The vulnerability identified as CVE-2017-17951 affects PHP Scripts Mall PHP Multivendor Ecommerce software, representing a critical security flaw that exposes the application to unauthorized data access and potential system compromise. This vulnerability specifically manifests through the shopping-cart.php script where the cusid parameter fails to properly validate or sanitize user input, creating an avenue for malicious actors to execute unauthorized database operations. The flaw exists within the application's input handling mechanisms, where user-supplied data intended for customer identification is directly incorporated into database queries without adequate protection against injection attacks.
The technical nature of this vulnerability aligns with CWE-89, which categorizes SQL injection flaws as weaknesses in software that allows attackers to manipulate database queries through malicious input. In this case, the cusid parameter in shopping-cart.php serves as the attack vector where an attacker can inject malicious SQL code that gets executed by the database server. When the application processes the cusid parameter without proper input validation or parameterization, it creates an environment where attackers can extract sensitive information, modify database records, or even execute administrative commands on the underlying database system. The vulnerability represents a classic example of insufficient input sanitization where user-controllable data flows directly into SQL command construction without appropriate escaping or parameter binding.
The operational impact of this vulnerability extends beyond simple data theft, potentially allowing attackers to gain full administrative control over the ecommerce platform's database infrastructure. An attacker could exploit this weakness to access customer information including personal details, payment records, and purchase histories, which would constitute a significant privacy breach. Additionally, the vulnerability could enable attackers to modify product listings, manipulate pricing information, or even delete critical business data, leading to both financial losses and reputational damage for the organization operating the affected platform. The risk is particularly elevated in ecommerce environments where databases contain sensitive transactional data and customer credentials that could be leveraged for further attacks within the broader network infrastructure.
Mitigation strategies for this vulnerability should prioritize immediate patching of the affected software version to address the SQL injection flaw in the shopping-cart.php script. Organizations should implement proper input validation techniques including parameterized queries or prepared statements to prevent malicious SQL code from being executed. The implementation of web application firewalls and input sanitization mechanisms can provide additional layers of protection against similar attacks. Security teams should conduct comprehensive code reviews focusing on all database interaction points within the application to identify and remediate similar vulnerabilities. According to ATT&CK framework tactic TA0006, this vulnerability falls under credential access and data manipulation categories, requiring organizations to monitor for unusual database access patterns and implement proper database activity logging. Regular security assessments and penetration testing should be conducted to ensure that similar injection vulnerabilities are not present in other components of the ecommerce platform, with particular attention to parameters handling customer identifiers and administrative functions.
