Publication date: 2026-02-19

Last updated on: 2026-02-19

Assigner: VulnCheck

Description
RustFly 2.0.0 contains a command injection vulnerability in its remote UI control mechanism that accepts hex-encoded instructions over UDP port 5005 without proper sanitization. Attackers can send crafted hex-encoded payloads containing system commands to execute arbitrary operations on the target system, including reverse shell establishment and command execution.

Executive Summary

RustFly 2.0.0 has a command injection vulnerability in its remote UI control mechanism. This mechanism accepts hex-encoded instructions over UDP port 5005 but does not properly sanitize these inputs.

Because of this lack of sanitization, attackers can send specially crafted hex-encoded payloads containing system commands. These commands can be executed on the target system, allowing attackers to perform arbitrary operations such as establishing a reverse shell or running other commands.

Impact Analysis

This vulnerability can have severe impacts because it allows remote attackers to execute arbitrary system commands without any authentication or user interaction.

  • Attackers can gain unauthorized control over the affected system.
  • They can establish reverse shells, enabling persistent remote access.
  • It can lead to data breaches, system compromise, or disruption of services.
