Synopsis

Apache 2.4.x < 2.4.39 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 the scanner 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.
