Synopsis

The remote device is missing a vendor-supplied security patch

Description

A denial of service (DoS) vulnerability exists in Cisco SD-WAN Solution Software due to improper validation of fields in Cisco SD-WAN peering messages that are encapsulated in UDP packets. An unauthenticated, remote attacker can exploit this issue, by sending crafted UDP messages to the targeted system, to cause the process to fail resulting in a DoS condition that could impact the targeted device and other devices that depend on it.
