CVE-2007-4950
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 form/db_form/employee.php in PHPortal 0.2.7 allows remote attackers to execute arbitrary PHP code via a URL in the DOCUMENT_ROOT parameter. NOTE: this issue is disputed by CVE, since DOCUMENT_ROOT cannot be modified by an attacker
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 confidencePHPortal 0.2.7 contains a claimed file inclusion vulnerability in form/db_form/employee.php via the DOCUMENT_ROOT parameter. However, the CVE entry explicitly disputes this issue, noting that DOCUMENT_ROOT is a server environment variable that cannot be modified by an attacker, making exploitation unlikely or impossible.

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 PHPortal versionLocate the PHPortal installation directory and check version.php or any version file for the installed version numberAffected if version is 0.2.7 exactly
-
Locate the employee.php fileSearch for the file form/db_form/employee.php within the PHPortal installation directoryAffected if the file exists in the installation
-
Examine DOCUMENT_ROOT usage in employee.phpOpen form/db_form/employee.php in a text editor and locate any include(), require(), or similar statements that reference the DOCUMENT_ROOT variableAffected if the code uses DOCUMENT_ROOT in include statements with user-controlled input
-
Verify if DOCUMENT_ROOT can be influencedReview the include logic to determine whether any portion of the DOCUMENT_ROOT path is derived from user-supplied request parametersAffected if user input is combined with DOCUMENT_ROOT in include statements
-
Check server configurationVerify that the PHP server properly sets the DOCUMENT_ROOT environment variable from server configuration rather than allowing user overrideAffected if DOCUMENT_ROOT is not set by the web server or can be controlled by external input
A user is affected only if they are running PHPortal version 0.2.7, the employee.php file exists, AND user-supplied input is combined with the DOCUMENT_ROOT variable in include statements (though the CVE notes this is unlikely since DOCUMENT_ROOT is a server environment variable).

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 dataIf the code uses DOCUMENT_ROOT in include statements, ensure hardcoded base paths are used instead of relying on environment variables; verify the include() calls do not accept user-supplied input that could be combined with the variable.
