Summary
FreeSMS 2.1.2 contains a boolean-based blind SQL injection vulnerability in the password parameter that allows unauthenticated attackers to bypass authentication by injecting SQL code through the login endpoint. Attackers can exploit the vulnerable password parameter in requests to /pages/crc_handler.php?method=login to authenticate as any known user and subsequently modify their password via the profile update function.
