high Nessus Plugin ID 147346

Language:

Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has cloud-init packages installed that are affected by a vulnerability:

 - The default cloud-init configuration, in cloud-init 0.6.2 and newer, included ssh_deletekeys: 0, disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances created by cloning a golden master or template system, sharing ssh host keys, and being able to impersonate one another or conduct man-in-the-middle attacks. (CVE-2018-10896)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL cloud-init packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
