CVE-2025-3183: Online Doctor Appointment System SQLi Flaw

CVE-2025-3183 Overview

A SQL injection vulnerability has been identified in Projectworlds Online Doctor Appointment Booking System version 1.0. This vulnerability exists in the patient profile update functionality, specifically within the /patient/patientupdateprofile.php file. The manipulation of the patientFirstName argument allows attackers to inject malicious SQL commands that can be executed against the underlying database. According to the CVE description, other parameters in this file may also be affected by similar injection flaws.

Critical Impact

Unauthenticated remote attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive patient medical records and appointment data stored in the healthcare system's database.

Affected Products

• Projectworlds Online Doctor Appointment Booking System PHP and MySQL version 1.0

Technical Details for CVE-2025-3183

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) stems from improper neutralization of special elements used in SQL commands within the patient profile update functionality. The affected endpoint /patient/patientupdateprofile.php fails to properly validate and sanitize user-supplied input before incorporating it into SQL queries. This allows attackers to craft malicious input through the patientFirstName parameter that alters the intended SQL query logic.

The vulnerability is classified under both CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating a fundamental failure in input validation and output encoding practices. The attack can be initiated remotely without requiring authentication, and the exploit details have been publicly disclosed, increasing the risk of active exploitation.

Root Cause

The root cause of this vulnerability is the direct incorporation of user-supplied input into SQL queries without proper parameterization or input sanitization. The patientFirstName parameter value is likely concatenated directly into a SQL statement rather than being passed through prepared statements or parameterized queries. This coding pattern is particularly dangerous in healthcare applications where sensitive patient information is processed and stored.

Attack Vector

The vulnerability is exploitable over the network without any authentication requirements or user interaction. An attacker can submit a specially crafted HTTP request to the /patient/patientupdateprofile.php endpoint containing SQL metacharacters within the patientFirstName parameter. When the application processes this request, the injected SQL commands are executed against the database with the same privileges as the application's database connection.

Successful exploitation could allow attackers to extract sensitive patient information including medical records and personal data, modify or delete existing database records, bypass authentication mechanisms, and potentially gain further access to the underlying server depending on the database configuration. The public disclosure of this vulnerability and its exploit details significantly increases the risk of widespread exploitation.

Detection Methods for CVE-2025-3183

Indicators of Compromise

• Unusual SQL error messages appearing in application logs or error responses from the /patient/patientupdateprofile.php endpoint
• HTTP requests to /patient/patientupdateprofile.php containing SQL keywords or special characters (e.g., ', --, UNION, SELECT, DROP) in the patientFirstName parameter
• Unexpected database queries or query execution times associated with the patient profile update functionality
• Evidence of data exfiltration or unauthorized access to patient records

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the patientupdateprofile.php endpoint
• Configure database activity monitoring to alert on unusual query patterns, especially those containing multiple statement execution or data extraction commands
• Enable detailed application logging for all requests to /patient/patientupdateprofile.php and analyze for malicious input patterns
• Deploy network intrusion detection signatures to identify SQL injection attack payloads in HTTP traffic

Monitoring Recommendations

• Monitor HTTP request logs for the affected endpoint /patient/patientupdateprofile.php for signs of injection attempts
• Set up alerts for database errors or anomalous query execution patterns that may indicate exploitation attempts
• Implement real-time monitoring of database access patterns, particularly focusing on bulk data access or unauthorized schema queries
• Review authentication logs for suspicious access patterns to patient profile update functionality

How to Mitigate CVE-2025-3183

Immediate Actions Required

• If possible, restrict network access to the /patient/patientupdateprofile.php endpoint to trusted IP addresses only
• Implement Web Application Firewall rules to filter SQL injection patterns in requests to the affected endpoint
• Review and audit all patient profile update functionality for additional injection points
• Consider temporarily disabling the patient profile update feature if it is not business-critical until a proper fix is implemented

Patch Information

As of the last NVD update on 2025-04-15, no official vendor patch has been released for this vulnerability. Organizations using Projectworlds Online Doctor Appointment Booking System should monitor the VulDB entry and the GitHub CVE Issue Discussion for updates on available patches or vendor advisories.

Workarounds

• Implement input validation and sanitization for the patientFirstName parameter and all other user inputs in the affected file
• Modify the application code to use prepared statements or parameterized queries instead of string concatenation for SQL query construction
• Deploy a Web Application Firewall configured with SQL injection prevention rules in front of the application
• Restrict database user privileges used by the application to the minimum necessary permissions to limit the impact of successful exploitation
