Root privilege escalation via streamfwd

Privilege escalation in Splunk App for Stream before 8.1.1 allows local users to gain root access through the streamfwd process. Splunk identifies streamfwd as the affected component but has not disclosed the faulty operation or the untrusted input that triggers it. Exploitation requires an existing low-privileged account on a machine running the app, and successful exploitation grants control up to the root user.
