Security Advisories and Notifications


Security Advisory: (BEA03-38.00)

From: Oracle Corporation

Minor Subject: Patch available to prevent BEA Tuxedo Administration Console vulnerability

Product(s) Affected: Tuxedo and WebLogic Enterprise

Threat level: Low

Severity: Medium

Recently Corsaire Limited identified a problem that could potentially cause security vulnerability in BEA Tuxedo and WebLogic Enterprise. 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


BEA Tuxedo administration console is a CGI application. The administration console accepts a few startup arguments such as a PATH to an initialization file. These arguments are not checked for formatting and validity. The administration console processes these arguments that could lead to following exploitations:
  • Remote file disclosure: By providing various path values in this argument, it is possible to use the administration console to determine the existence of a file.
  • Denial of service: An attacker could provide a device name instead of a valid file as one of the arguments. This may lead to a valid user's attempt to login into administration console to hang. This may also affect stability of the server running administration console processes.
  • Cross-Site Scripting (XSS) - Administration Console repeats the argument back if it is an invalid file name. By using a carefully constructed filename, code such as JavaScript can be executed within a user's context. This user can be tricked into clicking on an URL that will unintentionally share his/her sensitive information with an attacker.

The vulnerability can affect both Tuxedo and WebLogic Enterprise installations.

The following versions of Tuxedo and WebLogic Enterprise are affected by this vulnerability
  • Tuxedo 8.1, Tuxedo 8.0, Tuxedo 7.1, Tuxedo 6.5, Tuxedo 6.4, Tuxedo 6.3, all platforms.
  • WebLogic Enterprise 5.1, WebLogic Enterprise 5.0.1 and WebLogic Enterprise 4.2, all platforms.

II. SUGGESTED ACTION


Oracle strongly recommends restricting access to administrative tools such as Tuxedo Administration Console to trusted domains only. In addition, you could take following course of action:

Tuxedo 8.1
  • Apply Rolling Patch 62 or later.
For all other releases
  • Upgrade to Tuxedo 8.1, or
  • Contact Oracle Customer Support to request a fix for the release you are using.
