Apache 2.4.x < 2.4.12 Multiple Vulnerabilities
medium Nessus Plugin ID 81126
Language:
Synopsis
The remote web server is affected by multiple vulnerabilities.Description
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 Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Apache version 2.4.12 or later. Alternatively, ensure that the affected modules are not in use.See Also
