CVE-2006-4556
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 index.php in the JIM component for Mambo and Joomla! allows remote attackers to execute arbitrary PHP code via a URL in the mosConfig_absolute_path parameter. NOTE: another researcher has stated that the product distribution does not include an index.php file. Also, this might be related to CVE-2006-4242
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 confidenceRemote file inclusion vulnerability in the JIM component for Mambo/Joomla allows execution of arbitrary PHP code through the mosConfig_absolute_path parameter in index.php, enabling attackers to include malicious remote 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.
-
Identify JIM component installationSearch the web server filesystem for the JIM component directory. For Joomla, check /components/com_jim/ or similar paths. For Mambo, check the same or analogous component directories.Affected if The directory /components/com_jim/ or a Jim component folder exists in the CMS installation.
-
Locate vulnerable index.phpLook for index.php within the JIM component directory that handles the mosConfig_absolute_path parameter.Affected if The file index.php in the JIM component directory contains references to mosConfig_absolute_path.
-
Check PHP allow_url_fopen settingRun phpinfo() or check php.ini for the allow_url_fopen directive.Affected if allow_url_fopen is enabled (set to On).
-
Check PHP allow_url_include settingRun phpinfo() or check php.ini for the allow_url_include directive.Affected if allow_url_include is enabled (set to On).
-
Test vulnerable parameterSend a crafted request to the JIM component index.php with mosConfig_absolute_path set to a remote URL (e.g., http://example.com/malicious.txt) and observe if the application attempts to include it.Affected if The application processes the mosConfig_absolute_path parameter and attempts to include content from the supplied remote URL.
A Mambo or Joomla installation with the JIM component present and PHP configured with allow_url_fopen or allow_url_include enabled is vulnerable to remote code execution via this RFI flaw.

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 dataDisable allow_url_fopen/allow_url_include in PHP configuration, implement strict input validation on the mosConfig_absolute_path parameter, or remove the vulnerable JIM component if unused.
