CVE-2023-41594

Vulnerability

The Dairy Farm Shop Management System Using PHP and MySQL v1.1 contains multiple SQL injection vulnerabilities in the Login function. The application fails to sanitize user-supplied input passed through the Username and Password parameters, allowing an attacker to inject arbitrary SQL commands [1][2]. This affects version 1.1 as disclosed in the official description and the referenced GitHub advisory [3].

Exploitation

An attacker can exploit these vulnerabilities without requiring prior authentication. By submitting specially crafted strings (e.g., SQL meta-characters such as a single quote) in the username or password fields of the login form, the attacker can break out of the intended SQL query structure [1]. The injected payload is then executed by the database server against the application's backend MySQL database [2][3].

Impact

Successful exploitation enables the attacker to read, modify, or delete arbitrary data stored in the database, potentially gaining unauthorized access to other users' credentials or sensitive farm management records [1][2]. In some configurations, the attacker might be able to escalate the attack to compromise the underlying server or perform denial-of-service actions [1][3].

Mitigation

As of the publication date (2023-09-08), no official patch has been released for version 1.1. The vendor should implement parameterized queries (prepared statements) to ensure user input is treated as data rather than executable SQL code [2]. Until a fix is available, administrators are advised to restrict network access to the login page and monitor database logs for suspicious queries.
