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. Confirm DedeCMS installation
    Identify DedeCMS by locating characteristic files such as index.php, the /dede/ admin directory, or DedeCMS-specific templates in the web root
    Affected if DedeCMS is present on the server
  2. Check DedeCMS version number
    Locate the version file or footer of DedeCMS pages to find the installed version; compare it to the affected range of <= 5.7.106
    Affected if Installed version is 5.7.106 or lower
  3. Verify vulnerable file exists
    Check if the file uploads/dede/article_allowurl_edit.php exists in the web root directory
    Affected if The file article_allowurl_edit.php exists in the uploads/dede/ directory
  4. Confirm admin directory accessibility
    Determine if the /dede/ admin directory is network-accessible from untrusted sources (the vulnerable file resides in this admin area)
    Affected if The /dede/ directory is accessible without proper network restrictions or authentication

The environment is affected if DedeCMS version 5.7.106 or lower is installed, the vulnerable file uploads/dede/article_allowurl_edit.php exists, and the /dede/ admin directory is network-accessible.
