Associated Vulnerability

Title:Remote code execution in Wazuh server (CVE-2025-24016)
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 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.

Description

A critical Remote Code Execution (RCE) vulnerability exists in Wazuh server versions >= 4.4.0 and < 4.9.1. The vulnerability occurs due to unsafe deserialization in the wazuh-manager package, specifically in the DistributedAPI where parameters are serialized as JSON and deserialized using as_wazuh_object in the framework/wazuh/core/cluster/common.py file. An attacker with API access can exploit this vulnerability by injecting an unsanitized dictionary into DAPI requests, leading to arbitrary Python code execution.
