A vulnerability in the web UI of Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, could allow an authenticated, remote attacker with read-only permissions to modify configurations and perform unauthorized actions on an affected system. This vulnerability exists because of a failure to redact sensitive information within device configurations and templates. An attacker could exploit this vulnerability by elevating their read-only permissions to those of a high-privileged user.
