9.9 criticalCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:HCVE-2025-24016
Critical (9.9) in Wazuh Wazuh Server. In CISA KEV since 2025-06-10. EPSS 94% chance of exploitation in the next 30 days. Fixed in github.com/wazuh/wazuh 4.9.1, 4.9.1+incompatible.
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.
