Security Advisories and Notifications


Security Advisory: (BEA05-72.01)

From: Oracle Corporation

Minor Subject: Upgrade and patch are available to disable users in Active Directory LDAP server

Product(s) Affected:
WebLogic Server and WebLogic Express

This security advisory (BEA05-72.01) contains corrected instructions for installing the wlSecurityProviders.jar file. There are no new or updated remedies in this advisory. Please disregard SECURITY ADVISORY BEA04-72.00, as this advisory, BEA05-72.01, supersedes it.

Threat level: Medium
The problem can only occur if a user has been deactivated in Active Directory LDAP server but not deleted and Active Directory LDAP server is being used as the authentication database.

Severity: High
Disabling an administrator's account still leaves the user with administrative privileges.

A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server and WebLogic Express. Patches are available to correct this problem (see Section II). Oracle 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

This vulnerability can occur when Active Directory LDAP server is used as the authentication database and a user account is disabled but not deleted.

This vulnerability causes the disabled user to continue to be able to log in to WebLogic Server with all of the privileges they had before becoming disabled.

This advisory resolves the issue by patching WebLogic Server so that it now does not allow a disabled user to log in.

The following versions of WebLogic Server are affected by this vulnerability:
  • WebLogic Server 8.1, released through Service Pack 2, on all platforms when Active Directory LDAP server is used for authentication
  • WebLogic Server 7.0, released through Service Pack 5, on all platforms when Active Directory LDAP server is used for authentication

II. SUGGESTED ACTION

Oracle strongly recommends the following course of actions.

WebLogic Server 8.1
Upgrade to WebLogic Server 8.1 Service Pack 3.
WebLogic Server 7.0

Perform the following steps:
  1. Upgrade to WebLogic Server 7.0 Service Pack 5
  2. Download the file #7825247 from OracleMetaLink as per the instructions below:
    • Select the Patches and Updates tab after logging in to OracleMetaLink.
    • Click Simple Search.
    • In the Search By field, select Patch Number from the list.
    • Enter the patch number. The patch number may be different for different product releases and platforms.
    • Select the platform (or choose generic as applicable)
    • Click Go.
    • Click Download to download the patch.
  3. Rename this file wlSecurityProviders.jar
  4. Move the existing wlSecurityProviders.jar file to another directory. Typically, this file is found in the \releases\70sp5\weblogic700\server\lib\mbeantypes directory.
  5. Copy the new wlSecurityProviders.jar file to the directory in which you found the existing wlSecurityProviders.jar file.
WebLogic Server 7.0 Service Pack 6 will include the functionality in this patch.
