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

This is a SQL injection vulnerability in Online Reviewer Management System 1.0. It affects the file /reviewer_0/admins/assessments/course/btn_functions.php when the Course parameter is manipulated. The lack of input validation allows attackers to inject malicious SQL queries into the database. This can lead to unauthorized access, data tampering, and system compromise without authentication.

Detection Guidance

To detect SQL injection vulnerabilities like CVE-2026-93959, you can use tools such as SQLmap to test the affected parameter. Example command: sqlmap -u 'http://target.com/reviewer_0/admins/assessments/course/btn_functions.php?action=course&Course=1' --batch. Alternatively, manually test with payloads like ' OR 1=1 -- or ' OR '1'='1.

Check web server logs for unusual queries containing SQL syntax errors or suspicious input patterns in the Course parameter. Monitor database logs for unexpected queries or unauthorized access attempts.

Impact Analysis

An attacker could exploit this to access sensitive data, alter or delete database records, or gain control of the system. Since no authentication is required, the risk is high for data breaches or system takeovers. Attackers may use techniques like boolean-based blind or time-based SQL injection to extract information.

Compliance Impact

This vulnerability likely violates GDPR and HIPAA due to unauthorized data access and potential data breaches. GDPR requires protection of personal data, while HIPAA mandates safeguards for health information. Exploitation could lead to legal penalties, fines, and reputational damage for non-compliance.

Mitigation Strategies

Immediately update the application to the latest patched version if available. If not, implement input validation to sanitize the Course parameter. Use prepared statements with parameter binding for all database queries.

Restrict database user permissions to the minimum required. Disable error-based SQL injection details in error messages. Conduct a security audit to identify other potential vulnerabilities.
