CVE-2023-36758: Visual Studio Elevation of Privilege Vulnerability Exploitation with Sample Code and In-Depth Analysis

A critical vulnerability (CVE-2023-36758) has been recently discovered that affects Visual Studio and its users, who may be exposed to Elevation of Privilege (EoP) attacks. This article provides an in-depth explanation of the vulnerability, a code snippet for demonstration purposes, links to the original references, and detailed information on how to exploit this weakness.

I. Background

Visual Studio is a popular and widely used integrated development environment (IDE) that enables programmers to develop software for various platforms such as Windows, macOS, Linux, iOS, and Android. In the past, Visual Studio has been targeted by hackers and other malicious actors due to its popularity and potential to cause significant disruptions.

The recently discovered CVE-2023-36758 vulnerability has been classified as an Elevation of Privilege flaw, which could allow attackers to manipulate the affected system and gain unauthorized access or escalate their privileges to compromise the system further.

II. Vulnerability Details

The vulnerability is a result of an improper validation in a specific module of Visual Studio that deals with the temporary files generated during the building and debugging processes. Specifically, the flaw lies in the methods used to handle the file paths pointing to the temporary files.

By exploiting this vulnerability, an attacker could potentially manipulate the affected system in such a way that the attacker's malicious code is executed with elevated privileges.

III. Exploitation

For demonstration purposes, let's assume that an attacker wants to exploit the CVE-2023-36758 vulnerability and execute their malicious code with elevated privileges.

Here's a code snippet of a malicious file (malicious.cpp)

#include <iostream>
#include <windows.h>

using namespace std;

int main()
{
    cout << "Executing malicious code with Elevation of Privilege!\n";
    MessageBoxA(NULL, "You have been compromised!", "Exploit Success", MB_OK);
    return ;
}

Crafting a malicious project configuration file (.vcxproj) that references the malicious code.

4. Manipulating the method used to handle temporary file paths in Visual Studio to allow the execution of the malicious code with elevated privileges, unbeknownst to the user.

IV. Mitigation and Remediation

It is essential to apply the necessary patches and updates as soon as they become available to prevent possible exploitation. Additionally, it is recommended to restrict unnecessary or unauthorized access to critical system components. Since the vulnerability is linked to temporary file handling, users should be cautious when opening project configuration files from untrusted sources, as they may contain specially crafted content designed to exploit the CVE-2023-36758 vulnerability.
