CVE-2026-2057 Overview
A SQL Injection vulnerability has been identified in SourceCodester Medical Center Portal Management System version 1.0. This vulnerability affects the /login.php file where the User argument is susceptible to SQL injection attacks. The flaw allows remote attackers to manipulate SQL queries through crafted input, potentially compromising the underlying database and sensitive medical records stored within the system.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive patient data, modify database records, or potentially gain unauthorized access to the medical center portal system.
Affected Products
- Bontrofftech Medical Center Portal Management System version 1.0
- SourceCodester Medical Center Portal Management System 1.0

Technical Details for CVE-2026-2057
Vulnerability Analysis
This SQL Injection vulnerability (CWE-89) exists in the login functionality of the Medical Center Portal Management System. The application fails to properly sanitize user-supplied input in the User parameter before incorporating it into SQL queries. This allows attackers to inject malicious SQL statements that are executed by the backend database server.
The vulnerability is classified under both CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) and CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), indicating a fundamental input validation failure in the authentication mechanism.
Healthcare applications are particularly sensitive targets due to the protected health information (PHI) they contain, making this vulnerability especially concerning for medical facilities using this portal system.
Root Cause
The root cause of this vulnerability is improper input validation and lack of parameterized queries in the /login.php file. The application directly concatenates user input from the User parameter into SQL queries without proper sanitization or the use of prepared statements. This classic SQL injection pattern allows attackers to break out of the intended query structure and execute arbitrary SQL commands.
Attack Vector
The attack can be executed remotely over the network without requiring authentication. An attacker can craft malicious input containing SQL metacharacters and inject them through the User parameter in the login form. The exploit is publicly known, increasing the risk of widespread exploitation.
The attack flow typically involves:
- Identifying the vulnerable /login.php endpoint
- Crafting SQL injection payloads targeting the User parameter
- Submitting malicious requests to bypass authentication or extract data
- Exploiting database access to retrieve sensitive medical records or escalate privileges
Technical details and proof-of-concept information can be found in the GitHub CVE Issue #1 and VulDB #344617.
Detection Methods for CVE-2026-2057
Indicators of Compromise
- Unusual SQL error messages in web server logs originating from /login.php
- Multiple failed login attempts with suspicious characters (single quotes, semicolons, UNION statements) in the username field
- Database query logs showing unexpected queries or data extraction attempts
- Anomalous database access patterns from the web application user account
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in POST requests to /login.php
- Enable detailed logging on the database server to capture suspicious queries
- Implement intrusion detection signatures for common SQL injection attack patterns
- Monitor for authentication bypass indicators such as successful logins without valid credentials
Monitoring Recommendations
- Review web server access logs for requests to /login.php containing SQL injection indicators
- Configure alerts for database errors related to malformed SQL syntax
- Monitor database user privilege changes and unexpected data access
- Implement real-time alerting for multiple failed authentication attempts followed by a successful login
How to Mitigate CVE-2026-2057
Immediate Actions Required
- Restrict network access to the Medical Center Portal Management System to trusted IP addresses only
- Implement a Web Application Firewall with SQL injection protection rules
- Consider taking the application offline until a patch is available or input validation is implemented
- Review database logs for signs of prior exploitation
Patch Information
No official vendor patch has been released at this time. The vulnerability affects SourceCodester Medical Center Portal Management System version 1.0 distributed by Bontrofftech. Organizations should monitor SourceCodester for security updates and patch announcements. For additional vulnerability tracking information, refer to VulDB CTI #344617.
Workarounds
- Implement input validation on the /login.php file to sanitize the User parameter
- Use prepared statements with parameterized queries for all database interactions
- Deploy a reverse proxy or WAF to filter malicious SQL injection attempts
- Implement rate limiting on the login endpoint to slow down automated attacks
# Example Apache mod_security rule to block common SQL injection
SecRule ARGS:User "@rx (?i)(union.*select|select.*from|insert.*into|delete.*from|drop.*table)" \
"id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt Detected'"
