An authorization bypass exists in Lenovo XClarity Controller (XCC) versions prior to 3.08 CDI340V, 3.01 TEI392O, 1.71 PSI328N where a valid authenticated user with lesser privileges may be granted read-only access to higher-privileged information if 1) “LDAP Authentication Only with Local Authorization” mode is configured and used by XCC, and 2) a lesser privileged user logs into XCC within 1 minute of a higher privileged user logging out. The authorization bypass does not exist when “Local Authentication and Authorization” or “LDAP Authentication and Authorization” modes are configured and used by XCC.
Solution:
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
