The CVE-2010-4738 vulnerability represents a critical SQL injection flaw affecting Rae Media INC's Real Estate Single and Multi Agent System version 3.0. This vulnerability exists in two distinct attack vectors within the application's web interface, specifically targeting the multi/city.asp file in the Multi Agent System and the resulttype.asp file in the Single Agent System. The flaw arises from insufficient input validation and sanitization of user-supplied data, particularly the probe parameter that is processed without proper security controls. This vulnerability falls under the CWE-89 category of SQL Injection, which is classified as a serious weakness in application security that allows attackers to manipulate database queries through malicious input.
The technical implementation of this vulnerability allows remote attackers to execute arbitrary SQL commands by manipulating the probe parameter in the specified files. When the application processes the probe parameter, it directly incorporates user input into SQL query construction without proper parameterization or input sanitization. This creates an environment where attackers can inject malicious SQL code that gets executed by the database server. The attack can be leveraged to extract sensitive data from the database, modify or delete records, and potentially gain unauthorized access to the underlying database system. The vulnerability affects both the Multi Agent System and Single Agent System components, indicating a systemic security flaw in the application's data handling architecture.
The operational impact of this vulnerability is severe for real estate systems that handle sensitive customer information, property listings, and transaction data. Attackers could exploit this flaw to access confidential real estate listings, customer contact information, transaction records, and potentially financial data. The remote nature of the attack means that threat actors do not require physical access to the system or network to exploit the vulnerability. This creates a significant risk for real estate agencies and brokers who rely on these systems for business operations, as successful exploitation could lead to data breaches, regulatory violations, and reputational damage. The vulnerability also enables privilege escalation attacks that could allow attackers to gain administrative access to the application and database.
Mitigation strategies for CVE-2010-4738 should focus on implementing proper input validation and parameterized queries to prevent SQL injection attacks. Organizations should immediately apply the vendor's security patches if available or implement application-level protections such as input sanitization, output encoding, and proper error handling. The implementation of web application firewalls and database access controls can provide additional layers of protection. Security teams should also conduct comprehensive code reviews to identify and remediate similar vulnerabilities throughout the application codebase. According to ATT&CK framework, this vulnerability maps to T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS), as attackers would typically use these techniques to probe and exploit the vulnerable web application. Organizations should also consider implementing database activity monitoring and intrusion detection systems to detect and respond to potential exploitation attempts. The vulnerability highlights the importance of following secure coding practices and conducting regular security assessments to identify and remediate application-level weaknesses before they can be exploited by malicious actors.
