The vulnerability identified as CVE-2006-6342 represents a critical security flaw in the KLF-DESIGN (Kim L. Fraser) KLF-REALTY web application, specifically affecting the search_listing.asp and detail.asp pages. This vulnerability stems from inadequate input validation and improper parameter handling within the application's database interaction mechanisms, creating multiple entry points for malicious SQL injection attacks. The affected parameters include category and agent in search_listing.asp, as well as property_id in detail.asp, all of which are directly processed without proper sanitization or parameterization.
The technical exploitation of this vulnerability occurs through the manipulation of HTTP request parameters that are subsequently concatenated into SQL query strings without adequate filtering or escaping mechanisms. When attackers submit malicious input through these parameters, the application fails to distinguish between legitimate user data and potentially harmful SQL commands. This flaw directly maps to CWE-89, which categorizes SQL injection vulnerabilities as a critical weakness in application security where untrusted data is incorporated into SQL commands without proper validation or escaping. The vulnerability exists in the application's input processing layer where user-supplied data flows directly into database queries without appropriate security controls.
From an operational perspective, this vulnerability presents a severe risk to the confidentiality, integrity, and availability of the affected web application and its underlying database systems. Remote attackers can potentially execute arbitrary SQL commands with the privileges of the database user account, leading to unauthorized data access, modification, or deletion. The impact extends beyond simple data theft as attackers may escalate privileges, extract sensitive information such as user credentials, customer data, or property listings, and potentially gain persistence within the network infrastructure. The vulnerability affects the application's core functionality by compromising the integrity of search and property detail features, which are fundamental to the real estate listing platform's operations.
The attack surface for this vulnerability is particularly concerning given that it affects multiple pages within the application, increasing the likelihood of successful exploitation. The search_listing.asp page provides attackers with multiple vectors through category and agent parameters, while the detail.asp page offers additional access through property_id, creating a comprehensive attack surface for SQL injection. According to ATT&CK framework category T1190, this vulnerability represents a technique for exploiting vulnerabilities in web applications to gain unauthorized access to backend systems. Mitigation strategies should include implementing proper input validation and parameterized queries, applying the principle of least privilege for database accounts, and conducting regular security assessments. Organizations should also consider implementing web application firewalls and input sanitization measures to prevent malicious SQL commands from reaching the database layer, while ensuring that all application parameters are properly escaped or parameterized before database interaction occurs.
