These devices tend to only support weak authentication mechanisms, even in the best of cases, and are rarely kept up to date with firmware updates to address security issues. While this is true for most LAN-centric technologies, this is especially true for printers and scanners, which are popular targets for opportunistic attackers. Note that printer credentials are not themselves at risk (except in the case of reused passwords, of course), but credentials to services the printer is normally expected to store scanned documents are exposed via this vulnerability.\n\n# Remediation\n\nFirst and foremost, MFPs should under no circumstance be able to be reached directly across the internet. In the case of SMB credentials, those might then be leveraged to establish a presence in the target networks' Windows domain.\n\nDepending on how those external services are administered, the attacker may also be able to collect prior (and future) print/scan jobs originating from the targeted printer, but the primary value of this vulnerability is lateral movement within the network. Review the above response for credentials in objects such as 'login_password', 'login_name'\")\n \n\n# Impact\n\nThe most likely attack scenario involving this vulnerability would be an attacker, who is already inside the LAN perimeter, leveraging their ability to communicate directly with affected printers to learn the usernames and passwords to stored SMB and FTP file servers.
