Successful exploit could allow an attacker to decrypt ciphertext data, causing information leaks.
The vulnerability classification has been performed by using the CVSSv2 scoring system (http://www.first.org/cvss/).
Base Score: 4.3 (AV:N/AC:M/Au:N/C:P/I:N/A:N)
Temporal Score: 3.6 (E:F/RL:O/RC:C)
1. Prerequisite:
The attacker has access to the network of the affected devices.
2. Attacking procedure:
The servers provide an option for users to select SSH encryption algorithms. If a user selects an insecure encryption algorithm, an attacker can decrypt ciphertext data, causing information leaks.
