CVE-2006-5520
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 functions.php in DeltaScripts PHP Classifieds 7.1 allows remote attackers to execute arbitrary PHP code via a URL in the set_path 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 DeltaScripts PHP Classifieds 7.1 functions.php. The set_path parameter is not validated, allowing attackers to supply a remote URL that gets included and executed as PHP code, leading to complete server compromise.

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 DeltaScripts PHP Classifieds versionLocate and read the version file or index file in the webroot (commonly version.php, about.php, or check the HTML source for version metadata). Compare the found version to 7.1.Affected if The installed version is exactly 7.1
-
Verify functions.php existsCheck if the file functions.php exists in the scripts/includes or main application directory accessible via web. Common paths include /include/functions.php or /scripts/functions.php.Affected if functions.php exists and is web-accessible
-
Inspect set_path parameter handling in functions.phpOpen functions.php and search for the set_path variable/parameter usage. Look for include, include_once, require, or require_once statements that use set_path without validation (no file_exists, no realpath, no whitelist check).Affected if set_path is used in an include/require statement without input validation or path sanitization
-
Check PHP allow_url_fopen settingCreate a PHP info page (<?php phpinfo(); ?>) or check existing configuration via command line: php -i | grep allow_url_fopen. Alternatively, check php.ini for allow_url_fopen = On.Affected if PHP allow_url_fopen is enabled (On)
-
Check PHP allow_url_include settingRun: php -i | grep allow_url_include or inspect php.ini directly.Affected if PHP allow_url_include is enabled (On) - this specifically allows including remote URLs
You are affected if DeltaScripts PHP Classifieds version 7.1 is installed, functions.php with unvalidated set_path parameter is web-accessible, and PHP has allow_url_fopen enabled (or allow_url_include for easier exploitation).
Generated from the published advisory. Verify against your own 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 dataSanitize and validate the set_path parameter to only accept trusted paths, disable PHP's allow_url_fopen/allow_url_include settings, or upgrade to a patched version of the software.
