CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

CVE-2026-90526 is a SQL injection vulnerability in the School Registration and Fee System 1.0. It affects the file /bilal/save_class.php where the 'Category' parameter is improperly validated. Attackers can inject malicious SQL queries without authentication, leading to unauthorized database access and data tampering.

Detection Guidance

To detect SQL injection vulnerabilities like CVE-2026-90526, inspect the /bilal/save_class.php file for improper input handling of the 'category' parameter. Use tools like SQLmap to test for SQL injection by sending payloads such as ' OR 1=1 -- or testing for time delays with sleep(5). Check web server logs for unusual queries or errors indicating SQL syntax issues.

Impact Analysis

This vulnerability allows attackers to access sensitive data, modify or delete database records, and potentially take control of the system. It could also disrupt services by causing database errors or crashes. Exploitation does not require authentication, making it easier for attackers to target vulnerable systems.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA due to unauthorized data access or leakage. GDPR requires protecting personal data, while HIPAA mandates safeguarding health information. A successful exploit may result in data breaches, triggering legal penalties and reputational damage.

Mitigation Strategies

Immediately update the application to use prepared statements for all database queries. Implement strict input validation to sanitize the 'category' parameter. Restrict database user permissions to limit potential damage. Conduct a security audit to identify other vulnerable components and apply patches as needed.
