Related Threats

MITRE ATT&CK Enterprise TechniquesAI

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.
T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Missing authorization in public-facing /storage/ endpoints enables unauthenticated remote exploitation of the web application (T1190) to arbitrarily manipulate admin storage quotas, facilitating endpoint denial of service through application quota exhaustion or restriction (T1499.004).
