|
<p>
|
|
<i>racoon</i> (a utility in the ipsec-tools package) does not verify digital
|
|
signatures on Phase1 packets. This means that anybody holding the correct
|
|
X.509 certificate would be able to establish a connection, even if they did
|
|
not have the corresponding private key.
|
|
</p>

|
<impact type="high">
|
|
<p>
|
|
Since digital signatures are not verified by the <i>racoon</i> tool, an attacker may
|
|
be able to connect to the VPN gateway and/or execute a man-in-the-middle attack.
