Loading vulnerability…
CVE-2021-22652 is a critical vulnerability in Advantech iView versions prior to v5.7.03.6112, where missing authentication on configuration endpoints allows an unauthenticated attacker to modify configuration settings and achieve remote code execution. The flaw exists due to the absence of access controls on sensitive configuration functions, enabling arbitrary command execution without prior authentication.

This repository contains a single Metasploit module (advantech_iview_unauth_rce.rb) that exploits an unauthenticated remote code execution vulnerability (CVE-2021-22652) in Advantech iView versions up to 5.7.02.5992. The exploit leverages two unauthenticated primitives: configuration change and arbitrary file write, to deploy a malicious JSP webshell to the server's web directory. The module then executes arbitrary commands or payloads (such as Meterpreter or PowerShell stagers) as the user running iView, typically with SYSTEM privileges. The exploit is fully weaponized, supporting multiple payload types and architectures, and is highly reliable. The main attack vector is network-based, targeting the HTTP(S) interface of the iView application, specifically the /iView3/ path and its servlets. The module is structured with clear separation of configuration retrieval, update, file write, and command execution logic, and includes cleanup routines to restore the original configuration. The only file in the repository is the Metasploit exploit module itself, written in Ruby.
