BEA WebLogic Server and Express 7.0 and 7.0.0.1 stores certain secrets concerning password encryption insecurely in config.xml, filerealm.properties, and weblogic-rar.xml, which allows local users to learn those secrets and decrypt passwords.

The default CredentialMapper for BEA WebLogic Server and Express 7.0 and 7.0.0.1 stores passwords in cleartext on disk, which allows local users to extract passwords.

BEA WebLogic Server 6.1, 7.0 and 7.0.0.1, when routing messages to a JMS target domain that is inaccessible, may leak the user's password when it throws a ResourceAllocationException.

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.

BEA WebLogic Server and Express 7.0 and 7.0.0.1, when using "memory" session persistence for web applications, does not clear authentication information when a web application is redeployed, which could allow users of that application to gain access without having to re-authenticate.

BEA WebLogic Server and Express 6.1 through 7.0.0.1 buffers HTTP requests in a way that can cause BEA to send the same response for two different HTTP requests, which could allow remote attackers to obtain sensitive information that was intended for other users.

BEA WebLogic Server and Express 7.0 and 7.0.0.1, when running Servlets and Enterprise JavaBeans (EJB) on more than one server, will remove the security constraints and roles on all servers for any Servlets or EJB that are used by an application that is undeployed on one server, which could allow remote attackers to conduct unauthorized activities in violation of the intended restrictions.

An undocumented extension for the Servlet mappings in the Servlet 2.3 specification, when upgrading to WebLogic Server and Express 7.0 Service Pack 1 from BEA WebLogic Server and Express 6.0 through 7.0.0.1, does not prepend a "/" character in certain URL patterns, which prevents the proper enforcement of role mappings and policies in applications that use the extension.
