Descriptions

Multiple vulnerabilities in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the web services interface of an affected device. The vulnerabilities are due to insufficient validation of user-supplied input by the web services interface of an affected device. An attacker could exploit these vulnerabilities by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive, browser-based information. Note: These vulnerabilities affect only specific AnyConnect and WebVPN configurations. For more information, see the Vulnerable Products section.

Múltiples vulnerabilidades en la interfaz de servicios web de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podrían permitir a un atacante remoto no autenticado conducir ataques de tipo cross-site scripting (XSS) contra un usuario de la interfaz de servicios web de un dispositivo afectado. Las vulnerabilidades son debido a una comprobación insuficiente de la entrada suministrada por el usuario mediante la interfaz de servicios web de un dispositivo afectado. Un atacante podría explotar estas vulnerabilidades al persuadir a un usuario de la interfaz para que haga clic en un enlace diseñado. Una explotación con éxito podría permitir a un atacante ejecutar un código script arbitrario en el contexto de la interfaz o permitir a un atacante acceder a información confidencial basada en el navegador. Nota: Estas vulnerabilidades afectan solo a configuraciones específicas de AnyConnect y WebVPN. Para más información, consulte la sección Vulnerable Products

Cisco Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD) contain an insufficient input validation vulnerability for user-supplied input by the web services interface. Successful exploitation could allow an attacker to perform cross-site scripting (XSS) in the context of the interface or access sensitive browser-based information.
