MITRE ATT&CK Enterprise TechniquesAI

T1505.003 Web Shell Persistence
Adversaries may backdoor web servers with web shells to establish persistent access to systems.
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.
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 in public-facing web app (/pages/product.php) enables exploitation of public-facing applications (T1190), staging by uploading tools (T1608.002), and deployment/execution of web shells (T1100) leading to RCE.

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.
