Descriptions

A vulnerability in the web-based management interface of Cisco Webex Meetings could allow an unauthenticated, remote attacker to redirect a user to an untrusted web page, bypassing the warning mechanism that should prompt the user before the redirection. This vulnerability is due to improper input validation of the URL parameters in an HTTP request. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to redirect a user to a malicious website, bypassing the Webex URL check that should result in a warning before the redirection to the web page. Attackers may use this type of vulnerability, known as an open redirect attack, as part of a phishing attack to convince users to unknowingly visit malicious sites.

Una vulnerabilidad en la interfaz de administración basada en web de Cisco Webex Meetings, podría permitir a un atacante remoto no autenticado redirecciona a un usuario a una página web que no sea de confianza, sin pasar por el mecanismo de advertencia que debería avisar al usuario antes del redireccionamiento. Esta vulnerabilidad se debe a una validación de entrada incorrecta de los parámetros de URL en una petición HTTP. Un atacante podría explotar esta vulnerabilidad persuadiendo a un usuario para que haga clic en un vínculo creado. Una explotación con éxito podría permitir al atacante redirigir a un usuario a un sitio web malicioso, sin pasar por la verificación de URL de Webex que debería generar una advertencia antes del redireccionamiento a la página web. Los atacantes pueden utilizar este tipo de vulnerabilidad, conocida como ataque de redireccionamiento abierto, como parte de un ataque de phishing para convencer a los usuarios de que visiten sitios maliciosos sin saberlo.
