Ssh weak algorithms supported arcfour. SSH is configured in /etc/ssh/sshd_config. Note that Nessus has detected that the remote SSH server is configured to use the Arcfour stream cipher or no cipher at all. So you may have to explicitly set a more restrictive value for Ciphers. Hi, While scanning Dynatrace ActiveGate for VAPT vulnerabilities "SSH Weak Algorithms Supported" this point is highlighted by concern team. Depending on your system, you need to add all the other algorithms to the option Ciphers in that file. I know that arcfour is fast for file transfers This document specifies methods of using the Arcfour cipher in the Secure Shell (SSH) protocol that mitigate the weakness of the cipher's key-scheduling algorithm. SSH's configuration file is not specified, and all encryption algorithms are supported by default, including ArcFour, ArcFour128, ArcFour256 and other weak encryption algorithms. Note the presence of the arcfour ciphers. RFC 4253 advises against using Arcfour due to an The effect is that nessus detected the Arcfour encryption algorithm or no encryption algorithm in the SSH service configuration. Nessus has detected that the remote SSH server is configured to use the Arcfour stream cipher or no cipher at all. RFC 4253 advises against using Arcfour due to an issue SSH Weak Algorithms Supported: Tester has detected that the remote SSH server is configured to use the Arcfour stream. 3. It has been detected that the remote SSH server is configured to use the Arcfour stream cipher or no cipher . The Nessus security scan is detected that the remote SSH server is configured to use the Arcfour stream cipher or no cipher at all. The SSH service has enabled Arcfour (also known as This document specifies methods of using the Arcfour cipher in the Secure Shell (SSH) protocol that mitigate the weakness of the cipher's key-scheduling algorithm. Vulnerability Description: Nessus has detected that the Hi Team, Our client ordered penetration test, and as a feedback they got recommendation on the Cisco UCS BE6K server "The remote SSH server is configured to allow weak encryption algorithms or no The remote SSH server is configured to allow weak encryption algorithms or no algorithm at all. [STANDARDS-TRACK] The following weak server-to-client encryption algorithms are supported : arcfour; arcfour128; arcfour256;The following weak client-to-server encryption algorithms are supported : arcfour; What are the differences between the arcfour, arcfour128 and arcfour256 ciphers in OpenSSH? I am interested about: speed and security implications. RFC 4253 advises against using Arcfour due to an issue with Vulnerability Description: Nessus has detected that the remote SSH server is configured to use the Arcfour stream cipher or no cipher at all. ssh -Q cipher from the client will tell you which schemes your client can support. Brief analysis of loopholes According to the description given by nessus, it can be seen that this vulnerability is a configuration defect of SSH. [STANDARDS-TRACK] Nessus has detected that the remote SSH server is configured to use the Arcfour stream cipher or no cipher at all. RFC 4253 advises against using Arcfour due to an issue with weak keys.
