Security Advisory: (BEA03-14.06)

From: Oracle Corporation

Subject: SECURITY ADVISORY (BEA03-14.06)

Minor Subject: Patch available for DOS attack

Product(s) Affected: BEA WebLogic Server and Express

Threat Level: Low

Severity: High

This security advisory (BEA03-14.06) contains a corrected list of the WebLogic Server versions affected. There are no new or updated remedies in this Advisory. Please disregard SECURITY ADVISORY BEA02-14.00, BEA02-14.01, BEA02-14.02, BEA02-14.03, BEA02-14.04 and BEA03-14.05, as this advisory, BEA03-14.06, supersedes them.

A consultant with KPMG 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 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

A potential security vulnerability was discovered that could allow users to hang BEA WebLogic Server through specific HTTP requests.

The following BEA WebLogic Server and Express releases are affected by this vulnerability
  • Version: BEA WebLogic Server and Express 5.1.x, 6.0.x, 6.1.x and 7.0 on Microsoft NT or Windows 2000.

CAUSE

This vulnerability may occur when certain HTTP/S requests cause the WebLogic Server to process without halting. This may result in a hung condition in which the server cannot respond to additional requests. While this is an edge case, a user aware of this vulnerability could exploit it to hang the server. There is no configuration to prevent this exploitation.

BEA WebLogic Server and Express version 5.1 on Microsoft NT or Windows 2000.
