From: Oracle Corporation

Minor Subject: WebLogic Server HTTP handlers log username and password on failure

Product(s) Affected: WebLogic Server

Threat level: Low
Requires local file access to the WebLogic Server log.

Severity: Low
Failed username and password are visible in WebLogic Server log.

A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server. Patches and an upgrade are available to correct this problem (see Section II). Oracle treats potential security problems with a high degree of urgency and endeavors to take appropriate steps to help ensure the security of our customers' systems. As a result, Oracle strongly suggests the following actions:
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 included in this advisory.

I. Advisory

All sites that that use WebLogic Server HTTP handlers and that host protected Java Web Service (JWS) or web apps are affected by this issue.

If access to a protected JWS or web app fails, the username and password used in the access attempt may be logged to the server log. This can result in the password (either valid or invalid) being visible in clear text in the WebLogic Server log.

This patch resolves the issue by ensuring that the username and password are removed from the failure message written to the log.

The following versions of WebLogic Server are affected by this vulnerability:

  • WebLogic Server 9.0, on all platforms
  • WebLogic Server 8.1 released through service pack 5, on all platforms
  • WebLogic Server 7.0 released through service pack 6, on all platforms
  • WebLogic Server 6.1 released through service pack 7, on all platforms
