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 open_form.php in osTicket allows remote attackers to execute arbitrary PHP code via a URL in the include_dir 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 osTicket's open_form.php allows remote attackers to inject arbitrary URLs through the include_dir parameter, enabling execution of remote PHP 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.
-
Identify osTicket installationLocate the osTicket web application directory on the server by checking web server document roots for osticket or support ticket system foldersAffected if osTicket is found installed on the server
-
Verify open_form.php existsCheck for the presence of the file open_form.php within the osTicket installation directory, typically in the main include or scp foldersAffected if open_form.php file exists in the osTicket installation
-
Confirm include_dir parameter usageInspect the open_form.php source code and look for code that uses the include_dir parameter in a dynamic include or require statement without proper sanitizationAffected if The code contains an include or require statement using the include_dir parameter without input validation
-
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 directiveAffected if allow_url_include is enabled (set to On)
-
Test the vulnerable parameterIf the application is accessible, send a crafted HTTP request to open_form.php with an external URL in the include_dir parameter to observe if the application attempts to include the remote fileAffected if The application processes and attempts to include a remote file from the supplied include_dir parameter
If osTicket with an accessible open_form.php that uses the include_dir parameter without validation is present, and PHP allow_url_include is enabled, the environment is vulnerable to remote code execution via CVE-2006-5407
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 dataUpgrade osTicket to a patched version that addresses this vulnerability. Additionally, disable allow_url_include in PHP configuration and implement strict input validation on the include_dir parameter.
