Security Advisories and Notifications


Security Advisory: (BEA03-40.00)

From: Oracle Corporation

Minor Subject: Patches available to prevent unintended use of nonencrypted connection

Product(s) Affected: WebLogic Server and Express

Threat level: Low
The problem can only occur with an incorrect configuration.

Severity: Low
The attack requires someone to be able to be snooping the network at the appropriate time.

Recently a problem was identified 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 an attempt is made to access WebLogic Server using SSL over T3 but a non-secure server port is specified in the URL. For example, if 7001 is the non-SSL port and 7002 is the SSL port, then the problem occurs when the URL"t3s://myhost:7001" is used instead of "t3s://myhost:7002". Under certain circumstances this incorrect specification will cause a non-SSL connection to be used even though "t3s" was requested. With the application of the remedy below, an exception will always be thrown when attempting to use SSL on a non-secure port.

Only sites that have applications that use the T3S protocol (T3 over SSL) are vulnerable to this problem. If you do not have an application that uses T3S directly then this vulnerability does not affect you.

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
  • WebLogic Server and Express 8.1 on all platforms

II. SUGGESTED ACTION


Oracle strongly recommends the following course of actions:

WebLogic Server and Express 8.1
  • Upgrade to Service Pack 1 and download and apply the patch #7823333 from OracleMetaLink as per the instructions below:
    • Select the Patches and Updates tab after logging in to OracleMetaLink.
    • Click Simple Search.

    • 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.

    When Service Pack 2 becomes available, you can use that Service Pack instead of Service Pack 1 and this patch.

WebLogic Server and Express 7.0 and 7.0.0.1
  • Upgrade to Service Pack 4 and download and apply the patch #7823320 from OracleMetaLink as per the instructions below:
