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
tiki-wiki_rss.php in Tikiwiki 1.9.5, 1.9.2, and possibly other versions allows remote attackers to obtain sensitive information (MySQL username and password) via an invalid (large or negative) ver parameter, which leaks the information in an error message.

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

Tikiwiki's tiki-wss.php script fails to properly validate the 'ver' parameter. When a large or negative integer is provided, the script triggers a PHP/MySQL error that exposes the database credentials (username and password) in the error message output.

MitigationUpdate Tikiwiki to a patched version that properly validates the ver parameter and/or disable verbose error messages in production to prevent credential disclosure.

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. Locate tiki-wss.php script
    Search the web server document root for the file tiki-wss.php (e.g., find /var/www -name 'tiki-wss.php' or check common paths like /tiki-wss.php, /scripts/tiki-wss.php)
    Affected if The file exists in the web-accessible directory
  2. Identify Tikiwiki version
    Check the Tikiwiki version by inspecting the tiki-version.php file, the CHANGELOG.txt, or the admin panel under Admin > System > Info
    Affected if The installed version is 1.9.2 or 1.9.5 exactly (note: only these two specific versions are affected)
  3. Confirm PHP error display is enabled
    Check the PHP configuration (php.ini) for display_errors = On, or inspect the site-level config for error reporting settings
    Affected if display_errors is enabled (this is required for the credential disclosure to be visible in the error output)
  4. Test the vulnerable parameter
    Send a GET request to tiki-wss.php with an oversized or negative integer for the 'ver' parameter, e.g., tiki-wss.php?ver=999999999 or tiki-wss.php?ver=-1
    Affected if The response contains a PHP/MySQL error that exposes database credentials (username or password strings in the error message)

You are affected if tiki-wss.php is present, your Tikiwiki version is exactly 1.9.2 or 1.9.5, PHP error display is enabled, and the ver parameter triggers an error that leaks database credentials.

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