Minor Subject: Recovering admin password can leave cleartext password on disk
Product(s) Affected: WebLogic Server
Threat level: Low
Someone with access to the server's filesystem may be able to read the admin password in certain cases.
The admin password may be obtained.
A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server. Viewlet updates have been made to correct this problem (see Section I). 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.
Only sites that have used the admin password reset mechanism as described on http://support.bea.com/askbea_soln/attachments/S-27131/81adminaccountreset_viewlet_swf.html before October 10th, 2005 are vulnerable. Sites that have not used that mechanism are not vulnerable or sites that have used it since October 10th, 2005 are not vulnerable.
Following the previously documented procedure to reset the admin password could result in the admin password being in cleartext in the domain directory.
This advisory resolves the issue by correcting the documentation so that the procedure now results in any new password being encrypted on the disk rather than in cleartext.
The following versions of WebLogic Server are affected by this vulnerability:
- WebLogic Server 8.1
II. SUGGESTED ACTION
Oracle strongly recommends the following course of actions.
- Sites which have used the above method to reset the admin password based on the instructions provided prior to October 10th, 2005 should be sure to change their admin password again via the console.
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: http://www.oracle.com/technology/software/products/ias/bea_main.html
Note: Information about securing WebLogic Server and WebLogic Express can be found at http://edocs.bea.com/wls/docs103/security.html. Specific lockdown information is provided at http://e-docs.bea.com/wls/docs103/lockdown/index.html. We strongly encourage you to review this documentation to ensure your server deployment is securely configured.
As a policy, if there are any security-related issues with any Oracle product, Oracle will distribute an advisory and instructions with the appropriate course of action. Because the security of your site, data, and code is our highest priority, we are committed to communicating all security-related issues clearly and openly.
