Description

This module exploits a command injection vulnerability in the Ivanti Cloud Services Appliance (CSA) for Ivanti Endpoint Manager. A cookie based code injection vulnerability in the Cloud Services Appliance before `4.6.0-512` allows an unauthenticated user to execute arbitrary code with limited permissions. Successful exploitation results in command execution as the `nobody` user.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/linux/http/ivanti_csa_unauth_rce_cve_2021_44529
msf exploit(ivanti_csa_unauth_rce_cve_2021_44529) > show targets
    ...targets...
msf exploit(ivanti_csa_unauth_rce_cve_2021_44529) > set TARGET < target-id >
msf exploit(ivanti_csa_unauth_rce_cve_2021_44529) > show options
    ...show and set options...
msf exploit(ivanti_csa_unauth_rce_cve_2021_44529) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
