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 chameleon cms 3.0 and earlier allows remote attackers to hijack web sessions by setting the PHPSESSID 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

Session fixation vulnerability in Chameleon CMS 3.0 and earlier allows remote attackers to hijack web sessions by setting the PHPSESSID parameter. The application accepts user-controlled session IDs, enabling attackers to pre-establish a known session ID before victim authentication, then hijack the authenticated session.

MitigationImplement session ID regeneration upon successful authentication and reject session IDs provided via URL parameters or untrusted sources. Use secure session management practices such as regenerating session IDs and validating session integrity.

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 Chameleon CMS installation
    Locate Chameleon CMS files in the webroot or check for the presence of Chameleon-specific directories and configuration files
    Affected if Chameleon CMS is present on the server and the version is 3.0 or lower
  2. Determine installed version
    Check version information in Chameleon CMS files, typically found in version files, changelogs, or the administrative interface
    Affected if The installed version is 3.0 or any version labeled as 3.0 and earlier
  3. Test session ID acceptance from URL
    Attempt to access a Chameleon CMS page with an arbitrary PHPSESSID value appended to the URL (e.g., ?PHPSESSID=attackercontrolled123) and observe if the application accepts and uses this session ID
    Affected if The application accepts and maintains the user-supplied PHPSESSID without regenerating it
  4. Verify session behavior after authentication
    Create a test account, set a known PHPSESSID before login, authenticate, then check whether the session ID remains the same or is regenerated
    Affected if The session ID remains unchanged after successful authentication (session fixation is possible)

A user is affected if Chameleon CMS version 3.0 or earlier is installed AND the application accepts user-supplied PHPSESSID values without regenerating the session ID upon authentication.

Interim mitigation

Implement session ID regeneration upon successful authentication and reject session IDs provided via URL parameters or untrusted sources. Use secure session management practices such as regenerating session IDs and validating session integrity.
