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
PHP remote file inclusion vulnerability in ubbt.inc.php in UBBThreads 5.x and 6.x allows remote attackers to execute arbitrary PHP code via a URL in the (1) thispath or (2) configdir parameters.

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

UBBThreads 5.x and 6.x contains a remote file inclusion vulnerability in ubbt.inc.php where the thispath and configdir parameters are not properly sanitized before being used in include/require statements. An attacker can supply a malicious URL to these parameters, causing arbitrary PHP code execution on the target server.

MitigationDisable PHP's allow_url_include setting to prevent remote file inclusion attacks. Ideally, upgrade or migrate away from UBBThreads as it is legacy software no longer under active development.

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. Locate UBBThreads installation
    Search for ubbt.inc.php or common UBBThreads directories such as /forum/, /ubbthreads/, or /boards/. Check for the presence of the main UBBThreads script files (common filenames include ubbt.inc.php, ubbthreads.php, or similar).
    Affected if The file ubbt.inc.php exists in the web root or a subdirectory.
  2. Identify UBBThreads version
    Open the file common.php or a version file within the UBBThreads installation directory. Look for a variable such as $ubbt_version, $VERSION, or check a version.inc.php file. The affected versions range from 3.4 through 6.5.3.
    Affected if The installed version is 6.5.3 or lower, or matches 3.4, 3.5, 5.0, 5.5.1, 6.0, 6.0.1, 6.0.2, 6.0.3, 6.1, 6.1.1, or 6.2.
  3. Verify vulnerable script exists
    Confirm the file ubbt.inc.php exists in the installation. This is the file containing the vulnerable include/require statements that use the thispath and configdir parameters without sanitization.
    Affected if The file ubbt.inc.php is present and accessible via the web server.
  4. Check PHP allow_url_include setting
    Create a PHP script containing <?php echo ini_get('allow_url_include'); ?> and access it through the web server, or check the php.ini file directly.
    Affected if allow_url_include is set to 1 or On, which permits remote file inclusion attacks to succeed.

A user is affected if UBBThreads version 6.5.3 or lower (specifically 3.4, 3.5, 5.0, 5.5.1, 6.0-6.0.3, 6.1-6.2) is installed with ubbt.inc.php present and PHP's allow_url_include is enabled.

From vendor data
Upgrade available Upgrade to a release after 6.5.3
Interim mitigation

Disable PHP's allow_url_include setting to prevent remote file inclusion attacks. Ideally, upgrade or migrate away from UBBThreads as it is legacy software no longer under active development.
