"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.");
