Privilege escalation via local-first permission override
Published Apr 28, 2023 · Updated Jan 30, 2025
Incorrect default permissions in Lenovo XClarity Controller allow remote authenticated users to gain elevated XCC privileges through LDAP logins. The authorization path lets matching local-account permissions override the user's Active Directory permissions instead of enforcing the directory grant. Exploitation requires a valid XCC account, LDAP authentication and authorization, and the “Local First, then LDAP” login order.
