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 · unedited
Multiple PHP remote file inclusion vulnerabilities in Phorum 5.1.14, when register_globals is enabled, allow remote attackers to execute arbitrary PHP code via unspecified vectors related to an uninitialized variable.

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 confidence

Phorum 5.1.14 contains multiple remote file inclusion vulnerabilities where an uninitialized variable can be manipulated to include remote PHP code, leading to arbitrary code execution. The vulnerability is exploitable when PHP's register_globals setting is enabled, a legacy configuration that was common in older PHP installations.

MitigationDisable PHP's register_globals setting in php.ini or .htaccess, and upgrade Phorum to a current supported version that does not rely on register_globals.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Phorum version
    Locate the version file in your Phorum installation (commonly includes/version.php or similar), or check the admin interface for the version number
    Affected if The installed version is Phorum 5.1.14 exactly, as this is the only version listed as affected in this CVE
  2. Check PHP register_globals setting
    Create a PHP info page (<?php phpinfo(); ?>) and search for 'register_globals' in the output, or check your php.ini file for 'register_globals = On'
    Affected if register_globals is set to On - this is the critical configuration required for the uninitialized variable exploitation to succeed
  3. Identify vulnerable include statements in Phorum code
    Search Phorum source files for uninitialized variable usage in include/require statements (common patterns: include($var); or include($path."/file.php");) particularly in common.php or other core files
    Affected if Code contains include/require statements using uninitialized variables that could be manipulated via URL parameters when register_globals is enabled

You are affected if running Phorum 5.1.14 with PHP register_globals enabled, allowing remote file inclusion via manipulated uninitialized variables in the codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Disable PHP's register_globals setting in php.ini or .htaccess, and upgrade Phorum to a current supported version that does not rely on register_globals.
