Fujifilm Printer Vulnerability: Protect Your Devices from DoS Attacks
A critical vulnerability has been discovered in Fujifilm printers, potentially allowing attackers to trigger denial-of-service (DoS) conditions. This means that malicious actors could remotely freeze your printer, disrupting your workflow and causing frustration. Here's what you need to know to protect your devices.
A typical Fujifilm printer. Keeping your firmware updated is crucial for security.
Understanding the Vulnerability
The vulnerability, identified as CVE-2025-48499, stems from an out-of-bounds write issue in FUJIFILM Business Innovation MFPs (multifunction printers). It affects the way these printers process Internet Printing Protocol (IPP) and Line Printer Daemon (LPD) packets. By sending a specially crafted packet, an attacker can cause the printer to freeze, requiring a manual reset to restore functionality.
This vulnerability has been assigned a CVSS v3.1 score of 5.3 (Medium severity) and a CVSS v4.0 score of 6.9 (Medium severity), indicating a moderate level of risk. While not the most severe vulnerability, the potential for disruption makes it important to address.
