The vulnerability identified as CVE-2022-40933 affects the Online Pet Shop We App version 1.0 developed by oretnom23, representing a critical security flaw that exposes the application to unauthorized data access and manipulation. This vulnerability resides within the Master.php file at the endpoint /pet_shop/classes/Master.php?f=delete_order,id which handles order deletion functionality. The application fails to properly sanitize user input parameters, creating an environment where malicious actors can inject arbitrary SQL commands through the delete_order parameter, potentially compromising the entire database infrastructure.
This SQL injection vulnerability falls under CWE-89 which categorizes improper neutralization of special elements used in an SQL command, making it a classic and dangerous attack vector that allows adversaries to execute unauthorized database operations. The flaw specifically manifests when the application processes the id parameter within the delete_order function without adequate input validation or parameterized query usage. Attackers can exploit this weakness to perform unauthorized data retrieval, modification, or deletion operations, potentially gaining access to sensitive customer information, order details, and other critical business data stored within the database. The vulnerability is particularly concerning as it directly impacts the core functionality of order management within the pet shop application, potentially disrupting business operations and exposing confidential information.
The operational impact of this vulnerability extends beyond simple data exposure, as it provides attackers with the capability to manipulate the entire order processing system. Successful exploitation could lead to complete database compromise, allowing threat actors to extract customer personal information, financial details, and transaction records. The vulnerability also enables potential denial of service conditions where attackers might delete critical order data, disrupting business operations and potentially causing financial losses. According to ATT&CK framework technique T1071.005, this vulnerability represents a network protocol abuse where attackers leverage SQL injection to manipulate database communications, while T1213.002 covers data from information repositories, indicating the potential for extensive data extraction and modification capabilities. The attack surface is particularly narrow but critical, as it requires only knowledge of the specific endpoint and parameter structure to exploit.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and parameterized queries throughout the application codebase. The development team must immediately replace direct SQL query concatenation with prepared statements or parameterized queries to prevent user input from being interpreted as executable SQL code. Input sanitization measures should be implemented at multiple layers including application-level validation, database-level filtering, and web application firewall rules to block suspicious payloads. Additionally, the application should implement proper access controls and authentication mechanisms to limit who can access the delete_order endpoint, ensuring that only authorized personnel can perform order deletion operations. Regular security testing including automated vulnerability scanning and manual penetration testing should be conducted to identify and remediate similar vulnerabilities throughout the application lifecycle. The implementation of proper error handling mechanisms is also crucial to prevent information leakage that could aid attackers in further exploiting the system, while regular security updates and patches should be maintained to address any newly discovered vulnerabilities in the application dependencies and underlying database systems.
