AI risk analysis

Summary: The flaw allows an attacker to execute arbitrary SQL commands by exploiting improper input sanitization in the authentication query construction.
Exploitability: Exploitation is relatively straightforward given access to the cookie value, making it a high-risk vulnerability.
Blast radius: If exploited, this could lead to full database compromise and unauthorized access to user data.
Prioritized remediation: Implement proper input validation and sanitization for SQL queries, or use parameterized queries to prevent SQL injection.

NVD description

IOTSmartHome's gui/login.php checkCookie function builds an authentication query as SELECT * FROM users WHERE ID='<decoded lastLogin cookie>' after base64-decoding the client-supplied lastLogin cookie via safe_decode, which performs URL-safe base64 decoding with no sanitization of the decoded value before it is concatenated into the SQL string.
