SSH Weak MAC Algorithms Enabled Go to solution mike kao Level 1 11-29-2016 10:32 AM - edited 03-10-2019 12:45 AM Hi , My 2960X is accused of weaknesses by Nessus. http://static.tenable.com/documentation/reports/html/PCI_Scan_Plugin_w_Remediations.html#idp35720560 I can ...
Before the cause of the SSH issues are explained, it is necessary to know about the 'SSH Server CBC Mode Ciphers Enabled & SSH Weak MAC Algorithms Enabled' vulnerability which affects the Nexus 9000 platform. CVE ID - CVE- 2008-5161 (SSH Server CBC Mode Ciphers Enabled...
Can someone help to know how we can change SSH KEX values on IOS devices as per recommended option to close this weaker SSH KEX algorithm enabled or any info that states current values are not come into weak algorithm. inXXXX #sh ip ssh | i KEXKEX Algorithms:diffie-h...
In addition to SSHweak MAC algorithms, weak SSH key exchange algorithms are common findings on pentest reports. The SSH key exchange algorithm is fundamental to keep the protocol secure. It is what allows two previously unknown parties to generate a shared key in plain sight, and have that se...

Solved: Hi Guys, In customer VA/PT it is been found that ISE 2.3P4 is using weak cipher (aes-128-cbc & aes-256-cbc) for SSH and now Cisco is asked back to disable these cipher and enable aes-128-ctr and aes-256-ctr. We tested in lab environment, it
Solved: Hello, Our client ordered PenTest, and as a feedback they got recommendation to "Disable SSH CBC Mode Ciphers, and allow only CTR ciphers" and "Disable weak SSH MD5 and 96-bit MAC algorithms" on their Cisco 4506-E
