CVE-2009-0462 in ClickCart
Summary
by MITRE
Multiple SQL injection vulnerabilities in customer_login_check.asp in ClickTech ClickCart 6.0 allow remote attackers to execute arbitrary SQL commands via (1) the txtEmail parameter (aka E-MAIL field) or (2) the txtPassword parameter (aka password field) to customer_login.asp. NOTE: some of these details are obtained from third party information.

The vulnerability identified as CVE-2009-0462 represents a critical SQL injection flaw within the ClickTech ClickCart 6.0 e-commerce platform, specifically affecting the customer_login_check.asp component. This vulnerability exposes the system to remote code execution attacks through improper input validation in the authentication process, making it a severe threat to web application security. The flaw exists in the way the application handles user credentials during login attempts, where user-supplied data is directly incorporated into SQL queries without adequate sanitization or parameterization. The vulnerability affects two primary input fields: txtEmail and txtPassword, which correspond to the email and password fields in the customer login interface, creating multiple attack vectors for malicious actors to exploit.
The technical implementation of this vulnerability stems from the application's failure to properly escape or parameterize user input before incorporating it into database queries. When a user submits login credentials through customer_login.asp, the submitted values are passed directly to customer_login_check.asp without appropriate validation or sanitization measures. This allows attackers to inject malicious SQL code that can manipulate the database query execution flow, potentially leading to unauthorized access, data extraction, or complete system compromise. The vulnerability is classified under CWE-89, which specifically addresses SQL injection flaws where untrusted data is used in SQL commands without proper validation or escaping mechanisms. The attack vector is particularly dangerous as it occurs during the authentication process, meaning that an attacker could potentially bypass authentication entirely or gain access to sensitive customer data stored in the database.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable attackers to escalate privileges, modify customer accounts, or even gain administrative access to the entire e-commerce platform. Successful exploitation could result in the exposure of customer personal information, credit card details, and other sensitive data, potentially leading to identity theft, financial fraud, and significant regulatory compliance violations. The vulnerability affects the confidentiality, integrity, and availability of the web application, creating a triad of security concerns that can severely impact business operations and customer trust. Organizations using ClickCart 6.0 would face potential legal consequences, regulatory penalties, and reputational damage if such vulnerabilities were exploited, as they would be deemed to have inadequate security controls in place for protecting customer data. The attack surface is particularly concerning because authentication is a fundamental component of any web application, making this vulnerability a critical target for exploitation.
Mitigation strategies for this vulnerability should focus on implementing proper input validation, parameterized queries, and secure coding practices throughout the application. Organizations should immediately upgrade to a patched version of ClickCart or implement web application firewall rules to detect and block SQL injection attempts. The remediation process must include thorough code review to ensure all database queries properly utilize parameterized statements or prepared statements, which directly addresses the underlying CWE-89 vulnerability. Additionally, implementing proper error handling that does not reveal database structure information to users can prevent attackers from gaining intelligence about the database schema. Security measures should also include monitoring for unusual login patterns and implementing rate limiting to prevent automated attack attempts. According to ATT&CK framework, this vulnerability maps to T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS), as attackers would typically use these techniques to probe and exploit web applications. Organizations should also consider implementing database activity monitoring and regular penetration testing to identify similar vulnerabilities in their web applications.
