Descriptions
A vulnerability 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 retrieve memory contents on an affected device, which could lead to the disclosure of confidential information. The vulnerability is due to a buffer tracking issue when the software parses invalid URLs that are requested from the web services interface. An attacker could exploit this vulnerability by sending a crafted GET request to the web services interface. A successful exploit could allow the attacker to retrieve memory contents, which could lead to the disclosure of confidential information. Note: This vulnerability affects only specific AnyConnect and WebVPN configurations. For more information, see the Vulnerable Products section.
Una vulnerabilidad en la interfaz de servicios web del Cisco Adaptive Security Appliance (ASA) Software y el Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado recuperar contenido de la memoria sobre un dispositivo afectado, lo que podría conducir a la divulgación de información confidencial . La vulnerabilidad es debido a un problema de rastreo del búfer cuando el software analiza las URL no válidas que son solicitadas desde la interfaz de servicios web. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición GET diseñada hacia la interfaz de servicios web. Una explotación con éxito podría permitir a un atacante recuperar el contenido de la memoria, lo que podría conllevar a la divulgación de información confidencial. Nota: Esta vulnerabilidad solo afecta a configuraciones específicas de AnyConnect y WebVPN. Para más información, consulte la sección Vulnerable Products.
