The Microsoft .NET Framework installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - Allocation of resources without limits or throttling in .NET allows an unauthorized attacker to deny     service over a network. (CVE-2026-47302)

  - Stack-based buffer overflow in .NET Framework allows an unauthorized attacker to deny service over a     network. (CVE-2026-50527)

  - Protection mechanism failure in .NET Framework allows an unauthorized attacker to execute code locally.
    (CVE-2026-50646)

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