# Wazuh is a free and open source platform used for threat prevention, detection, and response

Wazuh Server has a deserialization flaw in which untrusted data is parsed unsafely. An attacker who can reach the server can run code on it.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Wazuh Wazuh Server affected ? fixed ?
- vendor:wazuh affected >= 4.4.0, < 4.9.1 fixed 4.9.1

## Fix

Apply the vendor mitigation; CISA says to follow vendor instructions or discontinue use if none exist. Fixed version: unknown.

## From the sources

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 a 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. Version 4.9.1 contains a fix.
