.NET and Visual Studio Remote Code Execution Vulnerability

An update of the dotnet package has been released.

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)

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

A remote code execution vulnerability exists in ASP.NET Core 6.0 < 6.0.14 and ASP.NET Core 7.0 < 7.0.3. This vulnerability exists due to how .NET reads debugging symbols, where reading a malicious symbols file may result in remote code execution. An unauthenticated, local attacker can exploit this, to bypass authentication and execute arbitrary commands.

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

  - A denial of service (DoS) vulnerability. (CVE-2023-21722)

  - A remote code execution vulnerability. (CVE-2023-21808)

The remote Windows host is missing security update 5022838. It is, therefore, affected by multiple vulnerabilities

  - Windows iSCSI Discovery Service Remote Code Execution Vulnerability (CVE-2023-21803)

  - Microsoft PostScript Printer Driver Remote Code Execution Vulnerability (CVE-2023-21684, CVE-2023-21801)

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

  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication     and execute unauthorized arbitrary commands. (CVE-2023-21808, CVE-2023-21815, CVE-2023-23381)

  - An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
    (CVE-2023-21566)

  - A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected     component to deny system or application services. (CVE-2023-21567)
