Certain configurations of BEA WebLogic Server and WebLogic Express 9.0, 8.1 through SP5, and 7.0 through SP6, when connection filters are enabled, cause the server to run more slowly, which makes it easier for remote attackers to cause a denial of service (server slowdown).

BEA WebLogic Server and WebLogic Express 8.1 through SP4 and 7.0 through SP6 does not properly handle when servlets use relative forwarding, which allows remote attackers to cause a denial of service (slowdown) via unknown attack vectors that cause "looping stack overflow errors."

Multiple unspecified vulnerabilities in BEA WebLogic Server and WebLogic Express 8.1 through SP4, 7.0 through SP6, and 6.1 through SP7 allow remote attackers to access MBean attributes or cause an unspecified denial of service via unknown attack vectors.

HTTP request smuggling vulnerability in BEA WebLogic Server and WebLogic Express 8.1 SP4 and earlier, 7.0 SP6 and earlier, and 6.1 SP7 and earlier allows remote attackers to inject arbitrary HTTP headers via unspecified attack vectors.

BEA WebLogic Server and WebLogic Express 8.1 SP4 and earlier, and 7.0 SP6 and earlier, in certain "heavy usage" scenarios, report incorrect severity levels for an audit event, which might allow attackers to perform unauthorized actions and avoid detection.

BEA WebLogic Server and WebLogic Express 9.0, 8.1, and 7.0 lock out the admin user account after multiple incorrect password guesses, which allows remote attackers who know or guess the admin account name to cause a denial of service (blocked admin logins).

BEA WebLogic Server and WebLogic Express 8.1 SP4 and earlier, and 7.0 SP6 and earlier, might allow local users to gain privileges by using the run-as deployment descriptor element to change the privileges of a web application or EJB from the Deployer security role to the Admin security role.

BEA WebLogic Server and WebLogic Express 8.1 SP4 and earlier, and 7.0 SP5 and earlier, do not encrypt multicast traffic, which might allow remote attackers to read sensitive cluster synchronization messages by sniffing the multicast traffic.

BEA WebLogic Server and WebLogic Express 8.1 SP4 and earlier, 7.0 SP6 and earlier, and 6.1 SP7 and earlier, when Internet Inter-ORB Protocol (IIOP) is used, sometimes include a password in an exception message that is sent to a client or stored in a log file, which might allow remote attackers to perform unauthorized actions.

BEA WebLogic Server and WebLogic Express 8.1 through SP4, 7.0 through SP6, and 6.1 through SP7, when a Java client application creates an SSL connection to the server after it has already created an insecure connection, will use the insecure connection, which allows remote attackers to sniff the connection.
