An issue was discovered in includes/head.inc.php in rConfig before 3.9.4. An unauthenticated attacker can retrieve saved cleartext credentials via a GET request to settings.php. Because the application was not exiting after a redirect is applied, the rest of the page still executed, resulting in the disclosure of cleartext credentials in the response.

- →Send an unauthenticated HTTP GET request to /settings.php; a vulnerable rConfig instance will return HTTP 200 with cleartext credential fields in the response body instead of redirecting. ↗
- →Match response body for both 'defaultNodeUsername' and 'defaultNodePassword' strings simultaneously with HTTP status 200 to confirm exploitation.
- →Use Shodan query 'http.title:"rconfig"', FOFA query 'title="rconfig"', or Google dork 'intitle:"rconfig"' to identify exposed rConfig instances for scanning.
- ·Vulnerability only affects rConfig versions prior to 3.9.4; patched instances will properly redirect and not return credential data. ↗
- ·The root cause is a missing exit/die after redirect logic in includes/head.inc.php, causing the rest of the page (including credentials) to render in the HTTP response body even when a redirect header is set. ↗

rConfig <3.9.4 - Sensitive Information Disclosure
rConfig prior to version 3.9.4 is susceptible to sensitive information disclosure. An unauthenticated attacker can retrieve saved cleartext credentials via a GET request to settings.php. Because the application does not exit after a redirect is applied, the rest of the page still executes, resulting in the disclosure of cleartext credentials in the response.
