Minor Subject: Sensitive attributes may be stored in clear-text after offline configuration
Product(s) Affected: WebLogic Server and WebLogic Express
Threat level: Low
A configuration backup file may contain sensitive attributes in clear text.
Sensitive information may be stored in clear-text on the hard disk.
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.
This vulnerability can occur if an administrator edits the config.xml file offline with clear text values for sensitive attributes. At restart time, WebLogic Server saved a backup file preserving the clear text values provided for these sensitive attributes.
This advisory resolves this issue by interrupting the server restart when clear-text fields are detected to allow the administrator to select the appropriate corrective action.
The following versions of WebLogic Server and WebLogic Express are affected by this vulnerability:
- WebLogic Server 8.1 released through Service Pack 5, 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 6.
Oracle strongly suggests that customers apply the remedies recommended in all our security advisories. Oracle also urges customers to apply every Service/Maintenance Pack as they are released. Service/Maintenance Packs include a roll-up of all bug fixes for each version of the product, as well as each of the prior Service/Maintenance Packs. Service/Maintenance Packs and information about them can be found at:
