The vulnerability identified as CVE-2005-4018 represents a critical sql injection flaw within the landshop real estate commerce system version 0.6.3 and earlier installations. This vulnerability exists in the ls.php script which serves as a core component for handling search functionality within the real estate platform. The flaw stems from insufficient input validation and sanitization of user-supplied parameters that are directly incorporated into sql query constructions without proper escaping or parameterization mechanisms. The affected parameters include start, search_order, search_type, search_area, and keyword fields, all of which can be manipulated by remote attackers to inject malicious sql code into the backend database queries.
From a technical perspective this vulnerability maps directly to CWE-89 which specifically addresses sql injection vulnerabilities where untrusted data is incorporated into sql commands without proper validation or escaping. The attack vector leverages the fact that the ls.php script accepts user input through http parameters and concatenates these values directly into sql statements without any sanitization measures. This creates an environment where an attacker can craft malicious input that alters the intended sql query structure, potentially allowing for data extraction, modification, or deletion operations. The vulnerability is particularly dangerous because it affects multiple parameter fields within the same script, expanding the attack surface and providing multiple entry points for exploitation.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete system compromise and potential business disruption. Remote attackers could exploit this vulnerability to gain unauthorized access to sensitive real estate listings, customer data, pricing information, and potentially administrative credentials stored within the database. The implications are severe for real estate platforms where data integrity and confidentiality are paramount, as attackers could manipulate property listings, alter pricing structures, or extract confidential client information. Additionally, the vulnerability could enable attackers to escalate privileges within the system or even execute arbitrary code on the server hosting the landshop application, depending on the underlying database configuration and permissions.
Mitigation strategies for CVE-2005-4018 should prioritize immediate patching of the affected landshop system to version 0.6.4 or later where the sql injection vulnerabilities have been addressed. Organizations should implement proper input validation and sanitization measures, including the use of prepared statements or parameterized queries to prevent direct concatenation of user input into sql commands. The principle of least privilege should be enforced by ensuring database accounts used by the application have minimal required permissions, preventing attackers from executing destructive operations even if successful exploitation occurs. Network segmentation and intrusion detection systems should be deployed to monitor for suspicious sql injection attempts, while regular security audits and penetration testing should be conducted to identify similar vulnerabilities in other components of the system. This vulnerability also aligns with ATT&CK technique T1190 which covers exploitation of remote services, highlighting the need for comprehensive network security controls and proper application security practices.
