BEA WebLogic Server 6.1 through 6.1 SP7, 7.0 through 7.0 SP6, 8.1 through 8.1 SP5, and 9.0 allows remote attackers to cause a denial of service (server hang) via certain requests that cause muxer threads to block when processing error pages.

BEA WebLogic Server 6.1 through 6.1 SP7, and 7.0 through 7.0 SP7 allows remote attackers to cause a denial of service (disk consumption) via requests containing malformed headers, which cause a large amount of data to be written to the server log.

The HTTP handlers in BEA WebLogic Server 9.0, 8.1 up to SP5, 7.0 up to SP6, and 6.1 up to SP7 stores the username and password in cleartext in the WebLogic Server log when access to a web application or protected JWS fails, which allows attackers to gain privileges.

BEA WebLogic Server 8.1 up to SP4, 7.0 up to SP6, and 6.1 up to SP7 displays the internal IP address of the WebLogic server in the WebLogic Server Administration Console, which allows remote authenticated administrators to determine the address.

Unspecified vulnerability in BEA WebLogic Server 9.1 and 9.0, 8.1 through SP5, 7.0 through SP6, and 6.1 through SP7 allows untrusted applications to obtain private server keys.

Multiple vulnerabilities in BEA WebLogic Server 8.1 through SP4, 7.0 through SP6, and 6.1 through SP7 leak sensitive information to remote attackers, including (1) DNS and IP addresses to address to T3 clients, (2) internal sensitive information using GetIORServlet, (3) certain "server details" in exceptions when invalid XML is provided, and (4) a stack trace in a SOAP fault.

BEA WebLogic Server 6.1 SP7 and earlier allows remote attackers to read arbitrary files via unknown attack vectors related to a "default internal servlet" accessed through HTTP.

BEA WebLogic Server and WebLogic Express 8.1 SP4 and earlier, 7.0 SP6 and earlier, and WebLogic Server 6.1 SP7 and earlier allow remote attackers to cause a denial of service (memory exhaustion) via crafted non-canonicalized XML documents.

BEA WebLogic Server and WebLogic Express 8.1 through SP4, 7.0 through SP6, and 6.1 through SP7 allows remote authenticated guest users to read the server log and obtain sensitive configuration information.

By design, BEA WebLogic Server and WebLogic Express 7.0 and 6.1, when creating multiple domains from the same WebLogic instance on the same machine, allows administrators of any created domain to access other created domains, which could allow administrators to gain privileges that were not intended.
