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.

Executive Summary

This vulnerability is an SQL injection flaw in SEMCMS up to version 5.0, specifically in the SEMCMS_Download.php file. It allows attackers to manipulate database queries remotely by injecting malicious SQL code through an unknown function. The exploit is publicly available and was disclosed despite the vendor not responding.

Detection Guidance

To detect this SQL injection vulnerability in SEMCMS up to 5.0, use the sqlmap tool with the provided command: python sqlmap.py -r 2.txt -dbs. This requires a request file (2.txt) capturing the vulnerable AID parameter in the Download Management section.

Impact Analysis

This vulnerability could allow unauthorized access to sensitive data, manipulation or deletion of database records, and potential takeover of the affected system. Attackers could extract confidential information or alter data without proper authentication.

Compliance Impact

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

Mitigation Strategies

Immediate mitigation steps include updating SEMCMS to the latest version beyond 5.0, applying input validation for the AID parameter, and restricting database access permissions. Since the vendor did not respond, consider disabling the Download Management section if updates are unavailable.
