Juniper Backdoor

[silicon_toad2000]

Networking equipment manufacturer Juniper has confirmed the existence
of the backdoor, which they call unauthorized code, in several of its
products. Outside researchers confirm the backdoor which was designed
to look like debug code. Juniper has released a list of affected
products.

If your Juniper firewall is exposed to the
Internet and unmatched, then it is too late to patch now. Starting
Monday afternoon continuous exploit attempts were detected  for this
vulnerability from multiple sources that appear to scan the internet for
vulnerable systems. The Internet Storm Center went to Infocon
"Yellow" on Monday to alert users of Juniper equipment of the imminent
danger after the backdoor password was revealed by Rapid7.

Juniper Networks, which last month made the startling announcement its NetScreen line of firewalls contained unauthorized code that can surreptitiously decrypt traffic sent through virtual private networks, said it will remove a National Security Agency-developed function widely suspected of also containing a backdoor for eavesdropping.
