CVE-2022-30333PUBLISHED: 2022-05-09RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file. NOTE: WinRAR and Android RAR are unaffected.
CVE-2022-23066PUBLISHED: 2022-05-09
In Solana rBPF versions 0.2.26 and 0.2.27 are affected by Incorrect Calculation which is caused by improper implementation of sdiv instruction. This can lead to the wrong execution path, resulting in huge loss in specific cases. For example, the result of a sdiv instruction may decide whether to tra...

I am not sure if I agree with this reasoning, there is a thing called Zero-Trust especially for environments like hospitals, police stations, utility companies, and IT companies who should have these devices in an isolated environment or VLAN (VXLAN in some cases - VMware Centric). If configured properly, you only allow specific devices to communicate with those devices over a secured connection. I think IPv6 is good to secure devices like this (IoT Devices) because they add an additional layer to the network (IPv6 AES256 IPSec ESP/AH Tunnels). The writer stated that the user should have strong NAC (I agree) with tools to limit the execution of executables on the network so it limits ransomware and external threats and attacks.
This is an example but it gives the reader an idea of the various devices that could exist in any sort of environment. We need to start thinking of Zero-trust designs using locked down methods where baselines of servers and IoT devices are segmented with only a few devices to communicate with servers and/or telecom/network devices.
But think about this, if I can modify the settings on a PLC device, then I can change water temperature, heating/cooling, electrical regulation, so that means those devices need to be isolated because their security posture will not be as high as those in Zone 0 or 1.
So to me, it is not only about the importance of the device, but where the device is located in the IT ecosystem and its function. There needs to be a conversation so if there is any doubt in your mind, then you may need to fortify the design of the network with MFA/2FA, limit who has access to certain devices, if there is a need, put them on a VLAN where VLANs from the admin staff is part of the multi-connect VLAN or VXLAN, and finally, the vendor needs to be consulted to share with them any shortcomings you find (Continuous Diagnostic and Mitigation - CDM).
