Apache 2.4.x < 2.4.12 Multiple Vulnerabilities

high Web Application Scanning Plugin ID 98907
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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.


Upgrade to Apache version 2.4.12 or later. Alternatively, ensure that the affected modules are not in use.
