- Mitigation guidance
- If uWSGI proxy functionality is not required, disable the mod_proxy_uwsgi module: 1. Edit the Apache proxy module configuration file (typically `/etc/httpd/conf.modules.d/00-proxy.conf`) and comment out the loading directive: # LoadModule proxy_uwsgi_module modules/mod_proxy_uwsgi.so 2. Restart the Apache HTTP Server daemon: systemctl restart httpd Warning: Restarting the httpd service causes an immediate disruption to active client connections. Disabling this module will prevent the server from handling requests routed through the uWSGI protocol.
