Vulnerability details

Yarbo firmware v2.3.9 contains hardcoded administrative credentials embedded in the firmware image. These credentials are identical across all devices running this firmware and cannot be changed or removed by end users, enabling trivial unauthorized access to device management interfaces by…

MITRE ATT&CK Enterprise TechniquesAI

T1078 Valid Accounts Stealth
Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.
T1078.001 Default Accounts Stealth
Adversaries may obtain and abuse credentials of a default account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.
T1552 Unsecured Credentials Credential Access
Adversaries may search compromised systems to find and obtain insecurely stored credentials.
Why these techniques?

Hardcoded identical admin credentials in firmware directly enable use of valid/default accounts (T1078/T1078.001) for unauthorized access and expose unsecured credentials (T1552) extractable from the image.
