Apache 2.4.x < 2.4.39 Multiple Vulnerabilities

high Nessus Plugin ID 123642

Language:

Synopsis

The remote web server is affected by multiple vulnerabilities.

Description

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.39. It is, therefore, affected by multiple vulnerabilities:

 - A privilege escalation vulnerability exists in module scripts due to an ability to execute arbitrary code as the parent process by manipulating the scoreboard. (CVE-2019-0211)

 - An access control bypass vulnerability exists in mod_auth_digest due to a race condition when running in a threaded server. An attacker with valid credentials could authenticate using another username. (CVE-2019-0217)

 - An access control bypass vulnerability exists in mod_ssl when using per-location client certificate verification with TLSv1.3. (CVE-2019-0215)

In addition, Apache httpd is also affected by several additional vulnerabilities including a denial of service, read-after-free and URL path normalization inconsistencies.

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 2.4.39 or later.
