Minor Subject: The local file system may be accessed remotely by a user granted the Admin security role.
Product(s) Affected: WebLogic Server and WebLogic Express
Threat level: Medium
Files on a local file system may be accessed by a remote user with Admin privileges.
Security-sensitive information on the local file system may be read by a remote user with Admin privileges.
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 are susceptible to this vulnerability. The vulnerability is exploited via an HTTP or HTTPS connection to the Administration server by a WebLogic Server system administrator. A remote user granted the Admin security role with HTTP access to the server may be able to access files on the server's file system by accessing an internal servlet. The patch or upgrade resolves the issue by restricting the access of the internal servlet to only the specific set of WebLogic files required for it to function.
The following versions of WebLogic Server and WebLogic Express are affected by this vulnerability
- WebLogic Server 8.1 released through Service Pack 3, 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 4.
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:
