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.","cwes":["CWE-502"],"vendors":[{"vendor":"cloudflare","status":"blocks","basis":"claimed","firstOn":"2025-08-11","firstIsNew":true,"daysToRule":182,"daysAtMost":null,"freePlan":false,"claims":[{"id":"d7c0237271440fd431af15d1f9277847f358e28a177b9883adedf949ec7c6869","cve_id":"CVE-2025-24016","vendor":"cloudflare","product":"Cloudflare Managed Ruleset","rule_id":"7fdb3c7bc7b74703aeef4ab240ec2fda","rule_name":"Wazuh Server - Remote Code Execution - CVE:CVE-2025-24016","change":"new","default_action":"Block","published_on":"2025-08-11","source_url":"https://developers.cloudflare.com/changelog/post/2025-08-11-waf-release/","source_title":"WAF Release - 2025-08-11","excerpt":"Wazuh Server - Remote Code Execution - CVE:CVE-2025-24016.
