FKIE_CVE-2026-74038

Vulnerability from fkie_nvd - Published: 2026-08-18 18:19 - Updated: 2026-10-22 22:10
Severity
7.1 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H
Summary
Wazuh 4.0.0 before 4.14.6 contains a path traversal vulnerability that allows unauthenticated remote attackers to cause denial of service by enrolling an agent with a dot-sequence name such as ".." through the enrollment port. Attackers exploit insufficient validation in OS_IsValidName() and unsafe path concatenation in delete_diff() to resolve the traversal to the parent queue directory, causing its subdirectories to be removed and stopping all Wazuh services requiring manual recovery.
