6.4.3-b8, or 6.5.x prior to 6.5.3-b15. It is, therefore, affected by multiple vulnerabilities:

  - A denial of service (DoS) vulnerability in Palo Alto Networks Prisma SD-WAN ION devices enables an
    unauthenticated attacker in a network adjacent to a Prisma SD-WAN ION device to cause a system disruption by
    sending a specially crafted IPv6 packet. (CVE-2026-0243)

  - An improper certificate validation vulnerability in the Palo Alto Networks Prisma SD-WAN ION enables
    man-in-the-middle (MitM) attacker to impersonate the controller. (CVE-2026-0244)

Note that Nessus has not tested for these issues but has instead relied only on the device's self-reported version
number.");
