The authentication module for Apache 2.0.40 through 2.0.45 on Unix does not properly handle threads safely when using the crypt_r or crypt functions, which allows remote attackers to cause a denial of service (failed Basic authentication with valid usernames and passwords) when a threaded MPM is used.

Security readout for executives and security teams

CVE-2003-0189 is a legacy Apache HTTP Server flaw that can make Basic authentication fail or disrupt access on affected Unix servers. The issue only applies to Apache 2.0.40 through 2.0.45 when a threaded MPM is used. It is mainly a business-continuity risk for old, unsupported systems still exposed to users or the internet. Exposure is limited to Unix systems running Apache HTTP Server 2.0.40-2.0.45 with Basic authentication and a threaded MPM. Modern Apache versions are not identified as affected in the supplied sources. Prioritize only if asset inventory finds affected Apache 2.0.x servers. For most organizations this is a legacy cleanup item, but exposed unsupported servers should be upgraded because the impact is user-facing service disruption. Mitigation focus: Identify any Apache HTTP Server 2.0.40 through 2.0.45 deployments on Unix.; Upgrade affected Apache installations to Apache 2.0.46 or later per vendor guidance.; Apply operating system vendor packages where Apache is managed by a Linux distribution..
