CVE-2025-9833 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Online Farm Management System, specifically within the /Login/login.php file. The vulnerability arises from improper sanitization or validation of the 'uname' parameter, which is used during the login process. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. The vulnerability does not require authentication or user interaction, and the attack vector is network accessible (remote). The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of exploitation (low attack complexity, no privileges or user interaction needed) but limited impact on confidentiality, integrity, and availability (low to limited impact). The vulnerability could enable attackers to bypass authentication, extract sensitive data, or modify database contents, depending on the database privileges of the affected application. Although no known exploits are currently observed in the wild, the exploit code is publicly available, increasing the risk of exploitation. No official patches or mitigation links have been published yet, indicating that affected users must rely on other defensive measures until a fix is released.

For European organizations using the SourceCodester Online Farm Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of farm management data, which may include sensitive operational, financial, and personal information. Unauthorized access could lead to data breaches, manipulation of farm records, disruption of farm operations, and potential financial losses. Given the critical role of farm management systems in agricultural supply chains, exploitation could also indirectly affect food production and distribution. The remote and unauthenticated nature of the vulnerability increases the likelihood of exploitation, especially in environments where the system is exposed to the internet without adequate network protections. Organizations in Europe with digitalized agricultural operations or those relying on this specific software version are at risk of targeted or opportunistic attacks. The medium severity rating suggests that while the impact is not catastrophic, it is substantial enough to warrant immediate attention to prevent escalation or lateral movement within networks.

1. Immediate mitigation should include restricting external access to the Online Farm Management System login interface through network segmentation, firewalls, or VPNs to limit exposure to untrusted networks. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'uname' parameter. 3. Conduct manual code review and apply input validation and parameterized queries or prepared statements in the login.php file to sanitize user inputs and prevent SQL injection. 4. Monitor logs for unusual login attempts or SQL errors that may indicate exploitation attempts. 5. If possible, temporarily disable or replace the vulnerable login functionality with a more secure authentication mechanism until an official patch is released. 6. Engage with the vendor or SourceCodester community to obtain or request a security patch and apply it promptly once available. 7. Educate IT and security teams about this vulnerability to raise awareness and ensure rapid incident response if exploitation is detected.
