CVE-2024-45388 Scanner

Hoverfly is a lightweight service virtualization and API simulation tool used by developers and testers to mimic real-world API interactions. It is designed for easy integration into CI/CD pipelines and automating API tests. The tool provides powerful features for recording and simulating HTTP traffic, making it ideal for complex API scenarios. Hoverfly is often used in environments where accurate API behavior simulation is critical to testing. It is widely used by organizations for ensuring reliable API functionality during software development and testing.

The Arbitrary File Read vulnerability in Hoverfly allows an attacker to access files on the server without proper authorization. Exploiting this issue requires sending specially crafted HTTP requests to the vulnerable Hoverfly instance. The vulnerability arises from improper handling of file paths in simulation requests, enabling attackers to read sensitive files. This flaw can lead to exposure of critical server information.

The vulnerability exists in the /api/v2/simulation POST handler of Hoverfly, which processes simulation creation requests. An attacker can manipulate the bodyFile parameter to specify arbitrary file paths on the server. By using directory traversal techniques, attackers can access sensitive files such as /etc/passwd. The response from the server reveals the contents of these files, allowing the attacker to read them without authentication. This issue affects Hoverfly versions below 1.10.3.

Exploitation of this vulnerability can lead to unauthorized disclosure of sensitive server files. Attackers could gain access to system configuration files, potentially leading to further system compromise. If critical information such as password files is exposed, it could be used to elevate privileges or execute further attacks against the server. Additionally, exposure of configuration files might reveal network or application credentials, resulting in wider security breaches.
