Description

This security bulletin contains information about 1 security vulnerability.


1) Race condition (CVE-ID: CVE-2016-9256)

The vulnerability allows a remote authenticated user to gain elevated privileges on the target system.

The weakness exists due to race condition during the enforcement of permissions by the iControl component when permissions are assigned to a user and the role_map feature is not reloaded between the time permissions are changed and the user's next change request. A remote attacker can gain elevated privileges and conduct further attacks.

Successful exploitation of the vulnerability may result in access to the system.
