CVE-2012-5900 in LandShop
Summary
by MITRE
Multiple SQL injection vulnerabilities in SAMEDIA LandShop 0.9.2 allow remote attackers to execute arbitrary SQL commands via the (1) OB_ID parameter in a single action to admin/action/objects.php, (2) AREA_ID parameter in a single action to admin/action/areas.php, or (3) start parameter in a show action to admin/action/pdf.php.

The CVE-2012-5900 vulnerability represents a critical SQL injection flaw affecting SAMEDIA LandShop version 0.9.2, a content management system designed for real estate listings and property management. This vulnerability resides within the administrative backend components of the application, specifically targeting three distinct parameters across different PHP scripts that handle user input without proper sanitization or validation. The affected files include admin/action/objects.php, admin/action/areas.php, and admin/action/pdf.php, each processing user-supplied data that flows directly into database queries without adequate protection mechanisms. These vulnerabilities fall under the common weakness enumeration CWE-89 which categorizes SQL injection as a fundamental flaw in input validation and database query construction.
The technical exploitation of these vulnerabilities occurs when remote attackers manipulate the OB_ID, AREA_ID, and start parameters to inject malicious SQL code into the application's database queries. When these parameters are processed in the respective PHP scripts, the application fails to implement proper input sanitization or parameterized queries, allowing attackers to construct arbitrary SQL commands that execute with the privileges of the database user. The OB_ID parameter in objects.php likely controls object identification during administrative actions, while AREA_ID in areas.php manages area-related data operations, and the start parameter in pdf.php affects PDF generation functionality. Each of these parameters, when not properly validated, can be leveraged to bypass authentication, extract sensitive data, modify database contents, or even execute operating system commands depending on the database backend configuration and privilege levels.
The operational impact of this vulnerability extends beyond simple data theft or modification, as it provides attackers with potential full administrative control over the affected system. Successful exploitation could result in complete database compromise, allowing unauthorized users to access customer information, property listings, administrative credentials, and potentially other sensitive business data stored within the LandShop application. The vulnerability's remote nature means that attackers do not require physical access to the system, making it particularly dangerous for web applications that are publicly accessible. This type of vulnerability aligns with attack patterns documented in the attack technique T1190 - Proxy Process, where attackers leverage legitimate administrative interfaces to gain unauthorized access and execute malicious commands. The presence of multiple injection points increases the attack surface and provides attackers with alternative exploitation paths, making comprehensive remediation essential.
Mitigation strategies for CVE-2012-5900 must address the fundamental lack of input validation and proper query construction within the affected application components. The primary remediation involves implementing parameterized queries or prepared statements throughout all database interactions, ensuring that user input is properly escaped or sanitized before being incorporated into SQL commands. Additionally, input validation should be enforced at multiple levels including client-side and server-side, with strict type checking and length restrictions applied to all parameters. The application should implement proper access controls and authentication mechanisms to limit administrative access to authorized personnel only, while also ensuring that database accounts used by the application have minimal required privileges. Security patches should be applied immediately to upgrade to a non-vulnerable version of SAMEDIA LandShop, as the vendor has likely released updates addressing these specific vulnerabilities. Regular security testing including automated scanning and manual penetration testing should be conducted to identify similar vulnerabilities in other application components and maintain ongoing security posture. Organizations should also implement database activity monitoring to detect anomalous query patterns that might indicate exploitation attempts.
