The mod_auth_shadow module 1.0 through 1.5 and 2.0 for Apache with AuthShadow enabled uses shadow authentication for all locations that use the require group directive, even when other authentication mechanisms are specified, which might allow remote authenticated users to bypass security restrictions.

Security readout for executives and security teams

CVE-2005-2963 is an authorization bypass in Apache mod_auth_shadow. On affected legacy deployments, protected areas using group requirements may be checked against shadow authentication even when another authentication method was configured. A remote authenticated user might reach content or functions they should not access. Exposure is likely limited to old Apache installations running mod_auth_shadow with AuthShadow enabled and require group directives. Modern environments are unlikely to be affected unless they retain legacy packages or copied Apache authentication configurations. Treat this as a targeted legacy exposure review, not an internet-wide emergency. Prioritize systems that still run old Apache authentication modules or host sensitive internal applications behind group-based access controls. Mitigation focus: Apply relevant vendor security updates from Debian, Mandriva, or the current distribution maintainer.; Remove or disable mod_auth_shadow if shadow-backed Apache authentication is no longer required.; Review Apache locations using AuthShadow and require group for unintended authentication behavior..
