Detailsinfo

A vulnerability, which was classified as critical, was found in WWBN AVideo up to 26.0. This affects the function Subscribe::save of the file objects/subscribe.php of the component Database Table Handler. The manipulation of the argument user_id with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `Subscribe::save()` method in `objects/subscribe.php` concatenates the `$this->users_id` property directly into an INSERT SQL query without sanitization or parameterized binding. This property originates from `$_POST['user_id']` in both `subscribe.json.php` and `subscribeNotify.json.php`. An authenticated attacker can inject arbitrary SQL to extract sensitive data from any database table, including password hashes, API keys, and encryption salts. Commit 36dfae22059fbd66fd34bbc5568a838fc0efd66c contains a patch.
