When BIG-IP DNS is provisioned, a vulnerability exists in an undisclosed iControl REST and BIG-IP TMOS Shell (tmsh) command that may allow an authenticated attacker with the Resource Administrator or Administrator role to execute arbitrary system commands with higher privileges. In Appliance mode deployments, a successful exploit can allow the attacker to cross a security boundary.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
