2. 漏洞复测系列 -- SSH 支持弱加密算法漏洞(SSH Weak Algorithms Supported),程序员大本营,技术文章内容聚合第一站。
SSH Weak Encryption Algorithms Supported SSH使用了弱加密算法,解决方法: 在/etc/ssh/sshd_config中显式指定ssh通讯时使用的加密算法 在文件的最后加上: Ciphers aes128-ctr,aes192-ctr,aes256-ctr 然后重启sshd: service sshd restart
弱加密算法漏洞修复 SSH Weak Encryption Algorithms Supporte SSH配置文件中加密算法没有指定,默认支持所有加密算法,包括arcfour,arcfour128,arcfour256等弱加密算法。但是目前RC4是不安全算法 若数据库安全性要求比较高,这个漏洞还是必须要修复的,下面记录下Oracle RAC修复过程,此修复过程不影响现有系统。 如有不当欢迎斧...
The following are the most common weak MAC algorithms encountered: hmac-md5 hmac-md5-96 hmac-sha1-96 hmac-sha2-256-96 hmac-sha2-512-96 Pentesting SSH MAC Algorithms Pentesters can quickly confirm what SSH MAC algorithms are supported with the followingnmap script: ...

The remote SSH server is configured to allow key exchange algorithms which are considered weak. This is based on the IETF draft document Key Exchange (KEX) Method Updates and Recommendations for Secure Shell (SSH)draft-ietf-curdle-ssh-kex-sha2-20. Section 4 lists guidance on...
Then you need to recycle ssh: service sshd restart Then you can confirm with the local command: sshd -T | grep -i kex and it will list what our SSHD accepts. Also you can confirm this with the following nmap command: nmap -sV -p 22 --script ssh2-enum-algos <servername>...
