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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Improper limitation of a pathname to a restricted directory ('path traversal') in .NET allows an     authorized attacker to elevate privileges locally. (CVE-2026-70161)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Out-of-bounds write in .NET allows an unauthorized attacker to execute code locally. (CVE-2026-62871,
    CVE-2026-70354)

  - Uncontrolled recursion in .NET allows an unauthorized attacker to deny service over a network.
    (CVE-2026-58280)

  - Origin validation error in .NET allows an unauthorized attacker to disclose information over a network.
    (CVE-2026-58649)

  - Integer overflow or wraparound in .NET allows an unauthorized attacker to elevate privileges locally.
    (CVE-2026-62886)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Out-of-bounds write in .NET allows an unauthorized attacker to execute code over a network.
    (CVE-2026-96235)

  - Uncontrolled recursion in .NET allows an unauthorized attacker to deny service over a network.
    (CVE-2026-58280)

  - Insertion of sensitive information into sent data in .NET allows an unauthorized attacker to disclose
    information over a network. (CVE-2026-66822)

  - Inefficient algorithmic complexity in .NET allows an unauthorized attacker to deny service over a network.
    (CVE-2026-69651)

  - Out-of-bounds write in .NET Framework allows an unauthorized attacker to execute code over a network.
    (CVE-2026-70007)

The Microsoft .NET Core SDK installations on the remote host are missing a security update. It is, therefore, affected by multiple vulnerabilities as referenced in the vendor advisory.

  - Inconsistent interpretation of http requests ('http request/response smuggling') in ASP.NET Core allows an     unauthorized attacker to bypass a security feature over a network. (CVE-2026-70188)

  - Inconsistent interpretation of http requests ('http request/response smuggling') in ASP.NET Core allows an     unauthorized attacker to perform tampering over a network. (CVE-2026-88092)

  - Heap-based buffer overflow in Microsoft QUIC allows an unauthorized attacker to execute code over a     network. (CVE-2026-105016)

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

The Microsoft Visual Studio Products are missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - Heap-based buffer overflow in Microsoft QUIC allows an unauthorized attacker to execute code over     a network. (CVE-2026-105016)

  - Inconsistent interpretation of http requests ('http request/response smuggling') in ASP.NET Core     allows an unauthorized attacker to perform tampering over a network. (CVE-2026-88092)
