MITRE ATT&CK Enterprise TechniquesAI

T1552.001 Credentials In Files Credential Access
Adversaries may search local file systems and remote file shares for files containing insecurely stored credentials.
T1078.003 Local Accounts Stealth
Adversaries may obtain and abuse credentials of a local account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.
Why these techniques?

The vulnerability exposes hardcoded administrator credentials in device firmware due to incorrect access control, enabling discovery of credentials in files (T1081, T1552.001) and use of valid local accounts (T1078.003).
