CVE-2019-25462

CVE-2019-25462

Analysis

The vulnerability is an SQL injection flaw in Web Ofisi Rent a Car v3, a vehicle rental management system. The application fails to sanitize user input passed through the 'klima' GET parameter on the car listing page (arac-listesi.html). An attacker can inject arbitrary SQL code directly into the database query, as demonstrated in publicly available exploit proofs of concept [2].

Exploitation

Exploitation requires no authentication; the vulnerable endpoint is accessible to any unauthenticated user who can send HTTP GET requests to the web application. The PoC from Exploit-DB shows that the 'klima' parameter (as well as other parameters like kategori[] and vites[]) can be used to inject SQL payloads. A simple payload such as 1 AND 3*2*1=6 AND 695=695 confirms the injection point. The attack can be performed remotely over the network, with no special privileges needed [2].

Impact

A successful SQL injection allows an attacker to read, modify, or delete arbitrary data in the application's database. This can lead to extraction of sensitive information (e.g., user credentials, customer records). The description also notes that denial-of-service conditions are possible through crafted queries [1][2]. Since the demo site provides admin panel credentials (demo/demo), a real-world attacker could also potentially escalate from SQL injection to full administrative control of the rental system.

Mitigation

As of the publication date, the vendor has not released a patched version. The software page lists no security fixes. Given the age of the CVE (assigned retroactively in 2026 for a 2019 issue) and the presence of a public exploit, administrators should upgrade to a newer, secure version or implement web application firewall (WAF) rules to block SQL injection patterns. Until official remediation is available, disabling the affected functionality or applying input validation is advised [1][2].
