The version of httpd installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-25690 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of httpd installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected
by a vulnerability as referenced in the CVE-2023-25690 advisory.
- Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request
Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of
RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied
request-target (URL) data and is then re-inserted into the proxied request-target using variable
substitution. For example, something like: RewriteEngine on RewriteRule ^/here/(.*)
http://example.com:8080/elsewhere?$1; [P] ProxyPassReverse /here/ http://example.com:8080/ Request
splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended
URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version
2.4.56 of Apache HTTP Server. (CVE-2023-25690)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
