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

  - A vulnerability in Application Quality of Experience (AppQoE) and Unified Threat Defense (UTD) on Cisco
    IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload
    unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to the
    mishandling of a crafted packet stream through the AppQoE or UTD application. An attacker could exploit
    this vulnerability by sending a crafted packet stream through an affected device. A successful exploit
    could allow the attacker to cause the device to reload, resulting in a DoS condition. (CVE-2023-20226)

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
