Descriptions

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Malwarebytes Antimalware 3.6.1.2711. User interaction is required to exploit this vulnerability in that the target must visit a malicious web page. There is an issue with the way the product handles URIs within certain schemes. The product does not warn the user that a dangerous navigation is about to take place. Because special characters in the URI are not sanitized, this could lead to the execution of arbitrary commands. An attacker can leverage this vulnerability to execute code in the context of the current user at medium integrity. Was ZDI-CAN-7162.

Esta vulnerabilidad permite a los atacantes remotos ejecutar código arbitrario en instalaciones vulnerables de Malwarebytes Antimalware 3.6.1.2711. La interacción del usuario es necesaria para aprovechar esta vulnerabilidad, ya que el objetivo debe visitar una página web malintencionada. Hay un problema con la forma en que el producto maneja los URI dentro de ciertos esquemas. El producto no advierte al usuario de que se va a realizar una navegación peligrosa. Debido a que los caracteres especiales en el URI no están desinfectados, esto podría llevar a la ejecución de comandos arbitrarios. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del usuario actual con una integridad media. Fue ZDI-CAN-7162.
