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
The Standard Remember method in TikiWiki CMS/Groupware 3.x before 3.5 allows remote attackers to bypass access restrictions related to "persistent login," probably due to the generation of predictable cookies based on the IP address and User agent in userslib.php.

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

The Standard Remember method in TikiWiki CMS/Groupware 3.x before 3.5 uses predictable values (IP address and User agent) to generate authentication cookies in userslib.php. This allows remote attackers to craft valid persistent login cookies and bypass authentication, gaining unauthorized access to user accounts.

MitigationReplace the predictable cookie generation algorithm with cryptographically secure random values (e.g., using random_bytes() or similar) and implement proper session token validation rather than relying on IP/UA combinations.

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 TikiWiki version
    Check the version file or admin panel for the exact TikiWiki CMS/Groupware version number
    Affected if The installed version is 3.0, 3.1, 3.2, 3.3, or 3.4 (versions before 3.5)
  2. Locate userslib.php authentication code
    Find the userslib.php file in the TikiWiki installation directory and examine the remember me cookie generation function
    Affected if The file contains cookie generation logic using IP address and User agent string concatenation without cryptographic randomization
  3. Verify remember me feature is enabled
    Check the TikiWiki authentication settings (tiki-login.php or admin panel) for the 'remember me' or 'Standard Remember' login option
    Affected if The Standard Remember method is active and cookies are being generated for persistent sessions
  4. Examine cookie structure
    Inspect a remember me cookie in the browser or capture one via network logging; check if it contains predictable values like IP address or User agent
    Affected if The cookie value can be reconstructed using only client IP and User agent information

A user is affected if they are running TikiWiki versions 3.0 through 3.4 with the Standard Remember feature enabled, as the authentication cookie generation relies on predictable IP/UA values rather than cryptographic randomness.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Replace the predictable cookie generation algorithm with cryptographically secure random values (e.g., using random_bytes() or similar) and implement proper session token validation rather than relying on IP/UA combinations.
