Name of the Vulnerable Software and Affected Versions: Cisco IOS XE SD-WAN Software (affected versions not specified)

Description: A vulnerability in the role-based access control of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker with read-only privileges to obtain administrative privileges by using the console port when the device is in the default SD-WAN configuration.
