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 is a SQL injection vulnerability in the Online Faculty Clearance System 1.0. The issue is in the file update_requirement_status.php where the 'haydi' parameter is not properly validated. Attackers can inject malicious SQL queries remotely without authentication, potentially accessing or altering database contents.

Detection Guidance

To detect SQL injection vulnerabilities like CVE-2026-90877, test the 'haydi' parameter in /update_requirement_status.php using tools like SQLmap or Burp Suite. Example SQLmap command: sqlmap -u 'http://target/update_requirement_status.php?haydi=1' --batch. Check for error messages or delays in responses indicating SQL injection.

Impact Analysis

Exploitation could lead to unauthorized database access, data tampering, sensitive data leakage, system control takeover, and service disruption. Attackers may extract, modify, or delete data, or even take over the entire system.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection and security. GDPR mandates protection against unauthorized data access, while HIPAA requires safeguards for sensitive health data. Exploitation could result in non-compliance, legal penalties, and reputational damage.

Mitigation Strategies

Immediately apply input validation to sanitize the 'haydi' parameter. Replace dynamic SQL queries with prepared statements. Restrict database user permissions to least privilege. Monitor logs for suspicious activity. Consider temporarily disabling the affected endpoint if a patch is unavailable.
