CVE-2025-5603: Campcodes Hospital Management SQL Injection

CVE-2025-5603 Overview

A critical SQL injection vulnerability has been discovered in Campcodes Hospital Management System version 1.0. The vulnerability exists in the /registration.php file, where improper sanitization of the full_name and username parameters allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially compromising the entire hospital management database containing sensitive patient information.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete sensitive healthcare data including patient records, medical histories, and administrative credentials without requiring any authentication.

Affected Products

• Campcodes Online Hospital Management System 1.0
• Hospital Management System registration module (/registration.php)

Technical Details for CVE-2025-5603

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the user registration functionality of the Campcodes Hospital Management System. The /registration.php endpoint accepts user-supplied data through the full_name and username parameters, which are directly incorporated into SQL queries without proper sanitization or parameterization. This allows attackers to manipulate the query structure and execute arbitrary SQL commands against the backend database.

Healthcare management systems are particularly high-value targets due to the sensitive nature of patient data they contain, including personal health information (PHI), insurance details, and administrative credentials. Successful exploitation could lead to unauthorized data access, data manipulation, or complete database compromise.

Root Cause

The root cause of CVE-2025-5603 is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The application fails to properly sanitize or parameterize user input before incorporating it into SQL queries. The full_name and username parameters in the registration form are directly concatenated into database queries, allowing special SQL characters and commands to be interpreted as part of the query structure rather than as literal data values.

Attack Vector

The attack can be launched remotely over the network against any exposed instance of the Campcodes Hospital Management System. No authentication is required since the vulnerability exists in the registration page, which is publicly accessible by design. An attacker can craft malicious input containing SQL metacharacters and injection payloads within the full_name or username fields. When submitted, these payloads are executed by the database server, potentially allowing the attacker to:

• Extract sensitive data from the database using UNION-based or blind SQL injection techniques
• Bypass authentication mechanisms
• Modify or delete existing records
• Potentially escalate to remote code execution depending on database configuration

Technical details and proof-of-concept information are available through the GitHub PoC Repository and VulDB entry #311089.

Detection Methods for CVE-2025-5603

Indicators of Compromise

• Unusual database queries originating from the /registration.php endpoint containing SQL keywords such as UNION, SELECT, INSERT, DROP, or comment sequences (--, /*)
• Abnormal error messages in web server logs referencing SQL syntax errors or database exceptions
• Registration attempts with usernames or full_name values containing special characters like single quotes ('), semicolons (;), or SQL command sequences
• Unexpected database access patterns or bulk data extraction from patient tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in HTTP POST requests to /registration.php
• Implement database activity monitoring to identify suspicious query patterns, especially those accessing multiple tables or extracting large datasets
• Configure intrusion detection systems (IDS) with signatures for SQL injection attacks targeting registration forms
• Enable detailed logging on the web application to capture full request bodies for forensic analysis

Monitoring Recommendations

• Monitor web server access logs for repeated requests to /registration.php with varying payloads, indicative of automated injection testing
• Set up alerts for database query failures or exceptions originating from the registration functionality
• Track failed registration attempts that may indicate reconnaissance or exploitation attempts
• Implement real-time alerting on database queries that deviate from expected patterns for the registration module

How to Mitigate CVE-2025-5603

Immediate Actions Required

• Take the Campcodes Hospital Management System offline or restrict network access to trusted IP addresses until patches are applied
• Implement a Web Application Firewall (WAF) with SQL injection protection rules as an interim measure
• Review database logs for evidence of prior exploitation and conduct a security assessment of stored data
• Consider isolating the database server and rotating all database credentials

Patch Information

As of the last NVD update on 2025-06-10, no official vendor patch has been released for this vulnerability. Affected organizations should monitor the Campcodes website for security updates. Additional vulnerability information is available through VulDB CTI ID #311089.

Workarounds

• Implement prepared statements (parameterized queries) in the /registration.php file to properly separate SQL code from user data
• Apply strict input validation on the full_name and username fields, rejecting any input containing SQL metacharacters
• Deploy a reverse proxy or WAF with SQL injection filtering capabilities to sanitize incoming requests
• Restrict database user privileges for the application to minimum required permissions, preventing destructive operations
• Consider implementing stored procedures for registration operations to further isolate user input from direct SQL execution

# Example WAF configuration (ModSecurity)
# Add SQL injection protection rules for registration endpoint
SecRule REQUEST_URI "@contains /registration.php" \
    "id:1001,\
    phase:2,\
    deny,\
    status:403,\
    chain"
    SecRule ARGS "@rx (?i)(\b(union|select|insert|update|delete|drop|alter)\b)" \
        "t:lowercase,\
        msg:'SQL Injection attempt blocked on registration form'"
