@neiltiffin See this is precisely the issue, it's important to actually read into the vulnerabilities before just saying CVSS 9.8 it's the end of the world.
If you knew what the actual issue was, it's basically a non issue. No one should be exposing their firewall webGUI to the public internet anyway, or any untrusted network for that matter, it should be accessed over a VPN. The whole purpose of that general best practice advise is to avoid issues like this being a problem (which BTW basically every other firewall has had similar login related CVEs that were super bad, many worse than just brute force allowance) when they do pop up. While it's important for things like this to be fixed (and it is fixed) regardless, admins still need to practice best security advise.
Additionally, all this vuln lets you do is brute force without any restrictions, but if you're following another best practice and using good strong login credentials, it shouldn't matter anyway.
I also don't understand this: "at least one major vulnerability that went un-resolved in pfsense 2.6", so what you are saying is that something got fixed but since it wasn't fixed in the version you wanted it to be fixed in it's not ok? IDK what to tell you at that point.
IDK this is all seeming like a common internet post where someone wants attention so they just complain about stuff without really knowing what they're talking about.
