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 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 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.

Weblogic.admin for BEA WebLogic Server and Express 7.0 and 7.0.0.1 displays the JDBCConnectionPoolRuntimeMBean password to the screen in cleartext, which allows attackers to read a user's password by physically observing ("shoulder surfing") the screen.

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 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.

BEA WebLogic Express and WebLogic Server 7.0 and 7.0.0.1, stores passwords in plaintext when a keystore is used to store a private key or trust certificate authorities, which allows local users to gain access.

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.

Cross-site scripting (XSS) vulnerability in InteractiveQuery.jsp for BEA WebLogic 8.1 and earlier allows remote attackers to inject malicious web script via the person parameter.

BEA WebLogic Server and Express, when using NodeManager to start servers, provides Operator users with privileges to overwrite usernames and passwords, which may allow Operators to gain Admin privileges.

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.
