Cyber-III Student-Management-System SQL Injection Vulnerability

A SQL injection vulnerability, identified as CVE-2026-5669, has been discovered in Cyber-III Student-Management-System. The vulnerability resides within the /login.php file, specifically affecting the handling of the Password parameter. Attackers can exploit this vulnerability remotely to inject malicious SQL code, potentially gaining unauthorized access to sensitive data or manipulating the application's database. The exploit is publicly available, increasing the risk of widespread exploitation. The affected product uses rolling releases; therefore, specific affected and updated versions are not available. The project has been notified of the vulnerability but has not yet responded.

Attack Chain

1. The attacker identifies a Cyber-III Student-Management-System instance accessible over the network.
2. The attacker sends a crafted HTTP POST request to /login.php, targeting the Password parameter.
3. The Password parameter contains a malicious SQL payload designed to bypass authentication or extract data.
4. The application fails to properly sanitize or validate the Password parameter before using it in a SQL query.
5. The injected SQL code is executed against the application's database.
6. The attacker successfully authenticates without valid credentials or retrieves sensitive data, such as user credentials or student records.
7. The attacker uses the compromised credentials or data to further compromise the system or other connected systems.
8. The attacker may exfiltrate sensitive data, modify records, or disrupt system operations.

Impact

Successful exploitation of this SQL injection vulnerability can lead to unauthorized access to sensitive student data, including personal information, grades, and financial records. Attackers could potentially modify or delete data, disrupt system operations, or gain control of the entire Student-Management-System. Given the lack of specific version information and the public availability of the exploit, organizations using Cyber-III Student-Management-System are at immediate risk.

Recommendation

• Inspect web server logs for suspicious POST requests to /login.php containing SQL injection payloads (see example Sigma rule below).
• Implement input validation and sanitization on the Password parameter in /login.php to prevent SQL injection (reference CVE-2026-5669).
• Monitor database logs for unauthorized access attempts or data modification originating from the web server (requires database auditing).
• Deploy the Sigma rules in this brief to your SIEM and tune for your environment.
