Improper input validation in Windows Server Update Service allows an unauthorized attacker to perform tampering over a network.

The remote Windows host is missing security update 5082063. It is, therefore, affected by multiple vulnerabilities

  - Double free in Windows IKE Extension allows an unauthorized attacker to execute code over a network.
    (CVE-2026-33824)

  - Protection mechanism failure in Windows Shell allows an unauthorized attacker to bypass a security feature     over a network. (CVE-2026-32225)

  - Use after free in Remote Desktop Client allows an unauthorized attacker to execute code over a network.
    (CVE-2026-32157)

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