Question about CVE-2023-25690 Security vulnerability for MOI
Can you please verify and provide more information on this.
Where: Server_Virtual_Unix_Linux
Vulnerabilty: CVE-2023-25690
Description: 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 onRewriteRule \"^/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.
Release : 2.1
Regarding the concern about the security vulnerability CVE-2023-25690 as it relates to MOI.
MOI does not use Apache HTTP Server in the MOI deployment. If the security scan indicated such a vulnerability it is most likely that it is because of a presence of the Apache HTTP server on the host machine where MOI is installed, independent of MOI.
Here are the steps to check this on RHEL:
Is Apache 2 service running? Run the following systemctl command to determine:
systemctl status httpd
If it is running stop it and disable the startup at boot time:
systemctl disable httpd
systemctl stop httpd
You can verify if it is running after rebooting/startup:
systemctl status httpd
