A vulnerability in the web UI of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to gain read and write access to information that is stored on an affected system.
Does this matter?
Lower severity and a low EPSS score (0.88%). Track it; it rarely justifies an emergency change on its own.
