Apache 2.4.x < 2.4.12 Multiple Vulnerabilities

According to its banner, the version of Apache 2.4.x running on the remote host is prior to 2.4.12. It is, therefore, affected by the following vulnerabilities :

• A flaw exists in module mod_headers that can allow HTTP trailers to replace HTTP headers late during request processing, which a remote attacker can exploit to inject arbitrary headers. This can also cause some modules to function incorrectly or appear to function incorrectly. (CVE-2013-5704)

• A NULL pointer dereference flaw exists in module mod_cache. A remote attacker, using an empty HTTP Content-Type header, can exploit this vulnerability to crash a caching forward proxy configuration, resulting in a denial of service if using a threaded MPM. (CVE-2014-3581)

• A out-of-bounds memory read flaw exists in module mod_proxy_fcgi. An attacker, using a remote FastCGI server to send long response headers, can exploit this vulnerability to cause a denial of service by causing a buffer over-read. (CVE-2014-3583)

• A flaw exists in module mod_lua when handling a LuaAuthzProvider used in multiple Require directives with different arguments. An attacker can exploit this vulnerability to bypass intended access restrictions. (CVE-2014-8109)

Note that the scanner has not tested for these issues but has instead relied only on the application’s self-reported version number.
