What is CVE-2022-20696?

CVE-2022-20696 is a high-severity missing authorization vulnerability in Cisco Catalyst Sd-Wan Manager, published on 8 Sep 2022. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

A vulnerability in the binding configuration of Cisco SD-WAN vManage Software containers could allow an unauthenticated, adjacent attacker who has access to the VPN0 logical network to also access the messaging service ports on an affected system. This vulnerability exists because the messaging server container ports on an affected system lack sufficient protection mechanisms. An attacker could exploit this vulnerability by connecting to the messaging service ports of the affected system. To exploit this vulnerability, the attacker must be able to send network traffic to interfaces within the VPN0 logical network. This network may be restricted to protect logical or physical adjacent networks, depending on device deployment configuration. A successful exploit could allow the attacker to view and inject messages into the messaging service, which can cause configuration changes or cause the system to reload.
