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.

Executive Summary

This vulnerability is a SQL injection flaw in the Online Faculty Clearance System 1.0. It exists in the file /delete_requirement.php where the 'ID' argument is improperly validated. Attackers can manipulate this input to inject malicious SQL queries, potentially accessing or altering database contents without authentication.

Detection Guidance

To detect SQL injection vulnerabilities like CVE-2026-90876, monitor web server logs for unusual requests targeting /delete_requirement.php with suspicious parameters. Use tools like SQLmap to test for injection by sending payloads such as ' OR 1=1 -- or '; DROP TABLE users;--. Check for error messages in responses that indicate SQL syntax issues.

Impact Analysis

Exploitation could lead to unauthorized database access, data tampering, sensitive information leakage, and potential system compromise. Attackers might extract or modify confidential data, disrupt system operations, or gain control over the affected application.

Compliance Impact

This vulnerability likely violates compliance requirements such as GDPR (data protection) and HIPAA (health information security) due to unauthorized data access or leakage risks. Organizations may face legal penalties, reputational damage, and mandatory breach notifications if exploited.

Mitigation Strategies

Immediately update the application to use prepared statements with parameterized queries for all database interactions. Implement strict input validation to sanitize the 'id' parameter in /delete_requirement.php. Restrict database user permissions to the minimum required. Conduct a security audit to identify other potential vulnerabilities and apply patches as needed.
