No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A vulnerability exists in an undisclosed BIG-IP TMOS Shell (tmsh) command that may allow an authenticated attacker with 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.
