| Titolo | TRENDnet TEW-WLC100 TEW-WLC100 2.05b02 Misconfiguration |
|---|
| Descrizione | **Description:** In the configuration file of `racoon` in the TRENDnet TEW-WLC100 2.05b02, the first item of `exchage_mode` property is set to aggressive. Aggressive mode in IKE Phase 1 exposes identity information in plaintext, is vulnerable to offline dictionary attacks, and lacks flexibility in negotiating security parameters.
**Detail:**
In the `TEW-WLC100 2.05b02` firmware, the partial content of `/etc/racoon.conf` is as follows.
```
remote ::1 [8000]
{
#exchange_mode main,aggressive;
exchange_mode aggressive,main;
doi ipsec_doi;
situation identity_only;
my_identifier user_fqdn "[email protected]";
peers_identifier user_fqdn "[email protected]";
#certificate_type x509 "mycert" "mypriv";
nonce_size 16;
lifetime time 1 min; # sec,min,hour
proposal {
encryption_algorithm 3des;
hash_algorithm sha1;
authentication_method pre_shared_key;
dh_group 2;
}
}
```
The official documentation of racoon (https://manpages.ubuntu.com/manpages/trusty/man5/racoon.conf.5.html) states the following requirements.
```
SECURITY CONSIDERATIONS
The use of IKE phase 1 aggressive mode is not recommended, as described in
<http://www.kb.cert.org/vuls/id/886601>.
```
Clearly, there is a misconfiguration vulnerability here. Aggressive mode in IKE Phase 1 exposes identity information in plaintext, is vulnerable to offline dictionary attacks, and lacks flexibility in negotiating security parameters. |
