CVE-2006-3777
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 IDevSpot PhpLinkExchange 1.0 allows remote attackers to execute arbitrary PHP code via a URL in the page parameter.
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 index.php of IDevSpot PhpLinkExchange 1.0 where the 'page' parameter is not properly sanitized, allowing attackers to include remote PHP files and execute arbitrary code.

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 IDevSpot PhpLinkExchange is installedLocate the application by searching for index.php files that contain 'PhpLinkExchange' or 'phplinkexchange' in the source code. Check web server document roots for the application directory.Affected if The application files (particularly index.php) are found on the server.
-
Verify the exact version is 1.0Open index.php or any configuration file and search for a version string such as 'version', '$version', or '1.0'. Check README or install files for version information.Affected if The installed version is exactly 1.0.
-
Inspect the 'page' parameter handling in index.phpOpen index.php and locate where the 'page' parameter is processed (e.g., include(), require(), include_once()). Check if the value is used directly in include/require statements without sanitization or validation.Affected if The 'page' parameter is used in an include/require statement without input validation or whitelist filtering.
-
Check PHP configuration for remote file inclusion settingsReview the PHP configuration file (php.ini) or create a PHP info page to check the values of allow_url_fopen and allow_url_include.Affected if allow_url_fopen is enabled (On) or allow_url_include is enabled (On).
-
Determine if the application is network-accessibleVerify the application's URL is accessible from outside the local network or from non-trusted IP addresses. Check web server access logs for external requests to index.php.Affected if The application is accessible from untrusted network locations.
The environment is affected if IDevSpot PhpLinkExchange version 1.0 is installed, the 'page' parameter in index.php includes user input without validation, and PHP's allow_url_fopen or allow_url_include is enabled with the application exposed to untrusted access.

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 dataImplement strict whitelist-based validation for the 'page' parameter to only allow known, safe page names, and disable allow_url_fopen and allow_url_include in PHP configuration.
