ForgeRock / OpenAM Jato Java Deserialization



This module leverages a pre-authentication remote code execution vulnerability in the OpenAM identity and access management solution. The vulnerability arises from a Java deserialization flaw in OpenAM’s implementation of the Jato framework and can be triggered by a simple one-line GET or POST request to a vulnerable endpoint. Successful exploitation yields code execution on the target system as the service user. This vulnerability also affects the ForgeRock identity platform which is built on top of OpenAM and is thus is susceptible to the same issue.

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/multi/http/cve_2021_35464_forgerock_openam
msf exploit(cve_2021_35464_forgerock_openam) > show targets
msf exploit(cve_2021_35464_forgerock_openam) > set TARGET < target-id >
msf exploit(cve_2021_35464_forgerock_openam) > show options
    ...show and set options...
msf exploit(cve_2021_35464_forgerock_openam) > 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.
