The vulnerability identified as CVE-2017-17575 affects FS Groupon Clone version 1.0, a web application designed to replicate group buying functionality similar to popular platforms. This software implementation contains critical security flaws that enable unauthorized users to manipulate database queries through specifically crafted input parameters. The vulnerability exists within the application's handling of user-supplied data in two distinct endpoints: item_details.php and vendor_details.php, both of which accept an id parameter that is improperly validated and sanitized.
The technical flaw represents a classic SQL injection vulnerability categorized under CWE-89, which occurs when user input is directly incorporated into SQL commands without proper sanitization or parameterization. When attackers submit malicious input through the id parameter in either item_details.php or vendor_details.php, the application fails to properly escape or validate the input before incorporating it into database queries. This allows threat actors to inject arbitrary SQL code that can be executed within the database context, potentially enabling full database compromise.
The operational impact of this vulnerability is severe and multifaceted, as it provides attackers with unauthorized access to sensitive data stored within the application's database. Successful exploitation could result in data theft, data manipulation, privilege escalation, and potentially full system compromise. Attackers could extract customer information, vendor details, transaction records, and other confidential data that the application stores. The vulnerability also enables attackers to modify or delete database content, disrupt service availability, and potentially establish persistent backdoors within the system. From an attack framework perspective, this vulnerability aligns with ATT&CK technique T1071.004 for application layer protocol manipulation and T1046 for network service scanning to identify vulnerable endpoints.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and parameterized queries. The application code must be updated to use prepared statements or parameterized queries for all database interactions, ensuring that user input cannot alter the intended structure of SQL commands. Additionally, input validation should be implemented at multiple layers including application-level sanitization, output encoding, and proper error handling that does not reveal database structure information. Security measures should include implementing web application firewalls, conducting regular security code reviews, and applying the latest security patches to the application framework. Organizations should also consider implementing database access controls, monitoring for unusual database activity, and establishing proper network segmentation to limit the potential impact of successful exploitation. The vulnerability demonstrates the critical importance of secure coding practices and proper input handling in preventing database-level attacks that can have far-reaching consequences for both application integrity and user data protection.
