Minor Subject: Changed passwords may show up in audit log
Product(s) Affected: WebLogic Server and WebLogic Express
Threat level: Medium
Changed passwords may be visible in the audit log on the server's file system.
Passwords may be exposed.
A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server. An upgrade is available to correct this problem (see Section II). Oracle treats potential security problems with a high degree of urgency and endeavors to take appropriate steps to help ensure the security of our customers' systems. 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.
All sites that have enabled configuration auditing are vulnerable.
If configuration auditing is enabled, changing a password triggers a configuration audit event which contains the old and new passwords in clear-text. The configuration audit event is written by the WebLogic Auditing provider to the DefaultAuditRecorder.log file on the server's file system in clear-text and may be written by other audit providers in clear-text to their audit store.
For more information about enabling configuration auditing, see
This patch resolves the issue by ensuring that passwords are not put into the configuration audit event.
The following versions of WebLogic Server and WebLogic Express are affected by this vulnerability
- WebLogic Server 8.1 released through Service Pack 4, on all platforms
II. SUGGESTED ACTION
Oracle strongly recommends the following course of actions.
WebLogic Server and WebLogic Express version 8.1
- Upgrade to service pack 5.
