Palo Alto Networks warns of claimed critical flaw in PAN-OS management interface
Take action: If by some weird accident, your PAN-OS Management Interface is exposed to the internet, lock it down immediately. Even if you think it's locked down - check again. Because it may become a very serious vector of attack, and the preventative measures are simple - make it accessible only from trusted networks, use encrypted channels (SSH, TLS) and don't even respond to pings.
