Mitigation checklist
- Disable the mod_proxy_ftp module or ensure forward proxying is disabled in the Apache HTTP Server configuration. 1. Comment out the mod_proxy_ftp module load line in `/etc/httpd/conf.modules.d/00-proxy.conf`: ``` # LoadModule proxy_ftp_module modules/mod_proxy_ftp.so ``` 2. Ensure forward proxying is turned off in `/etc/httpd/conf/httpd.conf`: ``` ProxyRequests Off ``` 3. Reload the httpd service to apply changes: ``` systemctl reload httpd ``` Caveat: Disabling mod_proxy_ftp terminates the ability of httpd to proxy FTP requests. Warning: Reloading or restarting the httpd service will briefly affect active connections while configuration changes are reloaded.
