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
SQL injection vulnerability in Advanced Electron Forum (AEF) 1.x, when magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary SQL commands via the filename in an uploaded attachment. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

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

SQL injection vulnerability in AEF 1.x allows remote attackers to execute arbitrary SQL commands through the attachment filename parameter during file upload processing. The vulnerability is exploitable when PHP's magic_quotes_gpc setting is disabled, which allows unsanitized input to reach the database query.

MitigationEnable magic_quotes_gpc as a temporary workaround; the primary fix requires code changes to use parameterized queries/prepared statements for the attachment filename handling in the upload module, replacing any string concatenation in SQL queries.

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 installed AEF version
    Check the version.php or version info file in the AEF installation directory, or look for version strings in the forum footer/admin panel
    Affected if version is 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.0.5, 1.0.6, 1.0.7, or 1.0.8
  2. Verify PHP magic_quotes_gpc setting
    Create a PHP script with phpinfo() or check php.ini for the magic_quotes_gpc value
    Affected if magic_quotes_gpc is set to Off or 0 (the vulnerability requires this to be disabled for exploitation)
  3. Confirm file attachment upload functionality
    Locate the file upload module in the AEF installation (typically in modules/upload or similar) and verify it handles attachment filenames
    Affected if the upload module processes attachment filenames without parameterized queries, using string concatenation in SQL statements

You are affected if you have AEF version 1.0.1-1.0.8 installed, magic_quotes_gpc is disabled, and the file attachment upload feature is active.
