Authentication Bypass Vulnerability in Operating System Root User Credentials by Vendor

CVE-2025-48413

What is CVE-2025-48413?

The vulnerability exposes hard-coded password hashes for the root user within the /etc/passwd and /etc/shadow files, due to an oversight in the update files. These credentials are included by default, presenting significant security risks as users cannot alter or delete the hard-coded passwords. This flaw allows an attacker to leverage these credentials to gain unauthorized access via SSH or potentially through direct physical access methods such as UART shell, making it imperative for affected users to assess their systems for any potential exploitation.
