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
PHP remote file inclusion vulnerability in Bookmark4U 2.0.0 and earlier allows remote attackers to include arbitrary PHP files via the include_prefix parameter in (1) inc/dbase.php, (2) inc/config.php, (3) inc/common.php, and (4) inc/function.php. NOTE: it has been reported that the inc directory is protected by a .htaccess file, so this issue only applies in certain environments or configurations.

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

Bookmark4U 2.0.0 and earlier contains a PHP remote file inclusion vulnerability where the include_prefix parameter in inc/dbase.php, inc/config.php, inc/common.php, and inc/function.php allows attackers to include arbitrary PHP files from remote sources, leading to potential code execution.

MitigationRemediate by implementing strict input validation on the include_prefix parameter (e.g., whitelist allowed values, disable allow_url_include), or upgrade to a patched version if available. The .htaccess protection noted may need review to ensure it's effective in the deployment environment.

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 Bookmark4U installation
    Search the web server document root for directories containing 'bookmark4u', 'bookmark', or 'bookmark4U' (case-insensitive). Common paths: /var/www/html/bookmark4u, /home/*/public_html/bookmark4u, or C:\inetpub\wwwroot\bookmark4u
    Affected if Bookmark4U is found on the server
  2. Identify Bookmark4U version
    Open any version file such as version.php, readme.txt, or index.php in the Bookmark4U directory and search for a version string (e.g., '2.0.0', '1.9', '1.5'). Check the main index.php or a dedicated version file for the version number
    Affected if The installed version is 2.0.0 or earlier (any version <= 2.0)
  3. Verify vulnerable PHP files exist
    Check for the existence of these files within the Bookmark4U inc/ directory: dbase.php, config.php, common.php, and function.php. List the contents of the inc/ folder to confirm
    Affected if All four files (inc/dbase.php, inc/config.php, inc/common.php, inc/function.php) exist in the installation
  4. Confirm include_prefix parameter usage
    Open each vulnerable file (inc/dbase.php, inc/config.php, inc/common.php, inc/function.php) and search for 'include_prefix' or 'include' statements that use this parameter, e.g., 'include($include_prefix . ...)' or 'include_once($include_prefix . ...)'
    Affected if The code contains include/require statements using the include_prefix parameter without sanitization
  5. Check PHP allow_url_include setting
    Create a PHP file with '<?php phpinfo(); ?>' and access it via the web server, or run 'php -i' from command line. Look for the 'allow_url_include' directive in the output
    Affected if allow_url_include is enabled (On) in php.ini or PHP configuration

A user is affected if Bookmark4U version 2.0 or earlier is installed with the vulnerable inc/ files present and allow_url_include is enabled in PHP, allowing remote file inclusion via the include_prefix parameter.

Interim mitigation

Remediate by implementing strict input validation on the include_prefix parameter (e.g., whitelist allowed values, disable allow_url_include), or upgrade to a patched version if available. The .htaccess protection noted may need review to ensure it's effective in the deployment environment.
