Security Advisories and Notifications


Subject: Security Advisory (BEA08-194.00)
From: Oracle Corporation
Minor Subject: A non-authorized user may be able to send messages to a protected distributed queue
Product(s) Affected: WebLogic Server

Threat level: Medium
Under certain circumstances, an attacker could bypass the security policies defined on a protected distributed queue.

Severity: High
Unauthorized messages could be injected into a protected distributed queue.

A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server. Patches and upgrades 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

The distributed queue feature in WebLogic JMS provides higher availability in a clustered environment. If a JMS client sends a message to a distributed queue and encounters a problem with one member of that distributed queue (the member is down, the member exceeds its quota, access denied, etc), internally the JMS subsystem will retry another member of the same distributed destination. In certain configurations, an unauthorized user is able to send messages to a secure distributed queue.

This advisory corrects the problem and ensures that the correct user identity is maintained.
