Descriptions

A vulnerability in the XML parser code of Cisco Firepower Device Manager On-Box software could allow an authenticated, remote attacker to cause an affected system to become unstable or reload. The vulnerability is due to insufficient hardening of the XML parser configuration. An attacker could exploit this vulnerability in multiple ways using a malicious file: An attacker with administrative privileges could upload a malicious XML file on the system and cause the XML code to parse the malicious file. An attacker with Clientless Secure Sockets Layer (SSL) VPN access could exploit this vulnerability by sending a crafted XML file. A successful exploit would allow the attacker to crash the XML parser process, which could cause system instability, memory exhaustion, and in some cases lead to a reload of the affected system.

Una vulnerabilidad en el código del analizador XML del software Cisco Firepower Device Manager On-Box, podría permitir a un atacante remoto autenticado causar que un sistema afectado se vuelva inestable o se sobrecargue. La vulnerabilidad es debido a un endurecimiento (hardening) insuficiente de la configuración del analizador XML. Un atacante podría explotar esta vulnerabilidad de múltiples maneras usando un archivo malicioso: Un atacante con privilegios administrativos podría cargar un archivo XML malicioso sobre el sistema y causar que el código XML analice el archivo malicioso. Un atacante con acceso VPN Secure Sockets Layer (SSL) sin cliente podría explotar esta vulnerabilidad mediante el envío de un archivo XML diseñado. Una explotación con éxito permitiría a un atacante bloquear el proceso del analizador XML, lo que podría causar inestabilidad del sistema, agotamiento de la memoria y, en algunos casos conllevar a una recarga del sistema afectado.
