The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3958 advisory.

  - In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline     character in a malicious filename, rather than matching only the end of the filename. This could be     exploited in environments where uploads of some files are are externally blocked, but only by matching the     trailing portion of the filename. (CVE-2017-15715)

  - In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI     applications (SessionEnv on, not the default), a remote user may influence their content by using a     Session header. This comes from the HTTP_SESSION variable name used by mod_session to forward its data     to CGIs, since the prefix HTTP_ is also used by the Apache HTTP Server to pass HTTP header fields, per     CGI specifications. (CVE-2018-1283)

  - A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30     due to an out of bound read while preparing data to be cached in shared memory. It could be used as a     Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk     since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.
    (CVE-2018-1303)

  - In Apache HTTP server 2.4.0 to 2.4.39, 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-2019-10098)

  - 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 an unexpected URL within     the request URL. (CVE-2020-1927)

  - 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)

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