.NET, .NET Framework, and Visual Studio Remote Code Execution Vulnerability

An update of the dotnet package has been released.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-242 advisory.

    .NET Denial of Service Vulnerability. (CVE-2023-21538)

    .NET, .NET Framework, and Visual Studio Remote Code Execution Vulnerability (CVE-2023-24895)

    .NET, .NET Framework, and Visual Studio Elevation of Privilege Vulnerability (CVE-2023-24936)

    .NET, .NET Framework, and Visual Studio Denial of Service Vulnerability (CVE-2023-29331)

    NuGet Client Remote Code Execution Vulnerability (CVE-2023-29337)

    .NET and Visual Studio Elevation of Privilege Vulnerability (CVE-2023-32032)

    .NET and Visual Studio Elevation of Privilege Vulnerability (CVE-2023-33135)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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 Framework installation on the remote host is missing a security update. It is, therefore, affected by multiple vulnerabilities, as follows:

  - A remote code execution vulnerability in the MSDIA SDK where corrupted PDBs can cause a heap overflow.
   (CVE-2023-24897)

  - A remote code execution vulnerability in WPF where the BAML offers other ways to instantiate types.
    (CVE-2023-21808)

  - A remote code execution vulnerability in the WPF XAML parser (CVE-2023-24895)

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

  - A remote code execution vulnerability in the MSDIA SDK where corrupted PDBs can cause heap overflow,     leading to a crash or remote code execution. (CVE-2023-24897)

  - A remote code execution vulnerability where specially crafted input to git apply -reject can lead to     controlled content writes at arbitrary locations. (CVE-2023-25652)

  - A spoofing vulnerability where Github localization messages refer to a hard-coded path instead of     respecting the runtime prefix that leads to out-of-bound memory writes and crashes. (CVE-2023-25815)

  - An Out-Of-Bounds Write Vulnerability in Autodesk FBX SDK version 2020 or prior may lead to code     execution through maliciously crafted FBX files or information disclosure. (CVE-2023-27909)

  - An information disclosure vulnerability where a user may be tricked into opening a malicious     FBX file. This may exploit a stack buffer overflow (CVE-2023-27910) or heap buffer overflow     (CVE-2023-27911) vulnerability in Autodesk FBX SDK 2020 or prior which may lead to remote code     execution. 

  - A remote code execution vulnerability where a configuration file containing a logic error results     in arbitrary configuration injection. (CVE-2023-29007)

  - A remote code execution vulnerability where the Git for Windows executable responsible for     implementing a SOCKS5 proxy is susceptible to picking up an untrusted configuration on multi-user     machines. (CVE-2023-29011)

  - A remote code execution vulnerability where the Git for Windows Git CMD program incorrectly     searches for a program upon startup, leading to silent arbitrary code execution. (CVE-2023-29012)

  - A remote code execution vulnerability in the .NET SDK during tool restore which can lead to an     elevation of privilege. (CVE-2023-33135)

  - An information disclosure vulnerability by the obj file parser in Visual Studio. (CVE-2023-33139)
