  - A vulnerability in the NETCONF feature of Cisco IOS XE Software could allow an authenticated, remote
    attacker to elevate privileges to root on an affected device. This vulnerability is due to improper
    validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted input
    over NETCONF to an affected device. A successful exploit could allow the attacker to elevate privileges
    from Administrator to root. (CVE-2024-20278)
