AI risk analysis

Summary: The flaw allows an unauthenticated attacker to bypass authentication and potentially extract database data via SQL injection, posing a critical security risk.
Exploitability: Exploitation is relatively easy as it requires submitting a specific payload to the /userlogin endpoint, making it a significant threat.
Blast radius: If exploited, the attacker could gain full access to the database, leading to data breaches and potential system compromise.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Disable the affected /userlogin endpoint or apply a patch to sanitize user input and prevent SQL injection, such as upgrading to the latest version of the software.

NVD description

Miantang/IoT-PHP's index.php implements a POST /userlogin route that reads the password directly from ['pwd'] with no sanitization and concatenates it into a raw SQL string: mysql_query("select * from userlists where username='' and password='' limit 1"). An unauthenticated attacker can submit a payload such as pwd=' OR '1'='1 to bypass authentication and, via UNION-based injection, extract arbitrary data from the database.
