CP2026-001 Vulnerabilities Mitigation/Remediation for Small Office Multifunction Printers and Laser Printers

 

 

Multiple vulnerabilities have been identified in certain Small Office Multifunction Printers and Laser Printers.
These vulnerabilities indicate the possibility that, if a product is connected directly to the Internet without using a router (wired or Wi-Fi), an unauthenticated remote attacker could trigger a buffer overflow or invalid free, potentially leading to arbitrary code execution and/or a Denial-of-Service (DoS) attack.
