CVE-2008-0450
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 BLOG:CMS 4.2.1.c allow remote attackers to execute arbitrary PHP code via a URL in the (1) DIR_PLUGINS parameter to (a) index.php, and the (2) DIR_LIBS parameter to (b) media.php and (c) xmlrpc/server.php in admin/.
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 confidenceMultiple remote file inclusion (RFI) vulnerabilities in BLOG:CMS 4.2.1.c allow remote attackers to execute arbitrary PHP code by supplying URLs through the DIR_PLUGINS parameter in index.php and the DIR_LIBS parameter in admin/media.php and admin/xmlrpc/server.php. The application includes files based on user-controlled input without validation, enabling remote code execution.

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.
-
Locate BLOG:CMS installationSearch the web server document root for index.php files that contain 'BLOG:CMS' or 'blog:cm' in the source code. Typical paths include /var/www/html/, /home/*/public_html/, or C:\inetpub\wwwroot\Affected if BLOG:CMS software is found on the server
-
Verify installed versionOpen the main index.php or a configuration file (such as nconfig.php or similar) in the installation directory and search for a version string. Look for '4.2.1' or '4.2.1_c' in the file contentsAffected if The version displayed is 4.2.1_c exactly
-
Confirm vulnerable scripts existCheck for the presence of admin/media.php and admin/xmlrpc/server.php files within the BLOG:CMS installation directory structureAffected if These admin script files exist in the installation
-
Test parameter accessibilitySend an HTTP GET request to index.php with a crafted DIR_PLUGINS parameter, for example: GET /index.php?DIR_PLUGINS=http://example.com/test. Similarly test admin/media.php?DIR_LIBS=http://example.com/test and admin/xmlrpc/server.php?DIR_LIBS=http://example.com/testAffected if The application attempts to include or resolve the URL supplied in the DIR_PLUGINS or DIR_LIBS parameter, indicating the vulnerability is present and exploitable
-
Check PHP allow_url_include settingCreate a PHP info file (info.php) with content '<?php phpinfo(); ?>' and access it via browser, or check php.ini directly for the allow_url_include directive valueAffected if allow_url_include is set to On (enabled)
A server is affected if BLOG:CMS version 4.2.1_c is installed, the vulnerable script files exist, and the DIR_PLUGINS or DIR_LIBS parameters can be manipulated to include remote URLs, especially when 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 dataImplement strict input validation using whitelist-based checks to ensure included files originate from expected directories, and disable allow_url_include in PHP configuration to prevent remote file inclusion.
