CVE-2025-5602 Overview
A critical SQL injection vulnerability has been identified in Campcodes Hospital Management System 1.0. The flaw exists within the /admin/registration.php file, where the full_name parameter fails to properly sanitize user input before being used in SQL queries. This allows remote attackers to inject malicious SQL statements and potentially compromise the underlying database, extract sensitive patient data, or modify healthcare records.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive healthcare data including patient records, medical histories, and administrative credentials without authentication.

Technical Details for CVE-2025-5602
Vulnerability Analysis
This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the administrative registration functionality of the Campcodes Hospital Management System. The vulnerable endpoint at /admin/registration.php accepts user-supplied input through the full_name parameter without implementing proper input validation or parameterized queries.
When processing registration requests, the application directly concatenates user input into SQL query strings, allowing attackers to break out of the intended query context and execute arbitrary SQL commands. This is particularly dangerous in a healthcare context where databases typically contain protected health information (PHI), patient demographics, and administrative credentials.
The network-accessible nature of this vulnerability means attackers can exploit it remotely without requiring any authentication or user interaction, significantly lowering the barrier to successful exploitation.
Root Cause
The root cause of CVE-2025-5602 is the absence of input sanitization and the use of dynamic SQL query construction in the registration.php file. Instead of using prepared statements or parameterized queries, the application directly embeds the full_name parameter value into SQL statements. This classic injection pattern allows special SQL characters and commands to be interpreted as part of the query structure rather than as literal data values.
Attack Vector
The attack is executed remotely over the network by sending crafted HTTP requests to the /admin/registration.php endpoint. An attacker manipulates the full_name parameter to include SQL metacharacters and malicious query fragments. Since the exploit has been publicly disclosed, attackers can leverage this information to craft payloads that:
- Extract database contents using UNION-based or error-based injection techniques
- Bypass authentication by manipulating query logic
- Modify or delete critical healthcare records
- Potentially achieve command execution if database configurations permit
Technical details and proof-of-concept information are available in the GitHub SQL Injection Report.
Detection Methods for CVE-2025-5602
Indicators of Compromise
- Unusual SQL syntax patterns in web server access logs for /admin/registration.php
- Multiple failed or anomalous requests to the registration endpoint with special characters in the full_name parameter
- Database error messages appearing in application responses or logs
- Unexpected database queries containing UNION, SELECT, or other SQL keywords in parameter values
- Evidence of data exfiltration or unauthorized database access in audit logs
Detection Strategies
- Deploy web application firewall (WAF) rules to detect and block SQL injection patterns targeting the full_name parameter
- Implement application-layer logging that captures all parameters submitted to /admin/registration.php
- Configure database activity monitoring to alert on unusual query patterns or unauthorized data access
- Use intrusion detection systems (IDS) with signatures for common SQL injection payloads
Monitoring Recommendations
- Enable verbose logging on the Hospital Management System web server to capture request parameters
- Monitor database query logs for injection patterns such as quote characters, UNION statements, and comment sequences
- Set up alerts for multiple rapid requests to the registration endpoint from single IP addresses
- Review access logs for requests containing encoded characters or unusual payload lengths in form fields
How to Mitigate CVE-2025-5602
Immediate Actions Required
- Restrict network access to the /admin/registration.php endpoint using firewall rules or access control lists
- Implement a web application firewall (WAF) with SQL injection protection rules
- If possible, disable or remove the vulnerable registration functionality until a patch is available
- Review database accounts used by the application and enforce least-privilege principles
- Audit database logs for signs of exploitation and assess potential data exposure
Patch Information
No official vendor patch has been released for CVE-2025-5602 at this time. Organizations using Campcodes Hospital Management System 1.0 should monitor the CampCodes website for security updates. Additional vulnerability intelligence is available through VulDB.
Workarounds
- Implement input validation on the full_name parameter to reject SQL metacharacters and special characters
- Modify the application code to use parameterized queries or prepared statements for all database interactions
- Deploy a reverse proxy or WAF configured to sanitize incoming requests to vulnerable endpoints
- Restrict access to administrative functions to trusted IP addresses only
- Consider implementing additional authentication layers for the admin registration functionality
# Example: Block access to vulnerable endpoint using iptables (adjust as needed)
# Restrict access to admin registration to internal network only
iptables -A INPUT -p tcp --dport 80 -m string --string "/admin/registration.php" --algo bm -j DROP
# Example: Apache .htaccess rule to restrict access
# Add to .htaccess in web root
<Files "registration.php">
Require ip 192.168.1.0/24
Require ip 10.0.0.0/8
