Descriptions

A vulnerability in Cisco Webex Teams could allow an unauthenticated, remote attacker to manipulate file names within the messaging interface. The vulnerability exists because the affected software mishandles character rendering. An attacker could exploit this vulnerability by sharing a file within the application interface. A successful exploit could allow the attacker to modify how the shared file name displays within the interface, which could allow the attacker to conduct phishing or spoofing attacks.

Una vulnerabilidad en Cisco Webex Teams, podría permitir a un atacante remoto no autenticado manipular nombres de archivos dentro de la interfaz de mensajería. La vulnerabilidad se presenta porque el software afectado maneja inapropiadamente la representación de caracteres. Un atacante podría explotar esta vulnerabilidad compartiendo un archivo dentro de la interfaz de la aplicación. Una explotación con éxito podría permitirle al atacante modificar cómo se muestra el nombre del archivo compartido dentro de la interfaz, lo que podría permitir al atacante realizar ataques de phishing o suplantación de identidad.
