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! Core is prone to a security bypass vulnerability. Exploiting this issue may allow attackers to perform otherwise restricted actions and subsequently retrieve password reset tokens from the database through an already existing SQL injection vector. Joomla! Core versions 1.5.x ranging from 1.5.0 and up to and including 1.5.15 are vulnerable.

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

Joomla! Core 1.5.x versions 1.5.0-1.5.15 contains a security bypass vulnerability allowing attackers to bypass authentication restrictions and exploit an existing SQL injection vector to retrieve password reset tokens from the database. This critical pre-authentication flaw enables complete account takeover.

MitigationUpgrade Joomla! Core to version 1.5.16 or later which contains the security fix. If immediate upgrade is not feasible, deploy WAF rules to mitigate SQL injection attempts and review access logs for indicators of compromise.

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 Joomla installation version
    Access the Joomla administrator backend and navigate to Help > System Info > Version Information, or check the /libraries/joomla/version.php file for the $RELEASE variable defining the 1.5.x branch
    Affected if The installed version falls within the range 1.5.0 through 1.5.15 inclusive
  2. Verify user registration is enabled
    In the Joomla administrator panel, go to Users > Manage > Options, or inspect the configuration.php file for the parameter $this->allowUserRegistration = 1
    Affected if User registration is set to enabled, providing an attack vector for account creation and token retrieval
  3. Check for compromised password reset activity
    Review the jos_users database table for any unexpected password reset tokens (字段: resetToken) or examine web server access logs for repeated requests to /index.php?option=com_user&view=reset
    Affected if Unexpected password reset tokens exist in the database or anomalous reset request patterns appear in logs indicating exploitation attempts

The environment is affected if Joomla Core version 1.5.0-1.5.15 is installed AND user registration or the remember me functionality is enabled, allowing unauthenticated SQL injection to retrieve password reset tokens.

Upgrade available Upgrade to a release after 1.5.15
Interim mitigation

Upgrade Joomla! Core to version 1.5.16 or later which contains the security fix. If immediate upgrade is not feasible, deploy WAF rules to mitigate SQL injection attempts and review access logs for indicators of compromise.

Recommended fix High confidence

Joomla! 1.5.16 or later (ideally migrate to Joomla 3.x/4.x as 1.5.x is end-of-life)

  1. Download Joomla! 1.5.16 or later from the official Joomla! archives or repository
  2. Backup the existing Joomla! database and filesystem
  3. Replace the core Joomla! files with the new version, preserving the configuration.php file and any custom templates or extensions
  4. Verify the installation by accessing the administrator dashboard
  5. Check that all third-party extensions are compatible with the new Joomla! version
Caveat Joomla 1.5.x is end-of-life and no longer receives security updates; third-party extensions may not be compatible with newer versions; a full migration to Joomla 3.x or 4.x is strongly recommended
