Unspecified vulnerability in BEA WebLogic Server 6.1 Gold through SP7, 7.0 Gold through SP7, and 8.1 Gold through SP4 allows remote attackers to cause a denial of service (server thread hang) via unspecified vectors.

The JMS Server in BEA WebLogic Server 6.1 through SP7, 7.0 through SP6, and 8.1 through SP5 enforces security access policies on the front end, which allows remote attackers to access protected queues via direct requests to the JMS back-end server.

The HttpClusterServlet and HttpProxyServlet in BEA WebLogic Express and WebLogic Server 6.1 through SP7, 7.0 through SP7, 8.1 through SP5, 9.0, and 9.1, when SecureProxy is enabled, may process "external requests on behalf of a system identity," which allows remote attackers to access administrative data or functionality.

Multiple cross-site scripting (XSS) vulnerabilities in BEA WebLogic Express and WebLogic Server 6.1 through SP7, 7.0 through SP7, 8.1 through SP5, 9.0 GA, and 9.1 GA allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The JMS Message Bridge in BEA WebLogic Server 7.0 through SP7 and 8.1 through Service Pack 6, when configured without a username and password, or when the connection URL is not defined, allows remote attackers to bypass the security access policy and "send unauthorized messages to a protected queue."

The embedded LDAP server in BEA WebLogic Express and WebLogic Server 7.0 through SP6, 8.1 through SP5, 9.0, and 9.1, when in certain configurations, does not limit or audit failed authentication attempts, which allows remote attackers to more easily conduct brute-force attacks against the administrator password, or flood the server with login attempts and cause a denial of service.

Unspecified vulnerability in the thread management in BEA WebLogic 7.0 through 7.0 SP6, 8.1 through 8.1 SP5, 9.0, and 9.1, when T3 authentication is used, allows remote attackers to cause a denial of service (thread and system hang) via unspecified "sequences of events."

BEA WebLogic 7.0 through 7.0 SP6, 8.1 through 8.1 SP4, and 9.0 initial release does not encrypt passwords stored in the JDBCDataSourceFactory MBean Properties, which allows local administrative users to read the cleartext password.

BEA Weblogic Server 8.1 through 8.1 SP4 does not properly validate client certificates when reusing cached connections, which allows remote attackers to obtain access via an untrusted X.509 certificate.

BEA WebLogic Server 8.1 through 8.1 SP5 stores cleartext data in a backup of config.xml after offline editing, which allows local users to obtain sensitive information by reading this backup file.
