Descriptions

A vulnerability has been identified in Bitdefender Total Security HTTPS scanning functionality where the software fails to properly validate website certificates. Specifically, if a site certificate lacks the "Server Authentication" specification in the Extended Key Usage extension, the product does not verify the certificate's compliance with the site, deeming such certificates as valid. This flaw could allow an attacker to perform a Man-in-the-Middle (MITM) attack, intercepting and potentially altering communications between the user and the website.

Se ha identificado una vulnerabilidad en la función de análisis HTTPS de Bitdefender Total Security, en la que el software no puede validar correctamente los certificados de los sitios web. En concreto, si un certificado de sitio no tiene la especificación "Server Authentication" (Autenticación de servidor) en la extensión Extended Key Usage (Uso extendido de clave), el producto no verifica la conformidad del certificado con el sitio y considera que dichos certificados son válidos. Esta falla podría permitir a un atacante realizar un ataque Man-in-the-Middle (MITM), interceptando y potencialmente alterando las comunicaciones entre el usuario y el sitio web.
