If attackers acquire the encryption file, they may crack the DES encryption algorithm to get the password.
The vulnerability classification has been performed by using the CVSSv2 scoring system (http://www.first.org/cvss/).
Base Score: 6.5 (AV:N/AC:L/Au:S/C:P/I:P/A:P)
Temporal Score: 5.6(E:F/RL:T/RC:C)
Prerequisite:
The attacker can log in to the device, and has privilege to get configuration with encrypted passwords.
Procedures:
The attacker acquires the user password stored by encryption and crack DES encryption algorithm to get the password in clear text.
Impact:
The attacker acquires the password.1. Enhance the remote login management to the equipment and only allow login within the operator’s management network.
2. Strictly manage the accounts privilege.
3. Change the password regularly.
1.Abandon DES algorithm and adopt AES256 algorithm.
