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.
T1505.003 Web Shell Persistence
Adversaries may backdoor web servers with web shells to establish persistent access to systems.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
Why these techniques?

Authenticated RCE via unsanitized PHP input in CMS Made Simple's User Defined Tags module enables exploitation of public-facing web apps (T1190), server software component abuse similar to web shells (T1505.003), and Unix shell command execution (T1059.004).
