CVE-2025-4869 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Restaurant Management System, specifically within the /admin/member_update.php file. The vulnerability arises from improper sanitization or validation of the 'menu' parameter, which can be manipulated by an unauthenticated remote attacker to inject malicious SQL commands. This flaw allows attackers to execute arbitrary SQL queries on the backend database, potentially leading to unauthorized data access, data modification, or deletion. The vulnerability does not require any authentication or user interaction, making it remotely exploitable over the network. Although the CVSS 4.0 base score is 6.9, categorized as medium severity, the impact on confidentiality, integrity, and availability is low to limited, as indicated by the CVSS vector metrics (VC:L, VI:L, VA:L). No known exploits have been reported in the wild yet, and no official patches or mitigations have been published by the vendor. The vulnerability was publicly disclosed shortly after being reserved, indicating a rapid disclosure timeline. Given the nature of restaurant management systems, which typically handle sensitive customer data, order information, and possibly payment details, exploitation could lead to data breaches or operational disruptions.

For European organizations using the itsourcecode Restaurant Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive business and customer data stored in the backend database. Attackers could manipulate or exfiltrate data related to customer orders, employee information, or financial transactions, potentially leading to privacy violations under GDPR. Operationally, successful exploitation could disrupt restaurant management workflows, impacting service availability and causing reputational damage. Although the vulnerability's impact on confidentiality, integrity, and availability is rated low to limited, the ease of remote exploitation without authentication increases risk exposure. European restaurants and hospitality businesses relying on this system could face compliance issues and financial losses if exploited. The absence of known exploits in the wild currently reduces immediate threat levels, but public disclosure increases the likelihood of future exploitation attempts.

Organizations should immediately audit their deployment of the itsourcecode Restaurant Management System version 1.0 to determine exposure. Since no official patch is currently available, mitigation should focus on implementing web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the 'menu' parameter in /admin/member_update.php. Input validation and sanitization should be enforced at the application level, ideally by applying parameterized queries or prepared statements if source code access is available. Restricting access to the /admin directory via IP whitelisting or VPN can reduce exposure. Monitoring database logs for unusual queries and setting up intrusion detection systems to alert on suspicious activity is recommended. Organizations should also prepare incident response plans in case of exploitation and stay alert for vendor patches or updates. If feasible, upgrading to a newer, patched version of the software or migrating to alternative solutions should be considered.
