Weak authentication in Windows Active Directory Certificate Services allows an authorized attacker to elevate privileges over a network.

The remote Windows host is missing security update 5055557. It is, therefore, affected by multiple vulnerabilities

  - Use after free in Windows Win32K - GRFX allows an unauthorized attacker to elevate privileges over a     network. (CVE-2025-26687)

  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2025-27481)   
  - An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges. (CVE-2025-27740)

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