Splunk "edit_user" Capability Privilege Escalation

Disclosed

Description

A low-privileged user who holds a role that has the "edit_user" capability assigned to it can escalate their privileges to that of the admin user by providing a specially crafted web request. This is because the "edit_user" capability does not honor the "grantableRoles" setting in the authorize.conf configuration file, which prevents this scenario from happening. This exploit abuses this vulnerability to change the admin password and login with it to upload a malicious app achieving RCE.

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.
