The vulnerability identified as CVE-2019-3577 affects Waimai Super Cms version 20150505, specifically within the ProductAction.class.php file located in the web/Lib/Action/ directory. This flaw represents a critical security weakness that enables attackers to execute blind SQL injection attacks against the application's database layer. The vulnerability manifests when the application processes the id[0] parameter through the /product URI endpoint without adequate input validation or sanitization measures.
The technical implementation of this vulnerability stems from improper handling of user-supplied input within the ProductAction class. When a malicious actor submits a crafted id[0] parameter value to the /product endpoint, the application fails to properly escape or validate the input before incorporating it into SQL query constructions. This creates an opportunity for attackers to manipulate the underlying database queries through carefully constructed payloads that can extract information through blind SQL injection techniques. The vulnerability is classified as blind SQL injection because the application does not directly expose database query results to the user, requiring attackers to infer information through indirect means such as response timing variations or conditional responses.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with potential access to sensitive customer information, business data, and system configurations. Attackers can leverage this vulnerability to enumerate database schemas, extract user credentials, access confidential business records, and potentially escalate privileges within the application. The affected Waimai Super Cms platform could suffer significant financial losses, regulatory penalties, and reputational damage if exploited successfully. This vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws, and represents a clear violation of secure coding practices that should prevent user input from directly influencing database query structures.
Mitigation strategies for this vulnerability should include immediate implementation of input validation and parameterized queries to prevent user input from being interpreted as SQL commands. The application should employ proper sanitization techniques and implement proper access controls to limit the impact of potential exploitation. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for suspicious activities targeting the affected URI endpoints. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities within the application codebase, and developers should follow secure coding guidelines such as those outlined in the OWASP Top Ten project. Additionally, the affected version of Waimai Super Cms should be updated to a patched release or replaced with a more secure alternative to eliminate this attack vector entirely. The vulnerability demonstrates the importance of proper input validation and the principle of least privilege in web application security, as outlined in the MITRE ATT&CK framework's database access techniques.
