TITLE

Cisco SD-WAN Solution Software exhaustion vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2020-008332

DESCRIPTION

A vulnerability in Cisco SD-WAN Solution Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper validation of fields in Cisco SD-WAN peering messages that are encapsulated in UDP packets. An attacker could exploit this vulnerability by sending crafted UDP messages to the targeted system. A successful exploit could allow the attacker to cause services on the device to fail, resulting in a DoS condition that could impact the targeted device and other devices that depend on it. Cisco SD-WAN Solution is a set of network expansion solutions of Cisco (Cisco). The following products and versions are affected: Cisco SD-WAN vBond Orchestrator; SD-WAN vEdge 100 Series Routers; SD-WAN vEdge 1000 Series Routers; SD-WAN vEdge 2000 Series Routers; SD-WAN vEdge 5000 Series Routers; SD-WAN vEdge Cloud Router; SD-WAN vManage; SD-WAN vSmart Controller
