A recent vulnerability, dubbed CVE-2022-3797, has been discovered in the eoLinker API-to-Dashboard, an API management tool. It has been rated as problematic, and the potential repercussions of this vulnerability must be addressed. In this post, we will delve into the details of the issue, including how it can be exploited, and provide some guidance on potential mitigations.

Exploit Details

This particular vulnerability impacts the unknown processing of the file /login, and the manipulation of the callback argument can lead to an open redirect. Essentially, this means that an attacker can initiate the exploitation remotely, potentially leading users to malicious websites as a result.

The vulnerability has been assigned the identifier VDB-212633 and is now publicly disclosed. As a consequence, attackers might actively exploit this issue, putting systems at risk.

The following code snippet is an example of how the callback argument may be manipulated

import requests

target_url = "http://target.example.com/login";
payload = "?callback=http://malicious.example.com";

exploit_url = target_url + payload
response = requests.get(exploit_url)

if response.status_code == 200:
    print("Exploit successful")
    print("Exploit failed")

In this example, the attacker aims to redirect users from the target website to a malicious one by manipulating the callback argument in the URL.
