CVE-2025-4881 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Restaurant Management System, specifically within the /admin/user_save.php file. The vulnerability arises due to improper sanitization or validation of user-supplied input in the username or name parameter, allowing an attacker to inject malicious SQL code. This flaw can be exploited remotely without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:N/UI:N). Successful exploitation could lead to unauthorized access to the backend database, potentially allowing attackers to read, modify, or delete sensitive data related to restaurant management operations, including user credentials, menus, orders, or financial records. The CVSS score of 6.9 (medium severity) reflects the moderate impact on confidentiality, integrity, and availability, with low attack complexity and no privileges or user interaction needed. Although no public exploits are currently known in the wild, the vulnerability has been disclosed publicly, increasing the risk of exploitation by threat actors. The lack of available patches or mitigations from the vendor further elevates the urgency for affected organizations to implement protective measures.

For European organizations using the itsourcecode Restaurant Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their operational data. Compromise could lead to exposure of sensitive customer information, disruption of restaurant operations, and potential financial losses. Given the remote and unauthenticated nature of the exploit, attackers could automate attacks at scale, impacting multiple establishments. This could also damage brand reputation and lead to regulatory consequences under GDPR if personal data is compromised. The impact extends beyond individual restaurants to supply chain partners and service providers integrated with the system, potentially amplifying the damage within the European hospitality sector.

Since no official patches are currently available, European organizations should immediately implement the following mitigations: 1) Restrict network access to the /admin/user_save.php endpoint using firewalls or web application firewalls (WAFs) to allow only trusted IP addresses or VPN connections. 2) Employ WAF rules specifically designed to detect and block SQL injection patterns targeting the username/name parameters. 3) Conduct thorough input validation and sanitization at the application layer if source code access and modification are possible, focusing on parameterized queries or prepared statements to prevent injection. 4) Monitor logs for unusual database query patterns or repeated failed attempts to identify potential exploitation attempts. 5) Isolate the affected system within the network to limit lateral movement in case of compromise. 6) Plan for an urgent update or migration to a patched version once available from the vendor. 7) Educate administrative users on the risks and signs of compromise to enable rapid incident response.
