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
PHP remote file inclusion vulnerability in gorum/dbproperty.php in PHPOutsourcing Zorum 3.5 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the appDirName parameter.

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

Remote file inclusion vulnerability in Zorum 3.5 and earlier allows arbitrary PHP code execution through the unsanitized appDirName parameter passed to gorum/dbproperty.php, enabling attackers to include malicious remote files.

MitigationDisable PHP's allow_url_include setting, implement strict input validation on the appDirName parameter to restrict it to local paths only, and upgrade to a patched version if available.

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 Zorum installation
    Look for Zorum web application files in the web root directory, typically in a folder named 'zorum' or 'Zorum', or check for files containing 'Zorum' branding in the application.
    Affected if Zorum phpoutsourcing software is present on the server.
  2. Identify installed Zorum version
    Locate and read the version file or any version indicator within the Zorum installation. Common locations include a version.php file, README file, or the main index.php header/comments showing version information.
    Affected if The installed version is 3.5 or any version numbered lower than 3.5.
  3. Verify vulnerable file exists
    Check for the presence of the file gorum/dbproperty.php within the Zorum installation directory.
    Affected if The file gorum/dbproperty.php exists and is accessible via web requests.
  4. Check if parameter is reachable
    Test accessing the vulnerable script directly via HTTP request to gorum/dbproperty.php with a test value for the appDirName parameter, such as: /path/to/zorum/gorum/dbproperty.php?appDirName=test
    Affected if The script responds and accepts the appDirName parameter without proper validation or restrictions.
  5. Review PHP allow_url_include setting
    Check the PHP configuration file (php.ini) or use phpinfo() to determine if allow_url_include is enabled.
    Affected if allow_url_include is set to On, allowing remote file inclusions through the vulnerable parameter.

You are affected if Zorum version 3.5 or lower is installed, the gorum/dbproperty.php file exists, and the appDirName parameter is processed without sanitization.

Interim mitigation

Disable PHP's allow_url_include setting, implement strict input validation on the appDirName parameter to restrict it to local paths only, and upgrade to a patched version if available.
