Minor Subject: Upgrade and patches are available to protect password.
Product(s) Affected: WebLogic Server and WebLogic Express
Threat level: Low
Users must have access to the WebLogic Server Administrative Console to see the password.
An administrative account can be compromised.
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.This vulnerability occurs in both WebLogic Server and WebLogic Express. Throughout the rest of this advisory, references to WebLogic Server apply to both products.
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 can occur when booting WebLogic Server on the Linux operating system and entering the password used to boot the server via the WebLogic Administrative Console. The password should not be echoed but in some cases it is.
This advisory patch resolves the issue in two ways. First, it fixes the problem by adding no-echo capabilities on the Linux operating system. Second, it changes the default behavior of the server such that if no-echo cannot be enabled the server will not boot when in Production mode. See the README file in the patch for further documentation.

- WebLogic Server 8.1, released through Service Pack 2, on Linux
