Security Advisories and Notifications


Security Advisory: (BEA01-10.00)

From: Oracle Corporation

Minor Subject: Patch Available for TDomain gateway Vulnerability in BEA Tuxedo

Product(s) Affected: BEA Tuxedo version 6.3, 6.4, 6.5, 6.5.1, 7.1, 7.1.1, BEA WLE 4.2, 5.0, and 5.1

Threat Level: Medium

It has come to our attention that an anomaly in BEA Tuxedo and BEA WebLogic Enterprise could be used to expose a potential security vulnerability. This condition affects BEA Tuxedo version 6.3, 6.4, 6.5, 6.5.1, 7.1, 7.1.1 and BEA WebLogic Enterprise version 4.2, 5.0, and 5.1 on all supported platforms. 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

A vulnerability has been identified in BEA Tuxedo and BEA WebLogic Enterprise versions that may potentially allow unauthorized access to services in a Tuxedo domain through a TDomain gateway. This is because a fault exists in the TDomain gateway whereby, when using SECURITY=APP_PW or SECURITY=DM_PW in the Domain gateway's dmconfig file, the gateway permits a remote domain to submit requests (for example, object invocations, TPCALL and TPCONNECT) before completing any of the connection authorization checks which verify the remote domain's identity. This affects only TDomain gateways.

The TDomain gateway is open to attack only from systems spoofing the TDomains protocol. It is not open to attack from other TDomain gateways; when the standard TDomain gateway is running on both sides of the connection, the authorization checks are properly completed and do not permit any requests to be submitted before the connection establishment authorization checks have been completed.


II. SUGGESTED ACTION

Oracle strongly recommends the following course of actions:

  • Version: BEA Tuxedo 6.3, 6.4, 6.5, 6.5.1, 7.1, 7.1.1, and BEA WebLogic Enterprise 4.2, 5.0, and 5.1

    For any Tuxedo or WebLogic Enterprise node which is offering services via a TDomain gateway with the dmconfig SECURITY parameter set to APP_PW or DM_PW: Identify the rolling patch number for your Tuxedo or WebLogic Enterprise system release from the following list and apply that or a higher numbered rolling patch.


  • Release Rolling Patch Number
    • Tuxedo 6.3 183
    • Tuxedo 6.4 294
    • Tuxedo 6.5 and 6.5.1  243
    • Tuxedo 7.1 and 7.1.1 57
    • WLE 4.2 36
    • WLE 5.0 32
    • WLE 5.1 22
PLEASE NOTE: When using rolling patch 57 or later for Tuxedo version 7.1 (and 7.1.1) with TDomain security (that is, when the dmconfig SECURITY parameter is set to APP_PW or DM_PW), you can not interoperate with Tuxedo 7.1 systems without the rolling patch installed. This is because the TDomain connection security protocol used between two Tuxedo version 7.1 (or above) systems has been revised. Interoperation when the dmconfig SECURITY parameter is set to NONE is unaffected, as is interoperation with releases prior to 7.1.
