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
Exponent CMS 0.96.3 and later versions includes the full installation path in the base parameter to thumb.php, which allows remote attackers to obtain sensitive information. NOTE: this might be resultant from an absolute path traversal vulnerability.

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

Exponent CMS 0.96.3 and later versions expose the full server installation path through the 'base' parameter in thumb.php, allowing remote attackers to obtain sensitive path information that could aid in further attacks.

MitigationRemove or sanitize the base parameter in thumb.php to prevent full path disclosure, and implement proper error handling that does not reveal system paths.

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. Confirm Exponent CMS installation and version
    Locate the Exponent CMS installation directory and check for version information, typically found in the CMS about page, a version.php file, or the installer documentation within the web root
    Affected if The installed version is 0.94, 0.95, 0.96.1, 0.96.3, or 0.96.4
  2. Locate thumb.php in the web root
    Search the Exponent CMS installation directory for thumb.php, which is commonly located in the main CMS folder or an includes directory accessible via web request
    Affected if thumb.php exists and is web-accessible in the Exponent CMS installation
  3. Test the base parameter for path disclosure
    Send an HTTP request to thumb.php with a crafted 'base' parameter (for example: thumb.php?base=invalid or thumb.php?base=../) and observe if the error response or output reveals the full server file system path
    Affected if The response displays the full absolute server path to the Exponent CMS installation directory

The environment is affected if Exponent CMS version 0.94, 0.95, 0.96.1, 0.96.3, or 0.96.4 is installed, thumb.php is accessible, and the base parameter can be manipulated to disclose the server's file system paths in the response.
