A vulnerability has been found in SonicWALL Tele2 and SOHO 6.0.0.0 (Firewall Software) and classified as critical. This vulnerability affects an unknown functionality of the component IPsec Handler. The manipulation with an unknown input leads to a missing encryption vulnerability. The CWE definition for the vulnerability is CWE-311. The product does not encrypt sensitive or critical information before storage or transmission. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

SonicWALL Tele2 and SOHO firewalls with 6.0.0.0 firmware using IPSEC with IKE pre-shared keys do not allow for the use of full 128 byte IKE pre-shared keys, which is the intended design of the IKE pre-shared key, and only support 48 byte keys. This allows a remote attacker to brute force attack the pre-shared keys with significantly less resources than if the full 128 byte IKE pre-shared keys were used.
