## Overview

A vulnerability exists in BIG-IP and BIG-IQ systems where a highly privileged, authenticated attacker with at least the Resource Administrator role can create SNMP configuration objects through iControl REST or the TMOS shell (tmsh) resulting in privilege escalation.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
