The vulnerability identified as CVE-2019-9762 represents a critical SQL injection flaw within the PHPSHE 1.7 content management system specifically within the payment plugin module. This security weakness exists in the file include/plugin/payment/alipay/pay.php and affects the parameter named id, creating a significant exposure point that allows malicious actors to execute arbitrary database commands without requiring any authentication credentials. The absence of authentication requirements makes this vulnerability particularly dangerous as it can be exploited by anyone with access to the affected system, eliminating the need for prior authorization or privilege escalation.
This SQL injection vulnerability falls under the Common Weakness Enumeration category CWE-89, which specifically addresses SQL injection vulnerabilities that occur when user-supplied data is directly incorporated into SQL queries without proper sanitization or parameterization. The flaw stems from improper input validation within the payment processing module where the id parameter is directly used in database queries without adequate protection mechanisms. Attackers can manipulate the id parameter to inject malicious SQL code that can then be executed by the database server, potentially leading to complete database compromise.
The operational impact of this vulnerability extends beyond simple data theft or modification. Successful exploitation can result in unauthorized access to sensitive customer payment information, financial transaction records, and other confidential data stored within the PHPSHE database. The attacker could potentially escalate privileges, extract complete database schemas, modify or delete critical information, and even establish persistent backdoors within the system. Given that this affects a payment processing module, the financial implications are particularly severe, potentially exposing merchants and customers to fraud and financial loss.
Organizations utilizing PHPSHE 1.7 should immediately implement comprehensive mitigations including input validation and parameterized queries to prevent SQL injection attacks. The recommended approach involves sanitizing all user inputs, implementing proper prepared statements, and applying the latest security patches released by the PHPSHE development team. Additionally, network-level protections such as web application firewalls should be deployed to monitor and block suspicious SQL injection attempts. According to the MITRE ATT&CK framework, this vulnerability maps to the technique T1190 - Exploit Public-Facing Application, highlighting the need for proper input validation and output encoding as defensive measures. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities across the entire application stack, ensuring comprehensive protection against similar attack vectors.
