The vulnerability identified as CVE-2006-5955 represents a critical sql injection flaw within the 20/20 DataShed real estate listing system, specifically affecting the listings.asp component. This vulnerability resides in the application's handling of user input through the itemID parameter, which is processed without adequate sanitization or validation mechanisms. The flaw enables remote attackers to manipulate the underlying database queries by injecting malicious sql code through the targeted parameter, potentially compromising the entire database infrastructure.
The technical exploitation of this vulnerability occurs when the application fails to properly escape or validate the itemID parameter value before incorporating it into sql statements. This lack of input validation creates an environment where attacker-controlled data can be interpreted as part of the sql command rather than as literal data, allowing for arbitrary sql command execution. The vulnerability specifically targets the listings.asp script which likely processes real estate property listings and retrieves data from a backend database, making the attack surface particularly dangerous for sensitive property information.
From an operational perspective, this vulnerability poses significant risks to the confidentiality, integrity, and availability of the real estate listing system. Attackers could potentially extract sensitive customer data, modify property listings, delete database entries, or even escalate privileges to gain administrative access to the database server. The impact extends beyond simple data theft as the vulnerability could enable complete system compromise, especially if the application runs with elevated database permissions. Organizations relying on this system for managing real estate listings face potential exposure of proprietary property data, customer information, and business-critical records.
The vulnerability aligns with CWE-89 which categorizes sql injection as a common weakness in software applications, and maps to ATT&CK technique T1190 for exploiting vulnerabilities in applications. Mitigation strategies should include implementing proper input validation and parameterized queries to prevent sql injection attacks. Organizations should immediately apply patches if available, implement web application firewalls to detect malicious sql injection attempts, and conduct thorough code reviews to identify similar vulnerabilities in other application components. Database access controls should be reviewed to ensure applications use least privilege principles, and regular security assessments should be performed to identify and remediate similar vulnerabilities in the application codebase.
