Overview
CVE-2023-49261 is a severe vulnerability that exposes the “tokenKey” value used in user authorization in the HTML source of the login page. This exposure puts systems and their data at high risk as it could potentially lead to system compromise or data leakage. This vulnerability can affect any online platform or system that uses the exposed “tokenKey” value for user authorization.

How the Exploit Works
The exploit works by taking advantage of the “tokenKey” value exposure in the HTML source code of the login page. An attacker can view the HTML source code, find the exposed “tokenKey” value, and use it to bypass the user authorization process. This could allow the attacker to gain unauthorized access to the system and its data.
Conceptual Example Code
Given the nature of the vulnerability, an attacker might exploit it using an HTTP request like the following:
GET /login.html HTTP/1.1
Host: target.example.com
<!-- The attacker then locates the "tokenKey" value in the HTML source code of the login page -->
POST /auth/login HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "tokenKey": "exposed_token_key_value" }Please note that this is a conceptual example and the actual exploit could vary depending on the specific implementation of the affected system.
