Reading this I'm almost certain the firewall vendor is Palo Alto Networks. They included a PAN-OS setting verbatim and the SELinux config matches my experience.

Why does a world-class firewall stack need PHP? I'm sure PAN-OS has some neat DPI features, but I would love to see firewalls that are implemented in FPGA, where the tasking was compiled down to gates to be performed deterministically, much like the low port count network switches we have today.

Yes, in 2005 you choose PHP, but in 20 years of operation, you don't revisit reconsider your architectural considerations? A fantastic avenue for hardening any product would be to replace a ~2MSLOC component (the PHP interpreter) with a 10K SLOC daemon that does only what you need.
When you're a startup, expediency and funding prevent this, but by the time you're selling "solutions" and baking designs into ASICs you could have prevented this attack by putting a fraction of the effort into software.
This is great to say with the benefit of hindsight but nobody is changing the underlying language of their well established product for literally no reason.
And that is even with the assumption that other languages don't have issues - they do.
For some reason I’m not allowed to respond to the child comment so I’m putting this here:
Perl 5 was released in 1994. Palo Alto Networks was founded in 2005, so Perl 5 was certainly available when they built their first products and would have been a superior choice to either PHP or Perl 4.
This makes me kinda furious. The us government makes me do so much goddamned work to comply with their cyber security regulations (only about half of which actually contribute to my security posture), and here they are running their fucking firewall management page publicly exposed (the globalprotect portal was not vulnerable, only the _actual_ management page).
Remember that the non-defense sector of the government has been having cuts for decades and lots of important work is outsourced to rotating contract teams. This is definitely unacceptable but I'd bet there were more than a few people there who were profoundly unsurprised that the backlog caught up with them.
The title is misleading as the article says "including systems in a US government-affiliated environment" which reads more like a 3rd party the government is contracted with versus actual government systems.
