"According to its self-reported version, Cisco IOS-XE Software is affected by a vulnerability.

  - A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to
    perform an injection attack against an affected device. This vulnerability is due to insufficient input
    validation. An attacker could exploit this vulnerability by sending crafted input to the web UI. A
    successful exploit could allow the attacker to execute arbitrary Cisco IOS XE Software CLI commands with
    level 15 privileges. Note: This vulnerability is exploitable only if the attacker obtains the credentials
    for a Lobby Ambassador account. This account is not configured by default. (CVE-2023-20231)
