Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-863.

Summary

Wazuh versions from 4.6.0 before 4.14.8 contain an authentication bypass in the security.update_user function, where the reserved user guard and password policy sit inside a falsy truthiness check. A delegated user administrator can send an empty password to the user update endpoint, which takes over the wazuh superuser account and lets the attacker authenticate with empty credentials. The flaw is classified as CWE-863 (Incorrect Authorization).

Description from the CNA

Wazuh versions from 4.6.0 before 4.14.8 contain an authentication bypass vulnerability where security.update_user places the reserved user guard and password policy inside a falsy truthiness check. A delegated user administrator can send an empty password to the user update endpoint, bypassing the reserved user guard to take over the wazuh superuser account and authenticate with empty credentials.
