CVE-2005-2963
HighSummary
The mod_auth_shadow module versions 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.
Risk Assessment
The organization is at risk of unauthorized access to resources protected by the require group directive, as users may bypass intended authentication mechanisms.
Recommendation
Update the mod_auth_shadow module to version 2.1 or later, which fixes this vulnerability. If an update is not possible, temporarily disable the AuthShadow option or avoid using the require group directive with this module.
