The vulnerability identified as CVE-2008-5772 represents a critical security flaw in ASPSiteWare RealtyListings versions 1.0 and 2.0 that exposes the application to remote SQL injection attacks. This vulnerability resides in the web application's handling of user input parameters, specifically targeting two distinct endpoints within the software's architecture. The affected parameters iType in type.asp and iPro in detail.asp demonstrate a fundamental lack of proper input validation and sanitization mechanisms that would normally protect against malicious SQL command injection attempts.
The technical implementation of this vulnerability stems from the application's failure to properly escape or filter user-supplied input before incorporating it into SQL query constructions. When an attacker submits malicious input through either the iType or iPro parameters, the application directly concatenates this unvalidated data into database queries without appropriate sanitization measures. This design flaw allows attackers to manipulate the intended SQL execution flow by injecting malicious SQL syntax that can alter the query's behavior, potentially enabling data extraction, modification, or deletion operations. The vulnerability operates at the application layer and requires no special privileges to exploit, making it particularly dangerous as it can be leveraged by any remote attacker with access to the affected web interface.
The operational impact of this vulnerability extends beyond simple data exposure, as it provides attackers with the capability to perform arbitrary SQL command execution within the database context. This could result in complete database compromise, unauthorized data access, data manipulation, or even potential privilege escalation within the database system. The vulnerability affects the integrity and confidentiality of all real estate listing data managed by the ASPSiteWare application, potentially exposing sensitive customer information, property details, and business data to unauthorized parties. The remote nature of the attack means that exploitation can occur from anywhere on the internet without requiring physical access to the target system, significantly expanding the attack surface and potential impact.
Security professionals should consider this vulnerability in the context of CWE-89 which specifically addresses SQL injection flaws, and align it with ATT&CK techniques such as T1071.004 for application layer protocol and T1046 for network service scanning. Organizations should implement immediate mitigations including input validation, parameterized queries, and proper output encoding to prevent malicious SQL injection attempts. The recommended remediation strategy involves implementing proper input sanitization techniques, utilizing prepared statements or parameterized queries, and conducting comprehensive code reviews to identify similar vulnerabilities throughout the application codebase. Additionally, network segmentation and web application firewalls should be deployed to limit the potential impact of such vulnerabilities while permanent fixes are implemented.
