Loading vulnerability…
VMware View Planner 4.x before 4.6 Security Patch 1 contains an arbitrary file-upload vulnerability in the logupload web application. Improper input validation combined with missing authorization controls permits an unauthenticated network attacker to upload a specially crafted file to the View Planner Harness and execute it within the logupload container, resulting in remote code execution.

This repository contains a single Metasploit module targeting VMware View Planner 4.6 (prior to Security Patch 1) for an unauthenticated remote code execution vulnerability (CVE-2021-21978). The exploit abuses an arbitrary file upload flaw in the log_upload_wsgi.py component, allowing an attacker to upload a backdoored Python file. The module then triggers the backdoor via an HTTP OPTIONS request, resulting in code execution as the 'apache' user inside the appacheServer Docker container. The exploit is weaponized, supporting customizable Python payloads (defaulting to a Meterpreter reverse shell). The main endpoints targeted are '/wsgi_log_upload/log_upload_wsgi.py' (for vulnerability checking) and '/logupload' (for file upload and execution). The code is written in Ruby and is structured as a standard Metasploit exploit module, with clear separation of checking, exploitation, and cleanup (restoring the original file after exploitation).
