Mitigation checklist
- Disable the mod_charset_lite module if character set translation is not required. 1. Locate the configuration file loading the module, typically within `/etc/httpd/conf.modules.d/` (such as `00-base.conf` or a dedicated module configuration file). 2. Comment out or remove the `LoadModule charset_lite_module` line: ``` # LoadModule charset_lite_module modules/mod_charset_lite.so ``` 3. Reload the httpd service to apply the configuration change: ``` systemctl reload httpd ``` Caveats: Applications that depend on mod_charset_lite for on-the-fly character set conversion will fail to translate character sets once the module is disabled. Warning: Reloading or restarting the httpd service will momentarily disrupt active network connections or in-flight requests.
