CVE-2010-1434
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 · uneditedJoomla! Core is prone to a session fixation vulnerability. An attacker may leverage this issue to hijack an arbitrary session and gain access to sensitive information, which may help in launching further attacks. 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 confidenceJoomla! Core 1.5.x versions 1.5.0 through 1.5.15 suffer from a session fixation vulnerability where the application does not properly regenerate session IDs upon user authentication. Attackers can pre-set or force a known session ID before a user logs in, then hijack the authenticated session by using that same session ID to gain unauthorized access to sensitive information.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Joomla installation versionLocate the VERSION.php file in the Joomla installation (typically at /libraries/joomla/version.php or /includes/version.php) and read the RELEASE constant or version constants to determine the exact version numberAffected if The installed version falls within the range >= 1.5.0 and <= 1.5.15
-
Confirm Joomla core is being usedVerify that the site runs on Joomla core rather than a fork, by checking the file structure matches standard Joomla 1.5.x installation and the /libraries/joomla/ directory contains the standard session handling filesAffected if The site uses Joomla core 1.5.x rather than a later version or different CMS
-
Verify user authentication is enabledCheck if the Joomla user authentication system is active by confirming the com_user or com_users component is installed and functional, and that user registration/login functionality is present on the siteAffected if User login functionality is enabled and users can authenticate to the site, which triggers the session handling code path vulnerable to session fixation
-
Inspect session ID handling behaviorUse browser developer tools or a proxy to observe session cookies before and after a user logs in; capture the session cookie value before authentication, perform login, then check if the session ID changes after successful authenticationAffected if The session ID remains unchanged after authentication completes, indicating the session fixation vulnerability is present
The environment is affected if Joomla core version 1.5.0 through 1.5.15 is installed and user authentication functionality is active, with the session ID not being regenerated after login.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataUpgrade to Joomla 1.5.16 or later which includes the session ID regeneration fix. If upgrading is not feasible, implement custom code to regenerate session IDs immediately after successful authentication in the Joomla login process.
