CVE-2025-9305 Overview
A SQL injection vulnerability has been identified in SourceCodester Online Bank Management System version 1.0. The vulnerability exists in an unknown function within the file /bank/mnotice.php, where the manipulation of the ID parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, enabling unauthorized access to the underlying database.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to read, modify, or delete sensitive banking data, potentially compromising customer financial information and system integrity.

Technical Details for CVE-2025-9305
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) affects the /bank/mnotice.php endpoint in the Online Bank Management System. The root cause is improper neutralization of special elements used in SQL commands, classified under the broader injection vulnerability category (CWE-74). The vulnerability allows unauthenticated remote attackers to manipulate database queries through the ID parameter, potentially accessing or manipulating sensitive banking information stored in the backend database.
The exploit has been publicly disclosed, increasing the risk of active exploitation. Banking systems inherently contain sensitive customer data including account details, transaction histories, and personal information, making this vulnerability particularly concerning in financial application contexts.
Root Cause
The vulnerability stems from insufficient input validation and sanitization of the ID parameter in the /bank/mnotice.php file. User-supplied input is directly concatenated into SQL queries without proper parameterization or escaping, allowing attackers to inject arbitrary SQL syntax. This classic SQL injection pattern enables the manipulation of database queries to perform unauthorized operations.
Attack Vector
The attack can be initiated remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests to the /bank/mnotice.php endpoint with specially crafted ID parameter values containing SQL injection payloads. These payloads can be designed to extract sensitive data through UNION-based injection, manipulate data through INSERT/UPDATE/DELETE statements, or potentially achieve further system compromise depending on database permissions.
The vulnerability is accessible through standard web requests, making it trivial to exploit using common security testing tools or manual HTTP request manipulation. For technical details and proof-of-concept information, refer to the GitHub CVE Issue Discussion.
Detection Methods for CVE-2025-9305
Indicators of Compromise
- Unusual SQL error messages appearing in web application logs or responses
- Unexpected database queries or data access patterns involving the mnotice.php endpoint
- HTTP requests to /bank/mnotice.php containing SQL syntax characters such as single quotes, UNION keywords, or comment sequences in the ID parameter
- Database audit logs showing unauthorized SELECT, INSERT, UPDATE, or DELETE operations
Detection Strategies
- Implement web application firewall (WAF) rules to detect SQL injection patterns in the ID parameter of requests to /bank/mnotice.php
- Monitor HTTP access logs for suspicious requests targeting the vulnerable endpoint with unusual parameter values
- Deploy database activity monitoring to detect anomalous query patterns or unauthorized data access
- Utilize intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
Monitoring Recommendations
- Enable detailed logging for all requests to /bank/mnotice.php and related banking application endpoints
- Configure database query logging to capture and analyze SQL statements executed against the backend database
- Set up alerts for error responses from the application that may indicate attempted SQL injection exploitation
- Implement real-time monitoring of database user activity for signs of data exfiltration
How to Mitigate CVE-2025-9305
Immediate Actions Required
- Take the affected Online Bank Management System offline or restrict access to trusted networks until patching is possible
- Implement input validation and parameterized queries for the ID parameter in /bank/mnotice.php
- Deploy a web application firewall with SQL injection protection rules as a temporary mitigation
- Review database access logs for signs of prior exploitation and assess data integrity
Patch Information
No official patch has been released by the vendor at this time. Organizations using SourceCodester Online Bank Management System 1.0 should monitor the SourceCodester Resource Portal for security updates. For additional vulnerability details, refer to VulDB #320910.
Workarounds
- Implement prepared statements with parameterized queries in the /bank/mnotice.php file to prevent SQL injection
- Apply strict input validation to reject any non-numeric characters in the ID parameter
- Restrict network access to the banking application to trusted IP addresses only
- Deploy a web application firewall configured to block common SQL injection patterns
# Example Apache mod_security rule to block SQL injection attempts
SecRule ARGS:ID "(\b(union|select|insert|update|delete|drop)\b|'|--|;)" \
"id:1001,phase:2,deny,status:403,msg:'SQL Injection attempt detected in ID parameter'"
