CVE-2019-1943

A vulnerability in the web interface of Cisco Small Business 200, 300, and 500 Series Switches software could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by intercepting a user's HTTP request and modifying it into a request that causes the web interface to redirect the user to a specific malicious URL. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites.

Una vulnerabilidad en la interfaz web del software Cisco Small Business 200, 300 y 500 Series Switches podría permitir que un atacante remoto no autenticado redirija a un usuario a una página web maliciosa. La vulnerabilidad se debe a una validación incorrecta de entradas de los parámetros en una petición HTTP. Un atacante podría explotar esta vulnerabilidad al interceptar la solicitud HTTP de un usuario y modificarla en una solicitud que haga que la interfaz web redirija al usuario a una URL maliciosa específica. Este tipo de vulnerabilidad se conoce como ataque de redirección abierta y se usa en ataques de suplantación de identidad que hacen que los usuarios visiten sin saberlo sitios maliciosos.
