The vulnerability identified as CVE-2019-9626 affects PHPSHE version 1.7 and represents a critical sql injection flaw in the cart module that can be exploited through the pintuan_id parameter. This vulnerability exists within the module/index/cart.php file and can be leveraged to manipulate the application's database operations by redirecting execution to index.php. The flaw arises from insufficient input validation and sanitization of user-supplied data passed through the pintuan_id parameter, creating an attack surface that allows malicious actors to inject arbitrary sql commands into the backend database. This type of vulnerability falls under the category of CWE-89 sql injection as defined by the common weakness enumeration, which specifically addresses the improper handling of sql commands within applications. The attack vector is particularly concerning as it targets the shopping cart functionality, which typically handles sensitive user data including personal information and transaction details.
The operational impact of this vulnerability extends beyond simple data extraction as it provides attackers with the capability to perform unauthorized database operations including data modification, deletion, and unauthorized access to sensitive user information. The exploitation process involves crafting malicious input parameters that bypass the application's input validation mechanisms and directly influence the sql query execution path. Attackers can leverage this vulnerability to escalate privileges, gain persistent access to the database, or even compromise the entire web application infrastructure. The vulnerability's location within the cart module also means that successful exploitation could lead to financial fraud, user data breaches, and potential system compromise. According to the mitre att&ck framework, this vulnerability maps to the technique T1071.004 application layer protocol and T1190 exploit public-facing application, as it represents a publicly exposed web application vulnerability that can be exploited without requiring privileged access. The vulnerability can be classified as a persistent threat due to its potential for long-term access and data exfiltration.
Mitigation strategies for CVE-2019-9626 should focus on implementing proper input validation and parameterized queries to prevent sql injection attacks. Organizations should immediately update to the latest version of PHPSHE where this vulnerability has been patched, or implement proper input sanitization measures including the use of prepared statements and proper escaping of user-supplied data. The implementation of web application firewalls and intrusion detection systems can provide additional layers of protection by monitoring for suspicious sql injection patterns. Security teams should also conduct comprehensive code reviews to identify similar vulnerabilities within the application's codebase and ensure that all user inputs are properly validated before being processed. Regular security assessments and penetration testing should be performed to verify that the implemented mitigations are effective and to identify any additional attack vectors that may exist within the application. The vulnerability serves as a reminder of the critical importance of secure coding practices and the need for continuous security monitoring to protect against evolving threats in web applications.
