Security Advisories and Notifications


Security Advisory: (BEA05-95.00)

From: Oracle Corporation

Minor Subject: Exporting security policies from one operating system and importing to another operating system can lead to servlets being unprotected.

Product(s) Affected: WebLogic Server and WebLogic Express

Threat level: Low
A system administrator who exports security policies from one operating system and then imports them to a different operating system may leave servlets unprotected.

Severity: Medium
Servlets could be unprotected.

A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server. Documentation updates are 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.

I. Advisory

All sites are susceptible to this vulnerability. The vulnerability only occurs when system administrators export and import security policies between operating systems. By default, the context path and uri arguments for the WebLogic URLResource (used to protect servlets) are stored in lowercase on Windows and mixed case on UNIX. As a result, if you define security roles and policies in a domain on one operating system, export them, and then import them to a domain on an operating system with different case handling, the security roles and policies may not work correctly. The end result is that Web Application pages that are protected on one operating system may not be protected on a different operating system.

This issue was resolved by updating Managing WebLogic Server to caution system administrators who are exporting and importing policies between different operating systems to the risks involved. The information is available from:

WebLogic Server 7.0
http://edocs.bea.com/wls/docs70/secmanage/ldap.html#1100437

WebLogic Server 8.1
http://edocs.bea.com/wls/docs81/secmanage/security_data_migration.html#1187466

The following versions of WebLogic Server and WebLogic Express are affected by this vulnerability

  • WebLogic Server 8.1, on all platforms.
  • WebLogic Server 7.0, on all platforms.

II. SUGGESTED ACTION


Oracle strongly recommends the following course of actions.

If you have exported and imported security policies between operating systems, review the appropriate documentation links above to ensure that security roles and policies are entered properly.
