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 elevate their privileges from low to high and perform actions as a high-privileged user. This vulnerability exists because sensitive session information is recorded in audit logs. An attacker could exploit this vulnerability by elevating their read-only permissions in Cisco Catalyst SD-WAN Manager to those of a high-privileged user.
