CWE ID Description
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.
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 Examination System. It allows attackers to manipulate database queries by injecting malicious input into parameters like query, qtype, sortname, and sortorder. The flaw exists because these inputs are directly concatenated into SQL statements without proper sanitization or authentication checks.

Detection Guidance

To detect this SQL injection vulnerability, inspect the file qsdb/usersdb/brandb/topicsdb/subjectsdb.php for direct SQL query construction using POST parameters query, qtype, sortname, and sortorder without input validation. Use tools like sqlmap to test for SQLi by sending crafted requests to admin endpoints.

Impact Analysis

An attacker could remotely extract sensitive data such as user credentials, password hashes, and other confidential information from the database. Since no authentication is required, anyone with network access can exploit this. The impact includes unauthorized data access and potential further attacks on the system.

Compliance Impact

This vulnerability likely violates compliance requirements such as GDPR (data protection) and HIPAA (health information privacy) due to unauthorized access to sensitive data. Organizations using this system could face legal penalties, fines, and reputational damage for failing to protect personal or health information.

Mitigation Strategies

Immediately apply input validation and parameterized queries to sanitize POST parameters. Restrict database user privileges and avoid using root accounts. Monitor network traffic for suspicious UNION-based payloads targeting the vulnerable endpoints.
