MITRE ATT&CK Enterprise TechniquesAI

T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
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.
T1202 Indirect Command Execution Stealth
Adversaries may abuse utilities that allow for command execution to bypass security restrictions that limit the use of command-line interpreters.
Why these techniques?

The remote command injection vulnerability in the D-Link DIR-823X router's web interface (/goform/delete_prohibiting) via the delvalue parameter enables exploitation of a public-facing application (T1190), execution of arbitrary Unix shell commands (T1059.004), and indirect command execution through the uci_del function (T1202).
