Web Ofisi Emlak v2 SQL Injection via ara Parameter

The SQL Injection vulnerability in Web Ofisi Emlak presents a significant risk. An attacker can leverage this flaw to bypass authentication and directly manipulate database queries. This could result in the extraction of sensitive data, including user credentials, financial information, or other confidential records stored within the database. Furthermore, the attacker could execute arbitrary SQL commands, potentially leading to data corruption, modification, or complete deletion. The impact extends beyond data theft; a successful attack could render the application unusable, causing a denial-of-service condition. While no specific real-world exploitation has been publicly reported, the ease of exploitation and the potential for severe consequences make this a high-priority vulnerability.

Organizations utilizing Web Ofisi Emlak v2.0.0–v2, particularly those hosting the application on shared hosting environments or without robust input validation practices, are at significant risk. Legacy deployments that have not been regularly updated are also particularly vulnerable.

• php: Examine web server access logs for requests to URLs containing the 'ara' parameter with unusual characters or SQL keywords (e.g., 'UNION', 'SELECT', ';').

grep 'ara[=].*UNION.*' /var/log/apache2/access.log

• php: Search application code for instances where the 'ara' parameter is used in SQL queries without proper sanitization or escaping. • generic web: Use a WAF to monitor and block requests containing SQL injection payloads targeting the 'ara' parameter. • generic web: Monitor database logs for unusual SQL queries originating from the application server.

The primary mitigation for CVE-2019-25456 is to upgrade Web Ofisi Emlak to version 2.5.4 or later, which includes the necessary fix. If immediate upgrading is not possible, consider implementing temporary workarounds. Input validation and sanitization on the 'ara' parameter are crucial. Employing a Web Application Firewall (WAF) with SQL Injection protection rules can help block malicious requests. Regularly review database access logs for suspicious activity, specifically looking for unusual SQL queries originating from the 'ara' parameter. Consider implementing stricter database user permissions to limit the impact of a successful SQL Injection attack.
