See SSH Prefix Truncation Vulnerability Used in Terrapin Attacks (CVE-2023-48795)
The iDRAC for the Dell r640xl and the ME4 storage arrays attached are vulnerable.
Security Analytics 8.2.7
For the iDRAC, login to the idrac and searched for the keyword ssh in the top right corner. This navigates directly to the Services -> SSH menu to Enable or Disable ssh.
For the ME4 storage login and select Home -> Action -> System Settings -> Services and deselect SSH.
For sites that require ssh access to the iDRAC and ME4 Web UI, the vulnerable cypher can be removed. Dell has provided the instructions. Broadcom has not tested and does not support this configuration change.
