TITLE

Cisco FXOS and NX-OS Software input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-004656

DESCRIPTION

A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause the SNMP application to leak system memory, which could cause an affected device to restart unexpectedly. The vulnerability is due to improper error handling when processing inbound SNMP packets. An attacker could exploit this vulnerability by sending multiple crafted SNMP packets to an affected device. A successful exploit could allow the attacker to cause the SNMP application to leak system memory because of an improperly handled error condition during packet processing. Over time, this memory leak could cause the SNMP application to restart multiple times, leading to a system-level restart and a denial of service (DoS) condition. Cisco FXOS and NX-OS The software contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Cisco FXOS and NX-OS Softwares are prone to an denial-of-service vulnerability An attacker can exploit this issue to restart the affected system, denying service to legitimate users. This issue is being tracked by Cisco bug IDs CSCvc58707, CSCvd45657, CSCvn19457, CSCvn19463, CSCvn19464, CSCvn19465, CSCvn19468 and CSCvn19483. Cisco Firepower 4100 Series, etc. are all products of Cisco (Cisco). Cisco Firepower 4100 Series is a 4100 series firewall device. Cisco FXOS Software is a set of firewall software that runs on Cisco security appliances. Cisco Nexus 3000 Series Switches is a 3000 series switch. Cisco MDS 9000 Series Multilayer Switches is a MDS 9000 series multilayer switch. Cisco NX-OS Software is a set of data center-level operating system software used by switches. The vulnerability stems from the failure of the network system or product to properly validate the input data. The following products and versions are affected: Cisco Firepower 4100 Series; Firepower 9300 Security Appliances; MDS 9000 Series Multilayer Switches; Nexus 1000V Switch for Microsoft Hyper-V; Nexus 1000V Switch for VMware vSphere; Nexus 3000 Series Switches; 5500 Platform Switches; Nexus 5600 Platform Switches; Nexus 6000 Series Switches; Nexus 7000 Series Switches; Nexus 7700 Series Switches; Nexus 9000 Series Fabric Switches in Application Centric Infrastructure
