The vulnerability identified as CVE-2007-3990 represents a critical SQL injection flaw in the Dora Emlak 1.0 web application, specifically within the default.asp script. This vulnerability manifests when the application processes requests with the goster parameter set to emlakdetay, creating a pathway for remote attackers to manipulate database queries through the id parameter. The flaw stems from inadequate input validation and sanitization practices within the application's query construction logic, allowing malicious users to inject arbitrary SQL commands that execute with the privileges of the database user. The vulnerability is particularly concerning as it enables attackers to bypass authentication mechanisms, extract sensitive data, modify database contents, or potentially escalate privileges within the application's database environment.
This SQL injection vulnerability falls under the CWE-89 category, which specifically addresses SQL injection weaknesses in software applications. The flaw demonstrates poor input handling practices where user-supplied data flows directly into SQL query construction without proper sanitization or parameterization. According to the ATT&CK framework, this vulnerability maps to the T1190 technique for exploitation of remote services, specifically targeting the database layer through web application interfaces. The vulnerability's exploitation requires minimal prerequisites beyond basic network access to the affected web application, making it highly attractive to threat actors seeking persistent database access.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete database compromise and potential system-wide consequences. Attackers can leverage this flaw to perform unauthorized database operations including but not limited to data extraction, modification, or deletion of critical information stored within the Dora Emlak application's database. The vulnerability affects the confidentiality, integrity, and availability of the application's data assets, potentially leading to service disruption and regulatory compliance violations. Given that the vulnerability exists in a real estate management application, the compromised data could include sensitive customer information, property details, and transaction records that would be valuable to cybercriminals.
Mitigation strategies for this vulnerability should prioritize immediate implementation of proper input validation and parameterized queries throughout the application codebase. The most effective remediation involves replacing direct string concatenation of user input with prepared statements or parameterized queries that separate SQL command structure from data values. Additionally, implementing proper input sanitization routines, limiting database user privileges to the minimum required for application operations, and deploying web application firewalls can provide layered defense mechanisms. Regular security code reviews and penetration testing should be conducted to identify similar vulnerabilities in other application components, while maintaining up-to-date security patches for the underlying database management system and web application platform. Organizations should also consider implementing database activity monitoring solutions to detect anomalous SQL query patterns that might indicate exploitation attempts.
