Web Ofisi Emlak V2 (SQL Injection) via emlak-ara.html

An attacker exploiting CVE-2019-25459 can inject malicious SQL code into GET parameters such as emlakdurumu, emlaktipi, il, ilce, kelime, and semt. This allows them to bypass authentication and directly interact with the underlying database. Successful exploitation could result in the extraction of sensitive information, including user credentials, property details, and financial data. Depending on database permissions, an attacker might even be able to modify or delete data, leading to significant operational disruption. The lack of authentication requirements amplifies the risk, making the application a prime target for automated scanning and exploitation.

Organizations utilizing Web Ofisi Emlak V2 (2.0.0–V2) for real estate management are at significant risk. This includes small to medium-sized businesses relying on the system for property listings, client management, and financial tracking. Shared hosting environments where multiple users share the same server instance are particularly vulnerable, as a compromise of one user's instance could potentially lead to lateral movement and compromise other users’ data.

• php: Examine web server access logs for requests containing suspicious SQL syntax in GET parameters (e.g., emlak_durumu=1' OR '1'='1). • php: Review the source code of Web Ofisi Emlak, specifically the endpoint handling GET parameters, for unescaped user input used in SQL queries. • generic web: Use curl to test the vulnerable endpoints with various SQL injection payloads:

curl 'http://your-web-ofisi-instance/index.php?emlak_durumu=1' OR '1'='1'

• generic web: Monitor error logs for database-related errors that might indicate a SQL injection attempt.

The primary mitigation for CVE-2019-25459 is to upgrade Web Ofisi Emlak to version 2.5.4 or later. If immediate upgrading is not possible, consider implementing temporary workarounds. Input validation and sanitization on all user-supplied data, particularly GET parameters, is crucial. Web Application Firewalls (WAFs) configured with rules to detect and block SQL injection attempts can provide an additional layer of defense. Review and restrict database user permissions to minimize the impact of a successful attack. After upgrading, verify the fix by attempting a SQL injection attack on the vulnerable endpoints and confirming that the requests are properly sanitized and do not result in database errors.
