Cisco Clean Access Authentication Bypass
------------------------------------------------------------------------
SUMMARY
" <http://www.cisco.com/en/US/products/ps6128/> Cisco Clean Access is an
easily deployed software solution that can automatically detect, isolate,
and clean infected or vulnerable devices that attempt to access your
network."
By Crafting special request, attackers can bypass Cisco Clean Access
Agent's mandatory installation.
DETAILS
Vulnerable Systems:
* Cisco Clean Access Agent version 3.5.4
* Cisco Clean Access Agent version 3.5.3.1
End users can bypass the "mandatory" installation of the Clean Access
Agent by changing the User-Agent string of their browser. This allows them
to connect to the network without the host-based checks being run. If
configured, remote checks are still run.
