US EditionMillions of Brother printers threatened by multiple serious vulnerabilities – enterprise and home printers at risk
- Rapid7 revealed on a Wednesday in 2025 that eight serious vulnerabilities affect 689 Brother printers, scanners, and label makers worldwide.
- The vulnerabilities stem from Brother's default password generation during manufacturing, which uses a serial number-based algorithm, leaving existing devices exposed unless passwords change.
- The most critical vulnerability, CVE-2024-51978, allows unauthenticated attackers to bypass authentication, take control of devices, and access connected systems, with six other flaws also exploitable without authentication.
- Brother issued security advisories and firmware updates fixing all vulnerabilities except CVE-2024-51978, which requires manufacturing process changes for full remediation, applying only to devices made after March 2025.
- Users should immediately change default admin passwords and apply firmware updates while restricting admin interface access to mitigate risks until new devices replace vulnerable models.
