The vulnerability described in CVE-2005-2062 represents a critical SQL injection flaw affecting ActiveBuyAndSell version 6.2, a web-based e-commerce platform designed for buying and selling services. This vulnerability stems from inadequate input validation and sanitization within multiple ASP pages of the application, creating exploitable entry points that allow remote attackers to inject malicious SQL commands into the database layer. The flaw manifests across several distinct endpoints including default.asp, buyersend.asp, admin.asp, advertiserstart.asp, buyer.asp, and search.asp, each presenting unique attack vectors that collectively demonstrate the widespread nature of the security weakness. The vulnerability is classified under CWE-89, which specifically addresses SQL injection flaws, and aligns with ATT&CK technique T1190, which covers exploitation of vulnerabilities in web applications.
The technical implementation of this vulnerability occurs when user-supplied input from the catid parameter in default.asp and buyersend.asp is directly concatenated into SQL query strings without proper sanitization or parameterization. Similarly, the Administrator ID field in admin.asp, email fields in advertiserstart.asp and buyer.asp, and the keyword field in search.asp all suffer from identical input handling issues. Attackers can exploit these weaknesses by crafting malicious SQL payloads that manipulate the database queries, potentially gaining unauthorized access to sensitive information, modifying database records, or even executing administrative commands on the underlying database system. The impact extends beyond simple data theft as these vulnerabilities can enable complete system compromise and unauthorized access to user accounts, financial data, and business-critical information.
The operational impact of this vulnerability is severe and multifaceted, potentially allowing attackers to perform unauthorized data access, modification, and deletion operations across the entire ActiveBuyAndSell platform. Remote attackers could extract confidential information including user credentials, customer data, transaction records, and administrative details, while also potentially gaining the ability to modify or delete critical database content. The vulnerability's presence in multiple application endpoints increases the attack surface and reduces the effectiveness of partial mitigations, as exploitation could occur through various entry points depending on the attacker's objectives and available information. Organizations running this software would face potential regulatory compliance violations, financial losses, reputation damage, and legal consequences from data breaches resulting from these unpatched vulnerabilities.
Mitigation strategies for CVE-2005-2062 must focus on implementing proper input validation and parameterized queries throughout the application codebase. The most effective approach involves replacing direct string concatenation of user input with prepared statements or parameterized queries that separate SQL commands from data, thereby preventing malicious input from being interpreted as executable SQL code. Additionally, implementing proper input sanitization routines, enforcing strict parameter validation, and applying the principle of least privilege to database connections can significantly reduce the attack surface. Organizations should also consider implementing web application firewalls, input filtering mechanisms, and regular security code reviews to prevent similar vulnerabilities from emerging in future development cycles. The vulnerability highlights the critical importance of following secure coding practices and adhering to industry standards such as OWASP Top Ten and NIST guidelines for preventing SQL injection attacks.
