Description

David Herselman has reported a security issue in the mod_auth_shadow module for Apache, which potentially can be exploited by malicious people to bypass certain security restrictions.

The problem is that the mod_auth_shadow authentication scheme is automatically used when using the "require group" directive in a ".htaccess" file, which may be different than the intended HTTP authentication scheme.


Solution
Update to version 1.5 or 2.1.
