Security Advisories and Notifications


Security Advisory: (BEA05-76.00)

From: Oracle Corporation

Minor Subject: WebLogic Server fails to audit and correctly handle exceptions generated by security providers.

Product(s) Affected: WebLogic Server and WebLogic Express

Threat level: Medium
Certain WebLogic Server security provider exceptions may result in the security framework behaving errantly. Depending on the server configuration and the security provider implementation, these exceptions can potentially be generated by a knowledgeable remote user.

Severity: High
Incorrect identity may be allowed on a thread and/or auditing may not be performed in all cases.

A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server. An upgrade will correct this problem (see Section II). BEA System treats potential security problems with the highest degree of urgency and does everything possible to ensure the security of all customer assets. 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.
This vulnerability occurs in both WebLogic Server and WebLogic Express. Subsequent references in this advisory to WebLogic Server are intended to encompass both products.

I. Advisory

All sites are susceptible to this vulnerability. It can occur anytime a security provider has an internal error and throws an exception. This vulnerability may lead to incorrect identity on the thread or a failure to audit security exceptions.

The issue was resolved by changing the way exceptions generated by security providers are handled such that thread identity is ensured to be correct and that auditing is performed correctly.

The following versions of WebLogic Server are affected by this vulnerability:
  • WebLogic Server 8.1 through Service Pack 3 on all platforms
  • WebLogic Server 7.0 through Service Pack 5 on all platforms

II. SUGGESTED ACTION


Oracle strongly recommends the following course of actions:

WebLogic Server 8.1
Upgrade to WebLogic Server 8.1 Service Pack 4
WebLogic Server 7.0
Upgrade to WebLogic Server 7.0 Service Pack 6
