SQL Injection Vulnerability in StudentManagementSystem (CVE-2026-9474)

A SQL injection vulnerability, identified as CVE-2026-9474, has been discovered in the StudentManagementSystem application, affecting versions up to commit cb2f558ddf8d19396de0f92abf2d224d46a0a203. The vulnerability is located in the confirm_logged_in function of the /studentdel.php file. An attacker can remotely exploit this vulnerability by manipulating the ID argument passed to the function, enabling them to inject and execute arbitrary SQL commands. While the vulnerability has been publicly disclosed, the vendor has not yet responded to the report. Given the continuous delivery model, specific affected or updated version details are unavailable, increasing the risk for deployments relying on this system.

Attack Chain

1. An attacker identifies an instance of StudentManagementSystem running a vulnerable version (<= cb2f558ddf8d19396de0f92abf2d224d46a0a203).
2. The attacker crafts a malicious HTTP request targeting the /studentdel.php endpoint.
3. The crafted request includes a manipulated ID parameter containing SQL injection payloads (e.g., 1' OR '1'='1).
4. The confirm_logged_in function in /studentdel.php receives the tainted ID parameter without proper sanitization.
5. The application executes a SQL query that incorporates the attacker-controlled ID value.
6. The injected SQL code modifies the original query, allowing the attacker to bypass authentication or access unauthorized data.
7. The application returns sensitive data or allows the attacker to perform administrative actions.
8. The attacker gains unauthorized access to the database, potentially exfiltrating data or modifying application settings.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2026-9474) can lead to unauthorized access to sensitive student data, modification of records, or complete database compromise. The lack of versioning information due to the rolling release nature of the application makes patching and mitigation challenging. The vulnerability allows attackers to bypass authentication and potentially escalate privileges. While the exact number of affected installations is unknown, any system running a vulnerable version is at risk of data breaches and service disruption.

Recommendation

• Deploy the provided Sigma rule to your SIEM to detect potential SQL injection attempts targeting /studentdel.php and the ID parameter.
• Implement input validation and sanitization for the ID parameter in the confirm_logged_in function within /studentdel.php to prevent SQL injection.
• Monitor web server logs for suspicious requests to /studentdel.php containing SQL injection payloads.
• Consider using a web application firewall (WAF) to filter out malicious requests targeting the vulnerable endpoint.
• Follow secure coding practices to prevent SQL injection vulnerabilities in future releases of StudentManagementSystem.
• Apply any available patches or updates released by the vendor as soon as they become available, even without version numbers.
