A total of 689 printer models from Brother, along with 53 other models from Fujifilm, Toshiba, and Konica Minolta, come with a default administrator password that remote attackers can generate.
This crucial vulnerability can be chained with other vulnerabilities discovered by Rapid7 to determine the admin password, take control of devices, perform remote code execution, crash them, or pivot within the networks they're connected to.Not all of the flaws affect every one of the 689 Brother printer models, but other manufacturers, including Fujifilm (46 models), Konica Minolta (6), Ricoh (5), and Toshiba (2), are impacted as well.
