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
Session fixation vulnerability in Joomla! before 1.0.13 (aka Sunglow) allows remote attackers to hijack administrative web sessions via unspecified vectors.

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

Session fixation vulnerability in Joomla! versions prior to 1.0.13 allows remote attackers to set or manipulate a user's session ID before authentication, then hijack the administrative session after the victim logs in using that fixed session identifier.

MitigationUpgrade to Joomla! 1.0.13 or later which includes session regeneration on authentication. Alternatively, implement session ID regeneration (session_regenerate_id()) immediately after successful login to prevent session fixation attacks.

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
    Locate the version.php file in your Joomla installation or check the administrator panel for the Joomla version number
    Affected if The installed version is any release prior to 1.0.13 (e.g., 1.0.12, 1.0.11, 1.0.10, etc.)
  2. Inspect session handling code
    Examine the session management code in the Joomla libraries directory, specifically looking for session regeneration logic that executes immediately after successful user authentication
    Affected if The code does not call session_regenerate_id() or equivalent session ID regeneration function right after a user successfully logs in
  3. Review configuration for session settings
    Check the configuration.php file for session-related configuration parameters that might control session ID handling during the login process
    Affected if No session regeneration mechanism is configured or enforced upon authentication

You are affected if your Joomla installation version is below 1.0.13 and the login process does not regenerate the session identifier after successful authentication.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 1.0.13 or later
Fixed in 1.0.13
Interim mitigation

Upgrade to Joomla! 1.0.13 or later which includes session regeneration on authentication. Alternatively, implement session ID regeneration (session_regenerate_id()) immediately after successful login to prevent session fixation attacks.

Recommended fix High confidence

Joomla! 1.0.13 (Sunglow)

  1. Download Joomla! 1.0.13 (Sunglow) from the official Joomla! archives at https://downloads.joomla.org/
  2. Backup the existing Joomla! installation and database before upgrading
  3. Extract the Joomla! 1.0.13 package to your web server
  4. Copy all files and folders from the package to replace existing Joomla! files
  5. Run the upgrade by accessing your Joomla! site URL - the upgrade script should automatically execute
  6. Verify the installation by logging into the administrator backend
  7. Check that the Joomla! version displays as 1.0.13 in the administrator panel
