  - SMB Server might be susceptible to relay attacks depending on the configuration. An attacker who
    successfully exploited these vulnerabilities could perform relay attacks and make the users subject to
    elevation of privilege attacks. The SMB Server already supports mechanisms for hardening against relay
    attacks: SMB Server signing SMB Server Extended Protection for Authentication (EPA) Microsoft is releasing
    this CVE to provide customers with audit capabilities to help them to assess their environment and to
    identify any potential device or software incompatibility issues before deploying SMB Server hardening
    measures that protect against relay attacks. If you have not already enabled SMB Server hardening
    measures, we advise customers to take the following actions to be protected from these relay attacks:
    Assess your environment by utilizing the audit capabilities that we are exposing in the September 2025
    security updates. See Support for Audit Events to deploy SMB Server HardeningSMB Server Signing & SMB
    Server EPA. Adopt appropriate SMB Server hardening measures. (CVE-2025-55234)

  - Improper restriction of communication channel to intended endpoints in Windows PowerShell allows an
    authorized attacker to elevate privileges locally. (CVE-2025-49734)

  - Stack-based buffer overflow in Windows Ancillary Function Driver for WinSock allows an authorized attacker
    to elevate privileges locally. (CVE-2025-54099)

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