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.
