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.
T1105 Ingress Tool Transfer Command And Control
Adversaries may transfer tools or other files from an external system into a compromised environment.
T1505.003 Web Shell Persistence
Adversaries may backdoor web servers with web shells to establish persistent access to systems.
T1608.002 Upload Tool Resource Development
Adversaries may upload tools to third-party or adversary controlled infrastructure to make it accessible during targeting.
Why these techniques?

Unrestricted file upload vulnerability in public-facing PHP web application (/native/admin/save-slider.php) enables exploitation of public-facing apps (T1190), ingress tool/malware transfer (T1105, T1608.002), and web shell deployment for RCE/persistence (T1505.003).

addresses: CWE-284 CWE-434

Hardware write-protect enforces access control on critical resources (e.g., firmware) independent of software state.

addresses: CWE-284

The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.

addresses: CWE-284

Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.

addresses: CWE-284

Supervision and review of access control activities directly detects and remediates improper access configurations or usages.

addresses: CWE-284

Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.

addresses: CWE-284

By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.

addresses: CWE-284

Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
