Description

Section titled “Description”

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.
