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
Joomla! 3.0.x through 3.0.2 allows attackers to obtain sensitive information via unspecified vectors related to an "Undefined variable."

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

This is an information disclosure vulnerability in Joomla! CMS versions 3.0.x through 3.0.2. The flaw stems from an undefined variable issue that can be exploited to obtain sensitive information through unspecified attack vectors. The CVSS score of 5 indicates moderate severity, likely requiring some form of authentication or specific conditions to exploit.

MitigationUpgrade Joomla! to version 3.0.3 or later, which contains the patch addressing this undefined variable vulnerability.

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 Joomla version
    Access the Joomla administrator dashboard and navigate to Help > System Information, or inspect the configuration.php file in the Joomla root directory for version constants
    Affected if The displayed version shows 3.0.0 or 3.0.1
  2. Verify Joomla core files match affected release
    Check the libraries/cms/version/version.php file or similar core version definition files for the exact version number string
    Affected if The version string explicitly reads 3.0.0 or 3.0.1
  3. Confirm Joomla edition and installation path
    Review the configuration.php file for the $mosConfig_live_site variable or site URL to identify the Joomla installation being assessed
    Affected if Multiple Joomla installations exist and the affected version 3.0.0/3.0.1 is present on any monitored site

The environment is affected if the installed Joomla CMS version is exactly 3.0.0 or 3.0.1, as these versions contain the undefined variable vulnerability that can leak sensitive information.
