CRITICAL 10.0

DescriptionCVE.org

A SQL injection vulnerability exists in the Blood Bank Management System 1.0 within the receiverLogin.php component. The application fails to properly sanitize user-supplied input in SQL queries, allowing an attacker to inject arbitrary SQL code. By manipulating the remail and rpassword fields, an attacker can bypass authentication and gain unauthorized access to the system.

Analysis

Technical ContextAI

SQL injection occurs when user-supplied input is incorporated into SQL queries without proper sanitization or parameterized queries.

RemediationAI

Use parameterized queries or prepared statements. Apply input validation and escape special characters. Implement least-privilege database accounts.
