CVE-2024-47005 in MFP
Summary
by MITRE • 10/25/2024
Sharp and Toshiba Tec MFPs provide configuration related APIs. They are expected to be called by administrative users only, but insufficiently restricted. A non-administrative user may execute some configuration APIs.

The vulnerability identified as CVE-2024-47005 affects multifunction printers manufactured by Sharp and Toshiba Tec, specifically targeting their configuration application programming interfaces. These devices are commonly deployed in enterprise environments where they serve as critical components for document management and printing operations. The affected printers implement configuration APIs that are designed to be accessible exclusively to administrative users with elevated privileges, ensuring that sensitive system settings and operational parameters remain protected from unauthorized modification. However, the implementation contains a critical flaw in access control mechanisms that allows unauthorized users to execute certain configuration functions through these APIs.
The technical flaw stems from insufficient input validation and access control enforcement within the printer's web-based management interface. The configuration APIs lack proper authentication checks and authorization verification, enabling any user with network access to the device to invoke specific administrative functions. This vulnerability manifests through the absence of role-based access control mechanisms that should validate whether the requesting user possesses the necessary privileges before executing sensitive operations. The flaw creates a path for privilege escalation where standard users can potentially modify critical printer settings, alter security configurations, or access restricted operational parameters that should only be available to system administrators.
The operational impact of this vulnerability extends beyond simple unauthorized access to potentially compromise the entire document management infrastructure. An attacker with basic network access could exploit this vulnerability to modify printer settings, redirect print jobs, alter user permissions, or disable security features. The implications are particularly concerning in enterprise environments where these printers may be connected to sensitive networks and handle confidential documents. The vulnerability could enable attackers to establish persistent access points within the network, potentially facilitating lateral movement and further compromising other system components. This flaw undermines the fundamental security model of the devices and creates opportunities for data exfiltration, man-in-the-middle attacks, or denial-of-service conditions that could disrupt business operations.
Organizations should implement immediate mitigations including network segmentation to restrict access to these devices, deployment of network access control policies, and enforcement of strong authentication mechanisms. The affected manufacturers should provide firmware updates with proper access control enforcement and input validation. Security teams should conduct comprehensive audits of printer configurations and monitor for unauthorized access attempts. This vulnerability aligns with CWE-285 which addresses improper authorization issues, and represents a significant concern under ATT&CK framework category T1078 for valid accounts and T1566 for spearphishing attacks that could leverage this weakness to gain unauthorized access. Regular security assessments and network monitoring should be implemented to detect potential exploitation attempts and ensure continued protection of these critical networked devices.
