CVE-2020-9425: rConfig

High severity, CVSS 7.5. EPSS: 19% chance of exploitation in the next 30 days.

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.
