What is CVE-2014-8109?
CVE-2014-8109 is a medium-severity authentication bypass vulnerability in Apache Http Server, published on 29 Dec 2014. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
