Coppermine Photo Gallery contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a remote attacker sends a request to the thumbnails.php script via the 'page' and 'cat' parameters, which discloses the software's installation path resulting in a loss of confidentiality. While such information is relatively low risk, it is often useful in carrying out additional, more focused attacks.
