Stack-based buffer overflow in Visual Studio allows an unauthorized attacker to execute code over a network.

The Microsoft .NET Core SDK installations on the remote host are missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - Improper authentication in ASP.NET Core allows an unauthorized attacker to elevate privileges over a     network. (CVE-2026-70175)

  - Improper access control in .NET allows an authorized attacker to elevate privileges locally.
    (CVE-2026-105544)

  - Deserialization of untrusted data in Visual Studio allows an unauthorized attacker to execute code over a     network. (CVE-2026-114151)

  - Stack-based buffer overflow in Visual Studio allows an unauthorized attacker to execute code over a     network. (CVE-2026-114152)

  - Time-of-check time-of-use (toctou) race condition in .NET allows an authorized attacker to elevate     privileges locally. (CVE-2026-114155)

  - Heap-based buffer overflow in Visual Studio allows an unauthorized attacker to execute code over a network.
    (CVE-2026-114158, CVE-2026-114159, CVE-2026-118745)

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

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

  - Stack-based buffer overflow in .NET allows an unauthorized attacker to deny service over a network.
    (CVE-2026-109475)

  - Deserialization of untrusted data in Visual Studio allows an unauthorized attacker to execute code over a     network. (CVE-2026-114151)

  - Stack-based buffer overflow in Visual Studio allows an unauthorized attacker to execute code over a     network. (CVE-2026-114152)

  - Heap-based buffer overflow in Visual Studio allows an unauthorized attacker to execute code over a network.
    (CVE-2026-114158, CVE-2026-114159, CVE-2026-118745)

  - Inefficient algorithmic complexity in .NET allows an unauthorized attacker to deny service over a network.
    (CVE-2026-118747)

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