CVE-2021-44529 is a code injection vulnerability in Ivanti Endpoint Manager Cloud Services Appliance (CSA). The flaw allows an unauthenticated attacker to inject and execute arbitrary code on the appliance. Successful exploitation results in code execution under the limited-privilege nobody account rather than full administrative context.

This repository contains a single Metasploit module targeting CVE-2021-44529, a command injection vulnerability in Ivanti Cloud Services Appliance (CSA) prior to version 4.6.0-512. The exploit leverages a flaw in cookie handling on the /client/index.php endpoint, allowing unauthenticated attackers to execute arbitrary commands as the 'nobody' user. The module supports multiple payloads, including Meterpreter reverse shells for Unix, PHP, and Linux platforms, and can use command stagers for binary payload delivery. The exploit is fully weaponized, providing reliable remote code execution with customizable payloads. The code is written in Ruby and is structured as a standard Metasploit module, making it easy to use within the Metasploit framework. The only endpoints referenced are the vulnerable HTTP endpoint and a local file used for version checking.
