CVE-2025-11599 identifies a SQL injection vulnerability in Campcodes Online Apartment Visitor Management System version 1.0. The vulnerability is located in the /forgot-password.php endpoint, specifically in the handling of the 'email' parameter. Due to insufficient input validation and sanitization, attackers can inject crafted SQL statements remotely without requiring authentication or user interaction. This injection can manipulate backend SQL queries, potentially allowing attackers to extract sensitive data, modify database contents, or disrupt service availability. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low complexity and no privileges or user interaction needed, but with limited impact on confidentiality, integrity, and availability. Although no known exploits in the wild have been reported, public exploit code availability increases the risk of opportunistic attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been linked yet. The lack of secure coding practices in input handling highlights the need for immediate remediation. This vulnerability is particularly critical for organizations managing sensitive visitor data and access control in residential environments.

For European organizations, especially those in property management and residential security sectors using Campcodes Online Apartment Visitor Management System 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of personal visitor information, undermining privacy regulations such as GDPR. Attackers might also alter or delete visitor records, causing operational disruptions or enabling unauthorized physical access. The integrity of authentication workflows, such as password resets, could be compromised, facilitating further account takeover attacks. Availability impacts could arise if attackers execute destructive SQL commands, potentially causing denial of service. Given the critical nature of visitor management in residential and commercial properties, exploitation could erode tenant trust and lead to regulatory penalties. The medium severity rating suggests a moderate but tangible threat that requires timely attention to avoid escalation or chained attacks.

Organizations should immediately audit their deployments of Campcodes Online Apartment Visitor Management System to identify affected versions. Until an official patch is released, implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the /forgot-password.php endpoint. Review and enforce strict input validation and sanitization on all user-supplied data, especially the 'email' parameter. Employ parameterized queries or prepared statements in the backend database interactions to eliminate injection vectors. Monitor database logs and application behavior for unusual queries or access patterns indicative of exploitation attempts. Educate IT and security teams about this vulnerability and ensure incident response plans include steps for SQL injection incidents. Once vendor patches become available, prioritize their deployment and verify successful remediation through penetration testing. Additionally, consider isolating the visitor management system network segment to limit lateral movement in case of compromise.
