Splunk edit_user Capability Privilege Escalation
Posted on 27 October 2023
Splunk suffers from an issue where 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 remote code execution.
