CVE-2024-27818 - iOS, iPadOS, and macOS Sonoma Vulnerability: Arbitrary Code Execution and App Termination

A vulnerability in Apple's iOS 17.5, iPadOS 17.5, and macOS Sonoma 14.5 operating systems has recently come to light. The issue, identified as CVE-2024-27818, could potentially allow an attacker to cause an unexpected app termination or even execute arbitrary code on an affected device. Apple has addressed this security concern by improving its memory handling in the aforementioned systems.

This long read aims to provide in-depth information about this vulnerability, including code snippets, links to original references, and details about the exploit. The text has been crafted in simple American English to make it accessible for all readers.

Exploit Details

The vulnerability existed due to improper handling of memory resources in the affected operating systems. A malicious attacker could carefully craft a payload that takes advantage of this memory handling flaw, leading to arbitrary code execution or unexpected app termination.

Code Snippet

Here's a simplified example of code that demonstrates how the memory handling issue could be exploited:

#include <iostream>
#include <string>

int main() {
    std::string malicious_payload = "EXAMPLE_PAYLOAD";

    // The attacker could exploit the vulnerability by overflowing the buffer
    char buffer[10];
    strcpy(buffer, malicious_payload.c_str());

    // This would lead to unexpected behavior, app termination, or arbitrary code execution
    std::cout << "Buffer: " << buffer << std::endl;

    return ;
}
