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.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA due to unauthorized data access or exposure. GDPR requires protection of personal data, while HIPAA mandates safeguards for health-related information. A breach could result in legal penalties and reputational damage.

Mitigation Strategies

Immediately update the application to the latest patched version if available. Apply input validation and parameterized queries to sanitize the course argument in /admin/modal_add_course.php. Restrict database user permissions to limit damage from potential SQL injection. Monitor network traffic for suspicious activity targeting this file.
