Security Advisories and Notifications


Security Advisory: (BEA03-32.00)

From: Oracle Corporation

Minor Subject: Patch available to prevent unauthorized access to the console

Product(s) Affected: WebLogic Server and Express

Threat level: low

Severity: low

Recently a developer at Nihon Unisys identified a problem that could potentially cause a security vulnerability in certain versions of WebLogic Server and Express. Patches are available to correct this problem (see section II below). BEA treats such possibilities with the highest degree of urgency and does everything possible to ensure the security of all customer assets. As a result, we strongly suggest the following action:

      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 below.


I. ADVISORY

This vulnerability can occur when a firewall, connection filter or other mechanism is used to restrict access to the console and MSI (managed server independence) is used. In some circumstances, the console can be accessed through the managed server's listen port. Typically, this will only affect the single managed server's configuration, but if the managed server is on the same machine as the administration server or is sharing the config.xml over a network share, the resulting updates made via the managed server's console can affect the entire domain.

The following versions of WebLogic Server and Express are affected by this vulnerability
  • WebLogic Server and Express 7.0 and 7.0.0.1 on all platforms.

II. SUGGESTED ACTION

Oracle strongly recommends the following course of actions:

WebLogic Server and Express 7.0 and 7.0.0.1:
  • Upgrade to Service Pack 2, and download and apply the patch #7824680 from OracleMetaLink as per the instructions below:
    • Select the Patches and Updates tab after logging in to OracleMetaLink.
    • Click Simple Search.
    • In the Search By field, select Patch Number from the list.
    • Enter the patch number. The patch number may be different for different product releases and platforms.
    • Select the platform (or choose generic as applicable)
    • Click Go.
    • Click Download to download the patch.
  • When Service Pack 3 becomes available, you can use that Service Pack instead of Service Pack 2 and this patch.
