Security Advisories and Notifications


Subject: Security Advisory (BEA07-181.00)
From: Oracle Corporation
Minor Subject: BEA Plumtree Foundation search facility allows an unauthenticated guest user to search for user objects.
Product(s) Affected: BEA Plumtree Foundation and BEA AquaLogic Interaction

Threat level: Medium
Through a simple HTTP request or by exercising the basic search form functionality, the guest user can view user objects and user properties.

Severity: Medium
An attacker could potentially obtain sensitive information on unsecured user accounts or properties. This information, in conjunction with common brute-force password attacks, could be used to randomly guess user passwords, and thereby compromise user accounts.

A problem was identified that could potentially cause a security vulnerability in certain versions of the BEA Plumtree Foundation and BEA AquaLogic Interaction. Simple configuration changes 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

BEA Plumtree Foundation and AquaLogic Interaction allow guest logins. By default these guest users have access to potentially sensitive data, especially user data. While we know of no critical data that is accessible by a guest user, it is possible that this data can be used in conjunction with data acquired by other means or in conjunction with other types of attacks to compromise the system.

This advisory provides instructions that assist in securing a portal such that guest users do not have read access to portal user objects.

Impact and CVSS Ratings:

CVSS Severity Score: 4.7 (Medium)
Attack Range (AV): Remote
Attack Complexity (AC): Low
Authentication Level (Au): Not Required
Impact Type: Partial Integrity and Confidentiality impact
Vulnerability Type: Information Disclosure
CVSS Base Score Vector: (AV:R/AC:L/Au:NR/C:P/I:P/A:N/B:N)

The following versions of BEA Plumtree Foundation and BEA AquaLogic Interaction are affected by this vulnerability

  • BEA Plumtree Foundation 6.0 through service pack 1 on all platforms.
  • BEA AquaLogic Interaction 6.1 through service pack 1, on all platforms.

II. SUGGESTED ACTION

Oracle strongly recommends the following course of actions.

BEA Plumtree Foundation 6.0, AquaLogic Interaction 6.1, AquaLogic Interaction 6.1 MP1

  1. Use the following steps to correct this issue:

  2. Login to your portal using an account with admin privilege.

  3. Click on the Administration tab to display the Admin Objects Directory.

  4. Determine the administrative folders that contain portal user objects. (For example, determine which administrative folders are specified as target folders when importing users into the portal.)

  5. Select those administrative folders and click on the Security icon.

  6. On the “Edit Security” page, set all “Guest” user account(s) to have access privilege “None” using the drop-down list. (Note: in some cases, the “Guest” user account(s) will not be explicitly listed on the “Edit Security” page, but will be incorporated via the “Everyone” group. As a general best practice, we recommend removing the “Everyone” group from access to user objects and replacing it as required with the explicit “Everyone in <Auth Source>” group(s) and explicit “Guest” user(s). Be aware when removing the “Everyone” group from administrative folders that the “Guest” user(s) must have Read access to the Authentication Source objects in order to display them for selection in the login page. Please consult http://edocs.bea.com/alui/ali/docs61/admin/users.html#wp1052992 for more details on setting user access privileges and requirements.)

  7. Click “Finish” to save your security changes.

  8. Run the Search Update Agent to refresh the search index with the updated security.
