Security Advisories and Notifications


Security Advisory: (BEA02-13.00)

From: Oracle Corporation

Minor Subject: Patch available for unintended permissions

Product(s) Affected: BEA WebLogic Server and Express

BEA has identified a problem that could potentially cause a security vulnerability in certain versions of BEA WebLogic Server and Express on all platforms. Patches are available to correct these problems (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

Recently, a potential security vulnerability was discovered that could allow code unintended permissions. This vulnerability could allow a user to gain access as the "system" user from malicious code running inside WebLogic Server. Since the system-level user is generally given permission in most access control lists in a default WebLogic installation, this malicious code could obtain unintended permissions.

The following BEA WebLogic Server and Express releases are affected by this vulnerability
  • Version: BEA WebLogic Server and Express 4.5.x, 5.1.x, 6.0.x and 6.1.x.

CAUSE

This vulnerability creates the potential for unprivileged code that has been installed in the server as part of an application (in a jar, war, rar or ear file) to become the "system" user. Once becoming the system user the code can perform any operation in the server that the administrator is allowed to perform.


II. SUGGESTED ACTION

Oracle strongly recommends the following course of actions:

Apply the appropriate Service Pack below:
  • Version: BEA WebLogic Server and Express version 6.1 standalone and as part of BEA WebLogic Enterprise 6.1 on all OS platforms
    • Action: Apply Service Pack 2 or higher

  • Version: BEA WebLogic Server and Express version 6.0 standalone and as part of BEA WebLogic Enterprise 6.0 on all OS platforms
    • Action: Apply Service Pack 2 and download and apply the patch #7822612 from OracleMetaLink as per the instructions below:
      • Select the Patches and Updates tab after logging in to OracleMetaLink.

      • Select the platform (or choose generic as applicable)
      • Click Go.
      • Click Download to download the patch.

  • Version: BEA WebLogic Server and Express version 5.1 standalone and as part of BEA WebLogic Enterprise 5.1.x on all OS platforms
    • Action: Apply Service Pack 11 or higher

  • Version: BEA WebLogic Server and Express 4.5.2 on all OS platforms
    • Action: Apply Service Pack 2 and download and apply the patch #7822600 from OracleMetaLink as per the instructions below:

  • Version: BEA WebLogic Server and Express 4.5.1 on all OS platforms
    • Action: Apply Service Pack 15 and download and apply the patch #7822582 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 16 becomes available, you can use that jar instead of Service Pack 1 and this patch.
A further step should be taken as an additional precaution:

Audit all code running on your WebLogic Server to verify that there is no malicious code of this type running. This is a recommended procedure for all applications. Please consult the guide at http://e-docs.bea.com/wls/docs61/security/lockdown.html
