A vulnerability in the web-based management interface of Cisco IOS XE New Generation Wireless Controller (NGWC) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device. The vulnerability is due to insufficient CSRF protections for the web-based management interface of the affected software. An attacker could exploit this vulnerability by persuading a user of the interface to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on an affected device by using a web browser and with the privileges of the user. Una vulnerabilidad en la interfaz de administración basada en la web del Controlador inalámbrico de nueva generación Cisco IOS XE (NGWC) podría permitir que un atacante remoto no autenticado realice un ataque de falsificación de solicitud entre sitios (CSRF) y realice acciones arbitrarias en un dispositivo afectado. • https://www.exploit-db.com/exploits/47153 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190821-iosxe-ngwc-csrf • CWE-352: Cross-Site Request Forgery (CSRF) •

A vulnerability in the Internet Group Management Protocol (IGMP) packet-processing functionality of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to exhaust buffers on an affected device, resulting in a denial of service (DoS) condition, aka a Memory Leak. The vulnerability is due to the affected software insufficiently processing IGMP Membership Query packets that are sent to an affected device. An attacker could exploit this vulnerability by sending a large number of IGMP Membership Query packets, which contain certain values, to an affected device. A successful exploit could allow the attacker to exhaust buffers on the affected device, resulting in a DoS condition that requires the device to be reloaded manually. This vulnerability affects: Cisco Catalyst 4500 Switches with Supervisor Engine 8-E, if they are running Cisco IOS XE Software Release 3.x.x.E and IP multicast routing is configured; Cisco devices that are running Cisco IOS XE Software Release 16.x, if IP multicast routing is configured. • http://www.securityfocus.com/bid/103568 http://www.securitytracker.com/id/1040592 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-igmp • CWE-399: Resource Management Errors CWE-772: Missing Release of Resource after Effective Lifetime •

A vulnerability in the IP Version 4 (IPv4) processing code of Cisco IOS XE Software running on Cisco Catalyst 3850 and Cisco Catalyst 3650 Series Switches could allow an unauthenticated, remote attacker to cause high CPU utilization, traceback messages, or a reload of an affected device that leads to a denial of service (DoS) condition. The vulnerability is due to incorrect processing of certain IPv4 packets. An attacker could exploit this vulnerability by sending specific IPv4 packets to an IPv4 address on an affected device. A successful exploit could allow the attacker to cause high CPU utilization, traceback messages, or a reload of the affected device that leads to a DoS condition. If the switch does not reboot when under attack, it would require manual intervention to reload the device. • http://www.securityfocus.com/bid/103563 http://www.securitytracker.com/id/1040588 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-ipv4 • CWE-19: Data Processing Errors •
