The vulnerability identified as CVE-2008-2190 represents a critical SQL injection flaw within the Online Rent rental property management system version 4.5 and earlier, with subsequent confirmation that version 5.0 and earlier remain susceptible to the same issue. This vulnerability exists in the index.php script which processes user input through the pid parameter, creating an exploitable pathway for malicious actors to manipulate database queries. The flaw stems from inadequate input validation and sanitization mechanisms that fail to properly escape or filter user-supplied data before incorporating it into SQL command structures.
The technical implementation of this vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses where untrusted data is directly concatenated into SQL queries without proper escaping or parameterization. Attackers can exploit this by crafting malicious payloads in the pid parameter that alter the intended SQL query structure, potentially allowing them to execute unauthorized database operations. The impact extends beyond simple data theft to include complete database compromise, privilege escalation, and potential system infiltration. This vulnerability operates at the application layer and can be classified under the ATT&CK technique T1071.004 for application layer protocol manipulation, specifically targeting web application interfaces.
The operational consequences of this vulnerability are severe for any organization utilizing the affected software, as it provides attackers with direct access to backend databases containing sensitive rental property information, customer data, and transaction records. Remote exploitation requires no authentication and can be executed through standard web browser interfaces, making it particularly dangerous for publicly accessible rental management systems. The vulnerability enables attackers to perform unauthorized read, write, and delete operations on database tables, potentially leading to complete system compromise and data exfiltration. Organizations running these versions face significant risk of regulatory violations, financial losses, and reputational damage from data breaches.
Mitigation strategies for CVE-2008-2190 require immediate implementation of proper input validation and parameterized queries to prevent SQL injection attacks. Organizations should upgrade to versions 5.1 and later of the Online Rent system where patches have been implemented to address the vulnerability. Additional protective measures include implementing web application firewalls, conducting regular security code reviews, and establishing proper database access controls. The remediation process must involve thorough input sanitization, use of prepared statements, and comprehensive testing of all user-supplied parameters to ensure that malicious input cannot influence SQL query execution. Security teams should also implement monitoring systems to detect anomalous database access patterns that may indicate exploitation attempts.
