Apache HTTP Server Incorrect Authorization Vulnerability - CVE-2014-8109

mod_lua.c in the mod_lua module in the Apache HTTP Server 2.3.x and 2.4.x through 2.4.10 does not support an httpd configuration in which the same Lua authorization provider is used with different arguments within different contexts which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging multiple Require directives as demonstrated by a configuration that specifies authorization for one group to access a certain directory and authorization for a second group to access a second directory.
