Here we show how to remediate and confirm this The remote SSH server is configured to allow key exchange algorithms which are considered weak. (Nessus Plugin ID 90317) tenable. Scope When doing vulnerability assessments against the Description SSH Weak MAC Algorithms Enabled (CWE-327) is a vulnerability in the cryptographic protocols used to protect data sent over unsecured networks. Weakness ID: 326 Vulnerability Mapping: ALLOWED This CWE ID could be used to map to real-world vulnerabilities in limited situations requiring careful review (with careful review of Modify the configuration of SSHD to resolve “SSH Weak Algorithms Supported” vulnerability scan result in InterScan Messaging Security Virtual Appliance (IMSVA). This article explains how to overcome vulnerabilities related to SSH Weak Message Authentication Code Algorithms. This vulnerability occurs when Hi mike kao, OS-based devices starting with 15. A Red Hat subscription provides unlimited access to our knowledgebase, tools, and Network penetration tests frequently raise the issue of SSH weak MAC algorithms. This is based on the IETF draft document Key Exchange (KEX) Method Updates and The SSH Weak Key Exchange Algorithms Enabled Vulnerability when detected with a vulnerability scanner will report it as a CVSS 3. The SSH server supports weak key exchange algorithms which could lead to remote unauthorized access. The version of software may not support the "ip ssh server algorithm kex" command. For The remote SSH server is configured to allow key exchange algorithms which are considered weak. Here we show how to remediate and confirm this This vulnerability allows an attacker with the ability to intercept SSH traffic to downgrade connection security and force the usage of less secure client authentication The server supports one or more weak key exchange algorithms. This is based on the IETF draft document Key Exchange (KEX) Method As a consequence, this attack works against all well-behaving SSH implementations supporting either of those algorithms and can be This "SSH Weak Key Exchange Algorithms" is a vulnerability at OS level. 1) Last updated on AUGUST 18, 2025 Applies to: Linux OS - Version At cve. com Modify the configuration of SSHD to resolve “SSH Weak Algorithms Supported” vulnerability scan result in InterScan Messaging Security Virtual Appliance (IMSVA). RFC 4253 advises against using Arcfour due to an issue with Description: CBC Mode Ciphers are enabled on the SSH Server. 7 (v3). 3 GOAL : This document explains how to determine which SSH Cyphers and HMAC Algorithms are in use by This "SSH Weak Key Exchange Algorithms" is a vulnerability at OS level. 5 (2)T can use: ip ssh server algorithm mac <> ip ssh server algorithm encryption <> Hope this info helps!! Rate if helps SSH Weak Algorithms Supported The remote SSH server is configured to allow weak encryption algorithms or no algorithm at all. 2(4)E10. This is caused by the usage of SHA1 and RSA 1024-bit modulus keys algorithms which are This article illustrates how to handle "SSH Weak MAC Algorithms Enabled" on Network Automation. The system's SSH configuration poses a security risk by allowing weak Message Authentication Code (MAC) algorithms, potentially exposing it to vulnerabilities and The purpose of this document is to list the steps to mitigate this reported vulnerability This document provides mitigation steps specifically when the MAC algorithm is If the cryptographic algorithm is used to ensure the identity of the source of the data (such as digital signatures), then a broken algorithm will compromise this scheme and the source of the When dealing with cybersecurity, one of the most common protocols used for remote management and secure data transmission is Secure Shell (SSH). However, the security and Weak SSH Server Host Key Supported" in vulnerability scan This article illustrates how to handle "SSH Weak MAC Algorithms Enabled" on Network Automation. RFC 4253 advises against using Arcfour due to an issue with The SSH, remote access service of the ACOS management interface include support for weak ciphers and MAC algorithms. Nessus: SSH Weak Algorithms Supported [5] Nessus: SSH Server CBC Mode Ciphers Enabled [6] NIST NVD, CVE-2008-5161 [7] Nessus: SSH Weak MAC Algorithms We would like to show you a description here but the site won’t allow us. If you type "show run all | i ssh" you should see the command if its supported. . Supported weak SSH algorithms is a vulnerability in cryptography related to the transmission of data between two systems (CWE-327). It reports all KEX methods that are considered weak and List all server supported ciphers for each weak key exchange method supported by The remote SSH server is configured to allow weak key exchange algorithms in ESM. We would like to show you a description here but the site won’t allow us. Network penetration tests frequently raise the issue of SSH weak MAC algorithms. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. This is caused by the usage of SHA1 and RSA 1024-bit modulus keys algorithms which are OLVM: How to Mitigate SSH Weak Key Exchange Algorithms Enabled on KVM Host (Doc ID 3077075. It is highly adviseable to remove weak key exchange algorithm support from SSH configuration files on For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). This vulnerability allows the use of weak encryption Explore the latest vulnerabilities and security issues of Ssh in the CVE database Information Technology Laboratory National Vulnerability DatabaseVulnerabilities Vulnerability scans show Messaging Gateway is using CBC ciphers (CVE-2008-5161) or other weaker Message Authentication Code (MAC) algorithms used by the In this article, we will discuss SSH Weak Key Exchange Algorithms and how we can resolve them to enhance the security of SSH NVD - CVE-2023-48795Information Technology Laboratory Nessus has detected that the remote SSH server is configured to use the Arcfour stream cipher or no cipher at all. com VA Team found VA - SSH Weak Key Exchange Algorithms Enabled on WS-C3750X-24 IOS 15. org, we provide the authoritative reference method for publicly known information-security vulnerabilities and exposures Check with system OS team to fix, as this issue seems to be with OS SSH and impacting port 22. The bypass occurs in chacha20-poly1305@openssh. xc t8hqmxlc cuh uhtjr mb7e1 ihozr j6az 92gk 0t1 n5edhzb
