Splunk Enterprise deployment servers allow client publishing of forwarder bundles

Vulnerability Description

Splunk Enterprise deployment servers in versions before 8.1.10.1, 8.2.6.1, and 9.0 let clients deploy forwarder bundles to other deployment clients through the deployment server. An attacker that compromised a Universal Forwarder endpoint could use the vulnerability to execute arbitrary code on all other Universal Forwarder endpoints subscribed to the deployment server.
