CVE-2006-4863
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 · uneditedMultiple PHP remote file inclusion vulnerabilities in Marc Cagninacci mcLinksCounter 1.1 allow remote attackers to execute arbitrary PHP code via a URL in the langfile parameter in (1) login.php, (2) stats.php, (3) detail.php, or (4) erase.php. NOTE: CVE and a third party dispute this vulnerability, because the langfile parameter is set to english.php in each file. NOTE: CVE also disputes a later report of this vulnerability in 1.2, because the langfile parameter is set to french.php in 1.2
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 mcLinksCounter 1.1 allows arbitrary PHP code execution via the langfile parameter in login.php, stats.php, detail.php, and erase.php. However, the CVE notes dispute actual exploitability since the langfile parameter is hardcoded to english.php in each affected file, potentially requiring additional configuration to exploit.

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 mcLinksCounter installationLocate the mcLinksCounter application files on the server, typically in the web root or a subdirectory. Look for the main script files including login.php, stats.php, detail.php, and erase.php.Affected if The mcLinksCounter application version 1.1 is found on the system.
-
Verify the installed versionCheck for a version file, README, or any file within the mcLinksCounter directory that displays the version number. Common locations include a version.php file, a README file, or the main index.php header.Affected if The installed version is exactly 1.1.
-
Inspect langfile parameter in affected PHP filesOpen each of the following files: login.php, stats.php, detail.php, and erase.php. Search for the 'langfile' parameter usage. Determine whether it is hardcoded to 'english.php' or if user input can control the value passed to this parameter.Affected if The langfile parameter accepts user input and is not hardcoded to english.php, or the code logic allows override of the default value.
-
Check PHP allow_url_include settingReview the PHP configuration file (php.ini) or run phpinfo() to check the current value of the allow_url_include directive.Affected if allow_url_include is enabled (set to On), which would permit remote file inclusion attacks.
-
Test parameter controllabilityIf the affected files are accessible via HTTP, attempt a controlled test request to one of the affected files (login.php, stats.php, detail.php, or erase.php) with a modified langfile parameter value to see if the application attempts to include an external file.Affected if The application processes the langfile parameter from the request rather than using the hardcoded english.php value.
A system is affected if mcLinksCounter version 1.1 is installed AND the langfile parameter in the affected PHP files can be controlled via user input (not truly hardcoded) AND allow_url_include is enabled in PHP configuration.

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 dataReplace dynamic langfile parameter usage with hardcoded language file paths, implement input validation, or disable allow_url_include in PHP configuration to prevent RFI attacks.
