Descriptions
A vulnerability in the Secure Sockets Layer (SSL) packet reassembly functionality of the detection engine in Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause the detection engine to consume excessive system memory on an affected device, which could cause a denial of service (DoS) condition. The vulnerability is due to the affected software improperly handling changes to SSL connection states. An attacker could exploit this vulnerability by sending crafted SSL connections through an affected device. A successful exploit could allow the attacker to cause the detection engine to consume excessive system memory on the affected device, which could cause a DoS condition. The device may need to be reloaded manually to recover from this condition. This vulnerability affects Cisco Firepower System Software Releases 6.0.0 and later, running on any of the following Cisco products: Adaptive Security Appliance (ASA) 5500-X Series Firewalls with FirePOWER Services, Adaptive Security Appliance (ASA) 5500-X Series Next-Generation Firewalls, Advanced Malware Protection (AMP) for Networks, 7000 Series Appliances, Advanced Malware Protection (AMP) for Networks, 8000 Series Appliances, Firepower 4100 Series Appliances, FirePOWER 7000 Series Appliances, FirePOWER 8000 Series Appliances, Firepower 9300 Series Security Appliances, Firepower Threat Defense for Integrated Services Routers (ISRs), Firepower Threat Defense Virtual for VMware, Industrial Security Appliance 3000, Sourcefire 3D System Appliances. Cisco Bug IDs: CSCve23031.
Una vulnerabilidad en la funcionalidad SSL (Secure Sockets Layer) de reensamblado de paquetes del motor de detección en Cisco Firepower System Software podría permitir que un atacante remoto no autenticado provoque que el motor de detección consuma memoria del sistema en exceso en un dispositivo afectado, lo que podría provocar una condición de denegación de servicio (DoS). La vulnerabilidad se debe a que el software afectado gestiona incorrectamente los cambios en los estados de conexión SSL. Un atacante podría explotar esta vulnerabilidad enviando conexiones SSL manipuladas a través de un dispositivo afectado. Una explotación exitosa podría permitir al atacante provocar que el motor de detección consuma memoria del sistema en exceso en el dispositivo afectado, lo que podría provocar una denegación de servicio (DoS). El dispositivo podría necesitar volver a cargarse manualmente para que se recupere. Esta vulnerabilidad afecta a Cisco Firepower System Software Releases 6.0.0 y posteriores, ejecutándose en cualquiera de estos productos de Cisco: Adaptive Security Appliance (ASA) 5500-X Series Firewalls con FirePOWER Services, Adaptive Security Appliance (ASA) 5500-X Series Next-Generation Firewalls, Advanced Malware Protection (AMP) for Networks, 7000 Series Appliances, Advanced Malware Protection (AMP) for Networks, 8000 Series Appliances, Firepower 4100 Series Appliances, FirePOWER 7000 Series Appliances, FirePOWER 8000 Series Appliances, Firepower 9300 Series Security Appliances, Firepower Threat Defense for Integrated Services Routers (ISRs), Firepower Threat Defense Virtual for VMware, Industrial Security Appliance 3000 y Sourcefire 3D System Appliances. Cisco Bug IDs: CSCve23031.
