The attacker needs a valid developer account to exploit this vulnerability. The vulnerability is due to insufficient input validation when processing received adaptive cards. The attacker could exploit this vulnerability by sending an adaptive card with malicious content to an existing user of the Cisco Webex Teams client for Windows. A successful exploit could allow the attacker to cause the targeted user's client to crash continuously. This vulnerability was introduced in Cisco Webex Teams client for Windows Release 3.0.13131."},{"lang":"es","value":"Una vulnerabilidad en el cliente Cisco Webex Teams para Windows podría permitir que un atacante remoto autenticado haga que el cliente se bloquee, dando como resultado una condición de denegación de servicio (DoS). El atacante necesita una cuenta de desarrollador válida para aprovechar esta vulnerabilidad. La vulnerabilidad se debe a una validación de entrada insuficiente cuando se procesan tarjetas adaptativas recibidas. El atacante podría aprovechar esta vulnerabilidad enviando una tarjeta adaptable con contenido malicioso a un usuario existente del cliente Cisco Webex Teams para Windows. Una explotación con éxito podría permitir al atacante provocar que el cliente del usuario objetivo se bloquee continuamente.
