[原文]BEA WebLogic Server and WebLogic Express 7.0 through SP5 and 8.1 through SP2 does not enforce site restrictions for starting and stopping servers for users in the Admin and Operator security roles, which allows unauthorized users to cause a denial of service (service shutdown).
BEA WebLogic Express and Server contains a flaw that may allow unprivilege Admin and Operator security roles start and stop server. The issue is due to the start and stop policies for Admin and Operator security roles aren't properly enforced. It is possible that the flaw may allow a local attacker to arbitrarily start and stop the webserver, resulting in a loss of availability.
Upgrade to WebLogic Server and WebLogic Express version 8.1 SP2 or WebLogic Server and WebLogic Express version 7.0 SP5 or higher, as they have been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
