CVE-2021-22006 is a reverse proxy bypass vulnerability in VMware vCenter Server. The vulnerability arises from improper handling of URIs by the vCenter Server's reverse proxy endpoints. An attacker with network access to port 443 on the vCenter Server can exploit this flaw to bypass access controls and reach restricted endpoints that should not be directly accessible.

This repository contains a Python proof-of-concept exploit for CVE-2021-22005, a critical file upload vulnerability in VMware vCenter Server. The exploit abuses a path traversal flaw in the analytics API to upload a malicious JSP web shell to the server. The main script, 'CVE-2021-22005_PoC.py', generates random names for the agent, shell, and password, then crafts and sends HTTP requests to the vulnerable endpoints to create an agent and upload a manifest that results in the web shell being written to disk. Once the shell is in place, the script provides an interactive pseudo shell, allowing the attacker to execute arbitrary commands on the target server via the uploaded JSP shell. The README provides usage instructions and context for the exploit. The exploit targets VMware vCenter Server instances that are unpatched for CVE-2021-22005 and accessible over the network.
