Wazuh is a free and open source platform used for threat prevention, detection, and response. A heap-based out-of-bounds WRITE occurs in decode_win_permissions, resulting in writing a NULL byte 2 bytes before the start of the buffer allocated to decoded_it. A compromised agent can potentially leverage this issue to perform remote code execution, by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can leverage this issue to potentially achieve remote code execution on the wazuh manager (the exploitability of this vulnerability depends on the specifics of the respective heap allocator). This vulnerability is fixed in 4.10.2.

CVE-2025-24016
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.

Wazuh is a free and open source platform used for threat prevention, detection, and response. It is capable of protecting workloads across on-premises, virtualized, containerized, and cloud-based environments. This vulnerability occurs when the system has weak privilege access, that allows an attacker to do privilege escalation. In this case the attacker is able to view agent list on Wazuh dashboard with no privilege access. This issue has been addressed in release version 4.9.1 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
