CVE-2006-4217
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 · uneditedPHP remote file inclusion vulnerability in modules/usersonline/users.php in WEBInsta CMS 0.3.1 allows remote attackers to execute arbitrary PHP code via a URL in the module_dir parameter, a different vulnerability than CVE-2006-4196. NOTE: the provenance of this information is unknown; the details are obtained from third party information.
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 · moderate confidenceRemote file inclusion vulnerability in WEBInsta CMS 0.3.1 allows remote attackers to execute arbitrary PHP code by supplying a URL in the module_dir parameter to modules/usersonline/users.php. The parameter is not validated, enabling inclusion of malicious remote PHP files.

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.
-
Confirm WEBInsta CMS installationLocate the CMS installation directory and check for version indicators such as a version.php file, a readme file, or the main index.php file which may contain version information. Look for files like 'version.txt', 'readme.txt', or inspect the source code for a version constant.Affected if The installed version is WEBInsta CMS 0.3.1 or any earlier version (version <= 0.3.1)
-
Verify vulnerable file presenceCheck if the file modules/usersonline/users.php exists in the web root or CMS installation directory.Affected if The file modules/usersonline/users.php exists on the server
-
Check PHP allow_url_include settingCreate a PHP script with '<?php phpinfo(); ?>' and access it in a browser, or check the PHP configuration file (php.ini) for the 'allow_url_include' directive.Affected if allow_url_include is set to On (enabled) in PHP configuration - this is required for remote file inclusion to succeed
-
Inspect module_dir parameter usageExamine the source code of modules/usersonline/users.php and look for include or require statements that use the module_dir parameter without validation, such as 'include($module_dir . "/something")' or 'require($module_dir)'Affected if The code contains unsanitized include/require statements using the module_dir parameter without proper validation
You are affected if WEBInsta CMS version 0.3.1 or lower is installed, the vulnerable file modules/usersonline/users.php exists, and PHP allow_url_include is enabled.

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 from the obsolete WEBInsta CMS 0.3.1 to a supported CMS platform; if continued use is required, implement strict input validation on the module_dir parameter and disable allow_url_include in PHP configuration.
