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. The flaw exists in the file /reviewer_0/admins/assessments/databank/btn_functions.php when the ID parameter is manipulated with action=remove. User input for the ID is directly used in SQL queries without validation, allowing attackers to inject malicious SQL code.

Detection Guidance

To detect this SQL injection vulnerability, you can test the affected URL parameter with common SQL injection payloads. Use tools like curl or browser extensions to send requests to /reviewer_0/admins/assessments/databank/btn_functions.php?action=remove&id=1. Test with payloads such as ' OR '1'='1, ' OR 1=1 --, or time delays like id=1 AND (SELECT * FROM (SELECT(SLEEP(5)))a). If the application responds abnormally or delays, it may indicate SQL injection.

  • Use automated scanners like SQLmap: sqlmap -u 'http://target/reviewer_0/admins/assessments/databank/btn_functions.php?action=remove&id=1' --batch.
Impact Analysis

This vulnerability allows remote attackers to execute unauthorized database access, manipulate data, leak sensitive information, and potentially compromise the system without authentication. Attackers can use techniques like boolean-based blind, error-based, time-based blind, or stacked queries to exploit it.

Compliance Impact

This vulnerability could lead to unauthorized data access or manipulation, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Non-compliance may result in legal penalties, fines, or reputational damage.

Mitigation Strategies

Immediately update the application to use prepared statements with parameter binding for all database queries. Ensure user input for the id parameter is strictly validated and sanitized. Remove unnecessary database permissions and restrict access to sensitive data. Conduct a full security audit of the application to identify similar issues.
