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
There is a file disclosure vulnerability in SMF (Simple Machines Forum) affecting versions through v2.0.3. On some configurations a SMF deployment is shared by several "co-admins" that are not trusted beyond the SMF deployment. This vulnerability allows them to read arbitrary files on the filesystem and therefore gain new privileges by reading the settings.php with the database passwords.

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 confidence

SMF v2.0.3 and earlier contains a file disclosure vulnerability allowing authenticated co-admin users to read arbitrary files on the filesystem via path traversal, enabling access to sensitive configuration files like settings.php containing database credentials.

MitigationUpgrade SMF to a patched version beyond v2.0.3, or apply vendor-provided patches for this vulnerability. If upgrade is not feasible, restrict co-admin access and ensure web server permissions prevent the SMF application user from accessing sensitive configuration files outside the web root.

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 SMF installation and version
    Locate the SMF installation directory and check the version. Typically found in the main index.php file or a Version.php file within the SMF directory. Look for a version string such as '2.0.3' or earlier.
    Affected if The installed SMF version is 2.0.3 or any earlier version.
  2. Verify co-admin user access exists
    Check the SMF database (typically in the settings table or membergroup definitions) for user accounts assigned the co-admin role (usually membergroup ID 2 or a custom group with co-admin permissions).
    Affected if There are user accounts with co-admin or equivalent elevated privileges in the SMF installation.
  3. Confirm the path traversal parameter is accessible
    The vulnerability exists in an SMF component that accepts file path parameters. Identify if the SMF web interface is accessible and check if the vulnerable endpoint accepts user-supplied path input.
    Affected if The SMF web interface is accessible and accepts file path parameters without proper sanitization.
  4. Inspect file permissions on settings.php
    Locate the settings.php file within the SMF directory structure (typically in the same directory as index.php) and verify file system permissions. Check if the web server process has read access to this file.
    Affected if The settings.php file containing database credentials is readable by the web server user and the SMF version is 2.0.3 or earlier.

You are affected if SMF version 2.0.3 or earlier is installed, co-admin user accounts exist in the system, and sensitive configuration files are readable by the web server process.

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 data
Upgrade available Upgrade to a release after 2.0.3
Interim mitigation

Upgrade SMF to a patched version beyond v2.0.3, or apply vendor-provided patches for this vulnerability. If upgrade is not feasible, restrict co-admin access and ensure web server permissions prevent the SMF application user from accessing sensitive configuration files outside the web root.
