T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
Why these techniques?

Missing authorization on public endpoint directly enables T1190 exploitation; resulting arbitrary JS injection into checkout pages enables client-side script execution via T1059.007.
