, potentially gaining full control over the database. This issue was fixed in AlanWeb SCADA version 9.8.5

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.

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 Hydrosystem Control System installation
    Locate the Hydrosystem Control System installation directory or check for the web application serving hydrosystem.poznan content. Look for files named hydrosystem.exe, hydrosystem.dll, or similar binaries, or check IIS/apache logs for hydrosystem.poznan requests.
    Affected if The system is running Hydrosystem Control System from hydrosystem.poznan
  2. Determine installed version
    Check the version of the Hydrosystem Control System installation. Common locations: about page in the web interface, version info in the binary/assembly metadata, or a version file in the installation directory. Compare the found version against the vulnerable range of < 9.8.5.
    Affected if The installed version is any version lower than 9.8.5
  3. Verify web interface accessibility
    Confirm the web management interface is exposed and accessible. Test HTTP/HTTPS access to the hydrosystem.poznan web application URL.
    Affected if The web interface is accessible without additional network restrictions
  4. Check authentication configuration
    Review the authentication mechanism configuration for the web application. Determine whether user authentication is properly enforced on all scripts and input endpoints.
    Affected if Authentication is disabled, weak, or not consistently enforced across all endpoints

The environment is affected if Hydrosystem Control System (hydrosystem.poznan) is installed with a version lower than 9.8.5 and has its web interface accessible.
