Multiple cross-site scripting (XSS) vulnerabilities in BEA WebLogic Server and Express 8.1 through Service Pack 4, and 7.0 through Service Pack 6, allow remote attackers to inject arbitrary web script or HTML, and possibly gain administrative privileges, via the (1) j_username or (2) j_password parameters in the login page (LoginForm.jsp), (3) parameters to the error page in the Administration Console, (4) unknown vectors in the Server Console while the administrator has an active session to obtain the ADMINCONSOLESESSION cookie, or (5) an alternate vector in the Server Console that does not require an active session but also leaks the username and password.

The cluster cookie parsing code in BEA WebLogic Server 7.0 through Service Pack 5 attempts to contact any host or port specified in a cookie, even when it is not in the cluster, which allows remote attackers to cause a denial of service (cluster slowdown) via modified cookies.

Buffer overflow in BEA WebLogic Server and WebLogic Express 6.1 Service Pack 4 allows remote attackers to cause a denial of service (CPU consumption from thread looping).

BEA WebLogic Server and WebLogic Express 8.1 SP2 and SP3 allows users with the Monitor security role to "shrink or reset JDBC connection pools."

The UserLogin control in BEA WebLogic Portal 8.1 through Service Pack 3 prints the password to standard output when an incorrect login attempt is made, which could make it easier for attackers to guess the correct password.

The embedded LDAP server in BEA WebLogic Server and Express 8.1 through Service Pack 4, and 7.0 through Service Pack 5, allows remote anonymous binds, which may allow remote attackers to view user entries or cause a denial of service.

BEA WebLogic Server and WebLogic Express 8.1 through Service Pack 3 and 7.0 through Service Pack 5 does not properly handle when a security provider throws an exception, which may cause WebLogic to use incorrect identity for the thread, or to fail to audit security exceptions.

BEA WebLogic Server and WebLogic Express 6.1, 7.0, and 8.1, with RMI and anonymous admin lookup enabled, allows remote attackers to obtain configuration information by accessing MBeanHome via the Java Naming and Directory Interface (JNDI).

Race condition in BEA WebLogic Server and Express 5.1 through 7.0.0.1, when using in-memory session replication or replicated stateful session beans, causes the same buffer to be provided to two users, which could allow one user to see session data that was intended for another user.

BEA WebLogic Server and Express 6.0 through 7.0 does not properly restrict access to certain internal servlets that perform administrative functions, which allows remote attackers to read arbitrary files or execute arbitrary code.
