"The version of Palo Alto GlobalProtect App installed on the remote Windows host is 6.0.x prior to 6.0.15, 6.2.x prior
to 6.2.8-h13, or 6.3.x prior to 6.3.3-h14. It is, therefore, affected by multiple vulnerabilities collectively known
as Global Un-Protect:

  - Local privilege escalation vulnerabilities enable a local user to escalate their privileges to
    NT AUTHORITY\SYSTEM. (CVE-2026-0299)

  - A buffer overflow vulnerability enables a man-in-the-middle (MitM) attacker or a rogue gateway to disrupt
    system processes and potentially execute arbitrary code with SYSTEM privileges. (CVE-2026-0297)

  - An improper input validation vulnerability in the Windows Pre-Logon Access Provider (PLAP) component enables
    a man-in-the-middle (MitM) attacker to execute arbitrary code with SYSTEM privileges. (CVE-2026-0298)

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