Exposure of Sensitive Information to an Unauthorized Actor
PHP-Nuke 6.x through 7.6 allows remote attackers to obtain sensitive information via a direct request to (1) index.php with the forum_admin parameter set, (2) the Surveys module, or (3) the Your_Account module, which reveals the path in a PHP error message.
CWE-200 - Information Exposure
An information exposure vulnerability is categorized as an information flow (IF) weakness, which can potentially allow unauthorized access to otherwise classified information in the application, such as confidential personal information (demographics, financials, health records, etc.), business secrets, and the application's internal environment.
