Apache 2.4.x < 2.4.38 Multiple Vulnerabilities

Medium Nessus Plugin ID 121355


The remote web server is affected by multiple vulnerabilities.


According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.38. It is, therefore, affected by multiple vulnerabilities:

- A denial of service (DoS) vulnerability exists in HTTP/2 steam handling. An unauthenticated, remote attacker can exploit this issue, via sending request bodies in a slow loris way to plain resources, to occupy a server thread. (CVE-2018-17189)

- A vulnerability exists in mod_sesion_cookie, as it does not properly check the expiry time of cookies. (CVE-2018-17199)

- A denial of service (DoS) vulnerability exists in mod_ssl when used with OpenSSL 1.1.1 due to an interaction in changes to handling of renegotiation attempts. An unauthenticated, remote attacker can exploit this issue to cause mod_ssl to stop responding. (CVE-2019-0190)

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


Upgrade to Apache version 2.4.38 or later.
