The vulnerability identified as CVE-2017-15993 affects the Zomato Clone Script, a web application designed to replicate the functionality of the popular food delivery platform Zomato. This particular flaw resides within the restaurant-menu.php component of the application, where user input is improperly handled, creating an avenue for malicious actors to execute unauthorized database operations. The vulnerability specifically manifests through the resid parameter, which is used to identify restaurant identifiers within the application's database queries. This SQL injection vulnerability represents a critical security weakness that can be exploited to gain unauthorized access to sensitive data stored within the application's backend database infrastructure.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization practices within the restaurant-menu.php script. When the resid parameter is passed to the application without proper filtering or parameterization, attackers can inject malicious SQL commands that are then executed by the database server. This occurs because the application constructs SQL queries by directly concatenating user-supplied input values without employing prepared statements or other secure coding practices. The vulnerability falls under CWE-89, which specifically addresses SQL injection flaws where untrusted data is incorporated into SQL queries without proper sanitization. Attackers can exploit this weakness to perform various malicious activities including data extraction, modification, or deletion of database records, potentially compromising the entire application's data integrity and confidentiality.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable attackers to escalate their privileges within the application environment. Successful exploitation allows malicious actors to bypass authentication mechanisms, access administrative functions, and potentially gain full control over the application's database layer. This creates a significant risk for businesses relying on the Zomato Clone Script for their food delivery operations, as customer data, restaurant information, payment details, and business-critical records could be compromised. The vulnerability also aligns with ATT&CK technique T1071.005, which describes the use of application layer protocols for data exfiltration and command execution. Organizations using this script face potential regulatory compliance violations and reputational damage if sensitive customer information is exposed through such attacks.
Mitigation strategies for CVE-2017-15993 must focus on implementing proper input validation and parameterized queries throughout the application codebase. Developers should immediately implement prepared statements or parameterized queries to ensure that user input cannot be interpreted as executable SQL code. Additionally, comprehensive input sanitization routines should be deployed to filter out malicious characters and patterns that could be used in injection attacks. Security patches should be applied promptly to address the underlying vulnerability, and access controls should be reviewed to limit database permissions to only necessary functions. Network-level protections such as web application firewalls can provide additional defense-in-depth measures, while regular security audits and penetration testing should be conducted to identify and remediate similar vulnerabilities throughout the application's codebase. Organizations should also implement monitoring solutions to detect anomalous database access patterns that could indicate exploitation attempts.
