The Campcodes Online Apartment Visitor Management System 1.0 contains a critical SQL injection vulnerability that permits remote, unauthenticated attackers to execute arbitrary database commands.

This vulnerability is a SQL injection (CWE-89) flaw located in the index.php file, where the Username parameter fails to properly sanitize user input. The vulnerability is exploitable remotely by unauthenticated attackers.

Successful exploitation of this SQL injection vulnerability could allow an attacker to bypass authentication, access sensitive visitor data, or modify database contents. Given the CVSS score of 7.3, this represents a significant risk to the confidentiality and integrity of the application, potentially leading to unauthorized data exfiltration or system compromise.

Immediate Action: As no official patch is currently available, administrators should restrict network access to the affected system or implement rigorous input validation rules for the Username parameter. If possible, consider isolating the application until a security update is released by the vendor.

Proactive Monitoring: Security teams should monitor web server logs for suspicious patterns in the Username field, such as SQL syntax characters or unexpected query structures. Review database logs for anomalous queries originating from the web application service account.

Compensating Controls: Deploy a Web Application Firewall (WAF) with specific rules configured to detect and block SQL injection payloads targeting the index.php endpoint.

Public Exploit Available: Yes, a published proof-of-concept exists as documented in the research write-up at https://github.com/arpcyber040/CVE/issues/3.

Due to the availability of a public proof-of-concept and the ease of remote exploitation, this vulnerability poses a clear and present risk to any organization running version 1.0 of the Campcodes Online Apartment Visitor Management System. Organizations should prioritize implementing WAF filtering or network isolation immediately while awaiting a vendor-supplied patch.
