CVE-2020-9425Public exploitNetwork attack vector

Credential disclosure via unterminated authentication redirect

Published Mar 20, 2020 · Updated Aug 4, 2024

Authentication bypass in rConfig before 3.9.4 allows remote attackers to read saved cleartext credentials through settings.php. The login check in includes/head.inc.php sends a redirect for unauthenticated sessions but fails to terminate execution, so settings.php still renders protected fields. No credentials or user interaction are required, and exposure is limited to credentials already saved in the application.
