Security Advisories and Notifications

Security Advisory: (BEA04-73.00)

From: Oracle Corporation

Minor Subject: Documentation is available to configure the server for encryption of administrative data.

Product(s) Affected: WebLogic Server and WebLogic Express

Threat level: Low
Only users on the local network with the ability to "snoop" packets can exploit this vulnerability.

Severity: High
A successful exploit might reveal sensitive data (for example, the password of the system administrator) or allow server configurations to be tampered with.

A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server and WebLogic Express. Patches are available to correct this problem (see Section II). Oracle treats potential security problems with the highest degree of urgency and does everything possible to ensure the security of all customer assets. As a result, Oracle strongly suggests the following actions:
I. Read the following advisory.

II. Apply the suggested action.

III. If you know of any additional users interested in future security advisories, please forward them the registration instructions included in this advisory.
This vulnerability occurs in both WebLogic Server and WebLogic Express. Throughout the rest of this advisory, references to WebLogic Server apply to both products.


This vulnerability can occur when the administration port is not enabled and an attacker has the ability to snoop packets on the local network. A firewall, if properly configured and vulnerability-free, can protect against this attack. Note that Oracle does not recommend relying on firewalls for the protection of WebLogic Server data.

This vulnerability causes sensitive data and configuration information to be communicated using clear-text protocols rather than encrypted protocols (typically SSL). A clever attacker on the local network can potentially monitor and even replace the configuration information (for example, disable security).

This advisory resolves the issue by updating the documentation to clearly state the risks of not enabling the administration port.

The following versions of WebLogic Server are affected by this vulnerability
  • WebLogic Server 8.1 on all platforms
  • WebLogic Server 7.0 on all platforms.


Oracle strongly recommends the following course of actions:
