Cryptography / SSH Server CBC Mode Ciphers Enabled

Description

SSH Server CBC Mode Ciphers Enabled is a vulnerability that affects security in the domain of Cryptography. The vulnerability may allow an attacker to recover the plaintext from the ciphertext. It can be detected through various means, such as the use of automated vulnerability assessment tools, manual source code review, or by inspecting the configurations of the SSH server.

Risk

The risk that this vulnerability can pose is high due to its ability to provide attackers with unauthorized access to the server. This can potentially lead to the attacker gaining access to confidential information, as well as gaining control over the server itself. The consequences of an attack depending on the severity of the exploitation can range from a minor data leak to a full-scale breach of the server.

Solution

The best solution to remediate this vulnerability is to disable CBC Mode Ciphers from the SSH server. Additionally, it is recommended to use the newer and more secure modes such as CTR and GCM.
