Positive Technologies (AI Summary)

CVSS v3.1

8.8

High

Base vector

AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: Wazuh versions 4.0.0 through 4.0.3

Description: The issue allows authenticated users to execute arbitrary code with administrative privileges via the "/manager/files" API endpoint. This is possible due to incomplete input validation on the "/manager/files" API, which can be exploited by an authenticated user to inject arbitrary code within the API service script.

Recommendations: For versions 4.0.0 through 4.0.3, update to a version outside of this range to mitigate the risk of arbitrary code execution. As a temporary workaround, consider restricting access to the "/manager/files" API endpoint to minimize the risk of exploitation.
