Description
Wazuh is a free and open source platform used for threat prevention, detection, and response.
Starting in version 4.4.0 and prior to version 4.9.1, an unsafe deserialization vulnerability
allows for remote code execution on Wazuh servers. DistributedAPI parameters are serialized
as JSON and deserialized using `as_wazuh_object` (in `framework/wazuh/core/cluster/common.py`).
If an attacker manages to inject an unsanitized dictionary in DAPI request/response, they can
forge an unhandled exception (`__unhandled_exc__`) to evaluate arbitrary python code.
The vulnerability can be triggered by anybody with API access (compromised dashboard or Wazuh
servers in the cluster) or, in certain configurations, even by a compromised agent.
