MegaRAC Default Credentials Vulnerability

MegaRAC devices come with built-in usernames and passwords that are publicly known, allowing attackers to gain unauthorized access to system management interfaces. This is critical because anyone with internet access can potentially take control of these devices.

The vulnerability stems from hardcoded default credentials in MegaRAC BMC firmware (CWE-798). An unauthenticated attacker can access the web interface or IPMI services using known default credentials, bypassing authentication controls and gaining administrative privileges with no additional prerequisites.
