Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1105 Ingress Tool Transfer Command And Control
Adversaries may transfer tools or other files from an external system into a compromised environment.
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.
T1499.001 OS Exhaustion Flood Impact
Adversaries may launch a denial of service (DoS) attack targeting an endpoint's operating system (OS).
Why these techniques?

Missing authentication on /api/files/upload enables exploitation of public-facing web application (T1190), unauthorized ingress of tools or malware via file upload (T1105), and OS exhaustion DoS by filling server storage (T1499.001).
