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 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.

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).

The Web Services fat client for BEA WebLogic Server and Express 7.0 SP4 and earlier, when using 2-way SSL and multiple certificates to connect to the same URL, may use the incorrect identity after the first connection, which could allow users to gain privileges.

BEA WebLogic Server and Express 8.1, SP1 and earlier, stores the administrator password in cleartext in config.xml, which allows local users to gain privileges.

The default configuration of BEA WebLogic Server and Express 8.1 SP2 and earlier, 7.0 SP4 and earlier, 6.1 through SP6, and 5.1 through SP13 responds to the HTTP TRACE request, which can allow remote attackers to steal information using cross-site tracing (XST) attacks in applications that are vulnerable to cross-site scripting.

BEA WebLogic Server and WebLogic Express 6.1, 7.0, and 8.1, when using Remote Method Invocation (RMI) over Internet Inter-ORB Protocol (IIOP), does not properly handle when multiple logins for different users coming from the same client, which could cause an "unexpected user identity" to be used in an RMI call.

BEA WebLogic Server and WebLogic Express 7.0 through 7.0 Service Pack 4, and 8.1 through 8.1 Service Pack 2, allows attackers to obtain the username and password for booting the server by directly accessing certain internal methods.

The URL pattern matching feature in BEA WebLogic Server 6.x matches illegal patterns ending in "*" as wildcards as if they were the legal "/*" pattern, which could cause WebLogic 7.x to allow remote attackers to bypass intended access restrictions because the illegal patterns are properly rejected.

The remove method in a stateful Enterprise JavaBean (EJB) in BEA WebLogic Server and WebLogic Express version 8.1 through SP2, 7.0 through SP4, and 6.1 through SP6, does not properly check EJB permissions before unexporting a bean, which allows remote authenticated users to remove EJB objects from remote views before the security exception is thrown.

The WebLogic Authentication provider for BEA WebLogic Server and WebLogic Express 8.1 through SP2 and 7.0 through SP4 does not properly clear member relationships when a group is deleted, which can cause a new group with the same name to have the members of the old group, which allows group members to gain privileges.

BEA WebLogic Server and WebLogic Express 7.0 through SP5 and 8.1 through SP2, when editing weblogic.xml using WebLogic Builder or the SecurityRoleAssignmentMBean.toXML method, inadvertently removes security-role-assignment tags when weblogic.xml does not have a principal-name tag, which can remove intended access restrictions for the associated web application.

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 Server and WebLogic Express 8.1 SP2 and earlier, and 7.0 SP4 and earlier, when using 2-way SSL with a custom trust manager, may accept a certificate chain even if the trust manager rejects it, which allows remote attackers to spoof other users or servers.

BEA WebLogic Server and WebLogic Express version 8.1 up to SP2, 7.0 up to SP4, and 6.1 up to SP6 may store the database username and password for an untargeted JDBC connection pool in plaintext in config.xml, which allows local users to gain privileges.

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 version 7.0 SP3 may follow certain code execution paths that result in an incorrect current user, such as in the frequent use of JNDI initial contexts, which could allow remote authenticated users to gain privileges.

BEA WebLogic Server proxy plugin for BEA Weblogic Express and Server 6.1 through 8.1 SP 1 allows remote attackers to cause a denial of service (proxy plugin crash) via a malformed URL.

BEA WebLogic Express and Server 7.0 through 8.1 SP 1, under certain circumstances when a request to use T3 over SSL (t3s) is made to the insecure T3 port, may use a non-SSL connection for the communication, which could allow attackers to sniff sessions.

The Node Manager for BEA WebLogic Express and Server 6.1 through 8.1 SP 1 allows remote attackers to cause a denial of service (Node Manager crash) via malformed data to the Node Manager's port, as demonstrated by nmap.
