Related Threats

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?

OS command injection in public-facing web CGI (/var/www/cgi-bin/upgrade.cgi) via uploadedFile argument enables exploitation of public-facing application (T1190), indirect command execution (T1202), and Unix shell command execution (T1059.004).
