Impact
1．If attackers acquire the encryption file, they may crack the DES encryption algorithm
to get the password.
Vulnerability Scoring Details
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)
Technique Details
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.
Temporary Fix
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.
Software Versions and Fixes
Solutions:
Abandon DES algorithm and adopt AES256 algorithm.
