CVE-2025-7599 is a SQL Injection vulnerability identified in version 1.3 of the PHPGurukul Dairy Farm Shop Management System, specifically within the /invoice.php file. The vulnerability arises from improper sanitization of the 'del' parameter, which an attacker can manipulate to inject malicious SQL code. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The CVSS 4.0 base score is 5.3, indicating a medium severity level. The vector details show that the attack can be performed remotely (AV:N), requires low attack complexity (AC:L), no privileges (PR:L) but some level of privilege is needed (PR:L), no user interaction (UI:N), and results in low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vulnerability does not affect system confidentiality, integrity, or availability to a critical extent but still poses a significant risk due to the potential for unauthorized data access or manipulation. Since the vulnerability affects a niche software product used in managing dairy farm shops, the impact is more localized to organizations using this system for invoicing and shop management. The lack of patches at the time of disclosure necessitates immediate attention to mitigate risks.

For European organizations using the PHPGurukul Dairy Farm Shop Management System 1.3, this vulnerability could lead to unauthorized access to sensitive business data, including invoices and transaction records. Attackers exploiting this SQL Injection flaw could manipulate or extract data, potentially leading to financial fraud, data breaches, or disruption of business operations. Given the nature of the software, primarily used in retail and inventory management within dairy farm shops, the impact may be more pronounced in small to medium enterprises in the agricultural sector. Additionally, compromised data integrity could affect supply chain trust and regulatory compliance, especially under GDPR mandates concerning data protection. While the vulnerability does not directly threaten system availability, the possibility of data manipulation or leakage could have reputational and operational consequences for affected businesses.

1. Immediate mitigation should include disabling or restricting access to the vulnerable /invoice.php endpoint until a patch is available. 2. Implement Web Application Firewall (WAF) rules to detect and block SQL Injection patterns targeting the 'del' parameter. 3. Conduct input validation and sanitization on all user-supplied inputs, especially the 'del' parameter, using parameterized queries or prepared statements to prevent injection. 4. Monitor logs for unusual database queries or repeated access attempts to the vulnerable endpoint. 5. Engage with the vendor or community to obtain or develop patches or updates that address this vulnerability. 6. For organizations unable to patch immediately, consider isolating the affected system from external networks or restricting access to trusted IPs. 7. Educate staff on recognizing signs of compromise and establish incident response procedures specific to web application attacks.
