CVE-2025-4870 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Restaurant Management System, specifically within the /admin/menu_save.php file. The vulnerability arises from improper sanitization or validation of the 'menu' parameter, which can be manipulated by an attacker to inject malicious SQL commands. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL queries against the backend database without requiring any user interaction or privileges. The vulnerability is classified with a CVSS 4.0 base score of 6.9, indicating a medium severity level. The vector details (AV:N/AC:L/AT:N/PR:N/UI:N) confirm that the attack can be performed remotely over the network with low attack complexity, no privileges, and no user interaction required. The impact metrics (VC:L/VI:L/VA:L) suggest limited confidentiality, integrity, and availability impacts, likely due to partial access or limited database exposure. No patches or exploit code have been publicly disclosed yet, and no known active exploitation in the wild has been reported. However, the public disclosure of the vulnerability details increases the risk of exploitation attempts. SQL Injection vulnerabilities are critical because they can lead to unauthorized data access, data modification, or even full system compromise depending on the database permissions and application architecture. Given the affected component is an administrative menu save function, exploitation could allow attackers to manipulate menu data or extract sensitive information from the database, potentially disrupting restaurant operations or exposing customer and business data.

For European organizations using the itsourcecode Restaurant Management System version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their operational data. Restaurants and hospitality businesses rely heavily on management systems to handle orders, menus, customer data, and billing. Exploitation could lead to unauthorized disclosure of sensitive customer information, manipulation of menu items or pricing, and disruption of service availability. Such impacts could damage customer trust, lead to regulatory non-compliance (e.g., GDPR violations if personal data is exposed), and cause financial losses. Additionally, compromised systems could be leveraged as pivot points for further attacks within the organization's network. The medium severity rating suggests that while the vulnerability is exploitable remotely without authentication, the extent of damage may be limited by the application's database permissions or architecture. Nonetheless, the risk is non-negligible, especially for organizations lacking robust network segmentation or monitoring. The absence of known active exploitation does not eliminate the threat, as attackers often develop exploits rapidly after public disclosure.

European organizations should immediately assess their exposure to the itsourcecode Restaurant Management System version 1.0. Since no official patch is currently available, the following specific mitigations are recommended: 1) Implement Web Application Firewall (WAF) rules tailored to detect and block SQL injection patterns targeting the 'menu' parameter in /admin/menu_save.php. 2) Restrict network access to the administrative interface to trusted IP addresses or VPN-only access to reduce the attack surface. 3) Conduct thorough input validation and sanitization on all user-supplied data, especially the 'menu' parameter, employing parameterized queries or prepared statements if possible. 4) Monitor database logs and application logs for unusual query patterns or errors indicative of injection attempts. 5) Consider deploying database user accounts with the least privileges necessary for the application to limit the impact of potential exploitation. 6) Plan for an immediate upgrade or patch deployment once the vendor releases a fix. 7) Educate IT and security teams about this vulnerability to ensure rapid detection and response to any suspicious activity. These targeted measures go beyond generic advice by focusing on the specific vulnerable component and attack vector.
