Description
CubeCart is an ecommerce software solution. Prior to 6.6.0, a Stored Cross-Site Scripting (XSS) vulnerability exists in CubeCart v6.x. An attacker with administrative privileges can inject malicious JavaScript payloads into multiple fields during the creation or modification of a product. These payloads are stored in the database and executed whenever a user (customer or another administrator) views the affected product pages, which could lead to session hijacking or unauthorized actions. This vulnerability is fixed in 6.6.0.
A stored cross-site scripting vulnerability has been identified in CubeCart versions prior to 6.6.0. This issue allows an attacker with administrative privileges to inject malicious JavaScript into several product fields. The injected scripts are saved in the database and executed when users view the affected product pages, potentially leading to session hijacking or unauthorized actions. The vulnerability arises from inadequate input sanitization and output encoding, allowing HTML and JavaScript to be stored and executed.
Users are advised to update CubeCart to version 6.6.0 or later, where this vulnerability has been fixed.
