Executive Summary

This vulnerability is a Cross-Site Request Forgery (CSRF) issue found in the RustDesk Client (rustdesk-client) on multiple platforms including Windows, MacOS, Linux, iOS, and Android. It involves the Flutter URI scheme handler and FFI bridge modules, specifically in program files such as flutter/lib/common.Dart, src/flutter_ffi.Rs, and the URI handler for rustdesk://password/. The vulnerability allows an attacker to perform privilege escalation by exploiting the bind.MainSetPermanentPassword() routine.

Impact Analysis

This vulnerability can lead to privilege escalation, meaning an attacker could gain higher-level access or control over the RustDesk Client than intended. This could allow unauthorized actions or changes within the application, potentially compromising the security and integrity of the system where the client is installed.
