"The version of Apache httpd installed on the remote host is prior to 2.4.42. It is, therefore, affected by multiple
vulnerabilities as referenced in the 2.4.42 advisory.

  - In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may
    use uninitialized memory when proxying to a malicious
    FTP server. (CVE-2020-1934)

  - In Apache HTTP Server 2.4.0 to 2.4.41, redirects
    configured with mod_rewrite that were intended to be
    self-referential might be fooled by encoded newlines and
    redirect instead to an unexpected URL within the
    request URL. (CVE-2020-1927)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
