> Equifax, however, did not fully patch its systems. Equifax’s Automated Consumer Interview System (ACIS), a custom-built internet-facing consumer dispute portal developed in the 1970s, was running a version of Apache Struts containing the vulnerability. Equifax did not patch the Apache Struts software located within ACIS, leaving its systems and data exposed.

1970s? Am I reading that right? HTML wasn't even developed yet.

Most likely they had a web front end that talks to the legacy system. Very common in big companies.

It was probably developed very quickly, possibly outsourced, and just stuck in front of the older system with minimal re-engineering.

Many years ago, I worked on a system that put an X Windows front end in front of a mainframe app that used a 3270 emulator to interact with parts of the legacy app. I imagine this is somewhat similar.

Yes. ACIS is still a terminal-based mainframe application, but it's now fronted by a bunch of shitty Java apps that function as its API.
