CVE-2020-3375

A vulnerability in Cisco SD-WAN Solution Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to gain access to information that they are not authorized to access, make changes to the system that they are not authorized to make, and execute commands on an affected system with privileges of the root user.
