The CVE-2010-4635 vulnerability represents a critical SQL injection flaw within the Site2Nite Vacation Rental platform's detail.asp component. This vulnerability specifically targets the ID parameter handling mechanism, creating an exploitable entry point for malicious actors to manipulate database queries. The affected application serves vacation rental listings and provides users with detailed property information through the vulnerable.asp page. The flaw stems from inadequate input validation and sanitization practices within the web application's backend processing logic, allowing attackers to inject malicious SQL code through the ID parameter.
The technical exploitation of this vulnerability occurs when user-supplied input from the ID parameter is directly concatenated into SQL query strings without proper sanitization or parameterization. This design flaw enables attackers to craft malicious input that alters the intended query execution flow, potentially allowing them to extract sensitive data, modify database records, or even gain unauthorized administrative access to the underlying database system. The vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses in software applications. Attackers can leverage this vulnerability to perform unauthorized database operations including data exfiltration, data manipulation, and privilege escalation attacks that compromise the entire database infrastructure.
The operational impact of CVE-2010-4635 extends beyond immediate data compromise to encompass broader security implications for the vacation rental platform and its users. Successful exploitation could result in unauthorized access to customer information, property listings, reservation details, and potentially financial data stored within the database. This vulnerability creates a persistent threat vector that attackers can utilize repeatedly, as the flaw exists in the core database interaction logic rather than being dependent on specific conditions or user actions. The vulnerability also violates fundamental security principles outlined in the OWASP Top Ten, particularly the SQL injection category that consistently ranks among the most critical web application security risks.
Organizations affected by this vulnerability should implement immediate mitigations including input validation and parameterized query implementation across all database interaction points. The recommended approach involves transitioning from dynamic query construction to prepared statements or parameterized queries that separate SQL code from user input data. Additionally, comprehensive input sanitization should be implemented to filter or escape potentially malicious characters before processing user-supplied data. Security controls should include web application firewalls that can detect and block suspicious SQL injection patterns, along with regular security testing and code reviews to identify similar vulnerabilities within the application codebase. The remediation process should follow NIST cybersecurity frameworks and align with industry best practices for secure coding standards as outlined in the ATT&CK framework's database access techniques.
