CVE-2025-4884 is a critical SQL Injection vulnerability identified in version 1.0 of the itsourcecode Restaurant Management System. The flaw exists in the /admin/assign_save.php file, specifically through the manipulation of the 'team' parameter. This vulnerability allows an unauthenticated attacker to remotely inject malicious SQL code into the backend database queries executed by the application. Because the attack vector requires no authentication or user interaction, the vulnerability can be exploited remotely with relative ease. The injection could lead to unauthorized data disclosure, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the restaurant management system's data. The CVSS 4.0 base score is 6.9, categorized as medium severity, reflecting the lack of authentication and ease of exploitation but limited scope and impact on system components. Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The absence of patches or mitigation guidance from the vendor further elevates the threat. The vulnerability affects only version 1.0 of the software, which may limit exposure to organizations that have not upgraded or replaced this system. Given the nature of restaurant management systems, which often handle sensitive customer data, payment information, and operational details, exploitation could have significant operational and reputational consequences.

For European organizations using the itsourcecode Restaurant Management System version 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive customer data, including personal and payment information, violating GDPR and other data protection regulations, potentially resulting in heavy fines and legal consequences. Operational disruption could occur if attackers modify or delete critical data, impacting order processing, inventory management, and staff assignments. This could lead to financial losses and damage to customer trust. Additionally, attackers could leverage the vulnerability as a foothold to pivot into broader network environments, especially if the restaurant management system is integrated with other internal systems. The medium CVSS score suggests moderate impact, but the lack of authentication and remote exploitability increases the urgency for European organizations to address this vulnerability promptly. The public disclosure without available patches means organizations must rely on alternative mitigations to protect their environments.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, restrict network access to the /admin/assign_save.php endpoint by applying firewall rules or web application firewall (WAF) policies to limit access only to trusted IP addresses or internal networks. Second, deploy WAF rules specifically designed to detect and block SQL injection patterns targeting the 'team' parameter. Third, conduct thorough input validation and sanitization at the application or proxy level to neutralize malicious input. Fourth, monitor logs for unusual or suspicious activity related to the vulnerable endpoint to enable early detection of exploitation attempts. Fifth, consider isolating or segmenting the restaurant management system from critical internal networks to reduce lateral movement risk. Finally, engage with the vendor or community to obtain or develop patches or updated versions that address the vulnerability. Regular backups of the system and data should be maintained to enable recovery in case of compromise.
