CVE-2025-11348 identifies a SQL injection vulnerability in Campcodes Online Apartment Visitor Management System version 1.0, specifically in the handling of the Username parameter within the /index.php file. This vulnerability allows an unauthenticated remote attacker to inject malicious SQL commands by manipulating the Username argument, potentially leading to unauthorized access, data leakage, or data manipulation within the backend database. The vulnerability does not require any user interaction or privileges, making it straightforward to exploit over the network. The CVSS v4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low attack complexity and no authentication required, but with limited impact on confidentiality, integrity, and availability (all rated low). Although no known exploits are currently active in the wild, the public disclosure of the vulnerability increases the likelihood of exploitation attempts. The absence of official patches or mitigation guidance from the vendor at this time necessitates immediate defensive measures by users of this system. The vulnerability primarily affects version 1.0 of the product, which is used in managing visitor access in apartment complexes, making it a critical component in physical security and tenant data protection. Exploitation could allow attackers to bypass visitor management controls, access sensitive tenant information, or disrupt system operations.

For European organizations, particularly property management companies and residential complexes using Campcodes Online Apartment Visitor Management System 1.0, this vulnerability poses a significant risk to both operational security and tenant privacy. Successful exploitation could lead to unauthorized disclosure of personally identifiable information (PII) of residents and visitors, violating GDPR and other data protection regulations. Integrity of visitor logs and access records could be compromised, undermining trust and potentially enabling physical security breaches. Availability impacts, while rated low, could still disrupt visitor management operations, causing inconvenience and reputational damage. The risk is heightened in countries with large urban populations and extensive apartment complexes relying on digital visitor management solutions. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within organizational IT infrastructure. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional factors. However, the ease of remote exploitation without authentication increases urgency for mitigation.

To mitigate CVE-2025-11348, European organizations should immediately implement the following measures: 1) Apply input validation and sanitization on the Username parameter to prevent injection of malicious SQL code. 2) Refactor the application code to use parameterized queries or prepared statements, eliminating direct concatenation of user input into SQL commands. 3) Deploy web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the /index.php endpoint. 4) Restrict network access to the visitor management system to trusted internal networks or VPNs, minimizing exposure to external attackers. 5) Monitor logs for unusual database query patterns or repeated failed login attempts that may indicate exploitation attempts. 6) Engage with the vendor for patches or updates and plan for timely deployment once available. 7) Conduct security assessments and penetration testing focused on injection vulnerabilities within the visitor management system. 8) Educate IT and security teams about this specific vulnerability to ensure rapid detection and response. These targeted actions go beyond generic advice by focusing on the specific attack vector and system context.
