|
||
<p>NetworkManager is an universal network configuration daemon for laptops,
|
||
desktops, servers and virtualization hosts.

</p>

|
||
<p>The VPNC plugin provides easy access Cisco Concentrator based VPN’s

<description>
|
||
<p>When initiating a VPNC connection, NetworkManager spawns a new vpnc
|
||
process and passes the configuration via STDIN. By injecting a special
|
||
character into a configuration parameter, an attacker can coerce
|
||
NetworkManager to set the Password helper option to an attacker
|
||
controlled executable file.

<impact type="normal">

<p>A local attacker is able to escalate privileges via a specially crafted
|
||
configuration file.
