CVE-2025-11349 is a SQL injection vulnerability identified in Campcodes Online Apartment Visitor Management System version 1.0. The vulnerability resides in the /search-visitor.php script, specifically in the handling of the 'searchdata' parameter. This parameter is susceptible to SQL injection due to insufficient input validation or sanitization, allowing an attacker to craft malicious SQL payloads that are executed by the backend database. The attack vector is remote and does not require authentication or user interaction, making it highly accessible to threat actors. The vulnerability can lead to unauthorized data access, including visitor logs and potentially sensitive personal information, data modification, or even deletion, impacting data integrity and confidentiality. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the lack of authentication and user interaction requirements but limited scope and impact compared to more critical vulnerabilities. No patches or official fixes are currently listed, and while no active exploitation has been reported, a public exploit exists, increasing the likelihood of future attacks. The vulnerability affects only version 1.0 of the product, so organizations running this version should prioritize mitigation. The lack of scope change indicates the impact is confined to the vulnerable application and its database. This vulnerability highlights the importance of secure coding practices, especially input validation and use of parameterized queries to prevent injection attacks.

For European organizations, the exploitation of CVE-2025-11349 could result in unauthorized access to visitor management databases, leading to exposure of personally identifiable information (PII) of residents and visitors. This compromises confidentiality and could violate GDPR regulations, resulting in legal and financial penalties. Integrity of visitor records could be undermined, enabling attackers to manipulate logs, potentially facilitating unauthorized physical access or covering malicious activities. Availability impact is limited but could occur if attackers execute destructive SQL commands. The risk is particularly significant for property management firms and residential complexes relying on Campcodes systems for visitor tracking. The presence of a public exploit increases the risk of opportunistic attacks, including from cybercriminals targeting real estate or hospitality sectors. The medium severity suggests that while the vulnerability is serious, it may not lead to full system compromise without additional vulnerabilities or misconfigurations. However, the ease of exploitation and sensitive nature of the data involved necessitate prompt action to prevent data breaches and maintain trust with residents and regulatory bodies.

1. Immediately implement input validation and sanitization on the 'searchdata' parameter to reject or properly encode malicious inputs. 2. Refactor the vulnerable code to use parameterized queries or prepared statements to eliminate SQL injection risks. 3. If available, apply official patches or updates from Campcodes addressing this vulnerability; if not, contact the vendor for guidance. 4. Conduct a thorough security review of all user input handling in the application to identify and remediate similar injection flaws. 5. Monitor application logs for unusual query patterns or failed injection attempts to detect exploitation attempts early. 6. Restrict database user privileges to the minimum necessary to limit potential damage from SQL injection. 7. Consider deploying Web Application Firewalls (WAFs) with rules to detect and block SQL injection payloads targeting the application. 8. Educate development and IT teams on secure coding practices and the importance of regular security assessments. 9. For organizations unable to immediately patch, implement network segmentation and access controls to limit exposure of the vulnerable system. 10. Regularly back up visitor management data to enable recovery in case of data tampering or loss.
