CVE-2025-63579 in Command Center RX TASKalfa 2552ci
Summary
by MITRE • 07/09/2026
Unauthorized use of Kyocera printers, allows all information stored in the Kyocera address book to be exported. The security measure that encrypts incoming data ian be bypassed with this vulnerability, allowing encrypted data to be decrypted. Passwords and other sensitive information can be obtained. This affects Kyocera Command Center RX TASKalfa 2552ci, TASKalfa 3252ci, TASKalfa 2553ci, TASKalfa 3253ci, TASKalfa 3554ci, TASKalfa 4052ci, TASKalfa 5052ci, TASKalfa 6052ci, TASKalfa 7052ci, TASKalfa 8052ci, TASKalfa 7353ci, TASKalfa 8353ci, TASKalfa 2554ci, TASKalfa 3254ci, TASKalfa 505.

This vulnerability represents a critical security flaw in Kyocera's Command Center RX series of multifunction devices that fundamentally compromises the confidentiality and integrity of sensitive information stored within these systems. The issue stems from inadequate access controls and cryptographic implementation weaknesses that allow unauthorized users to bypass established security measures. The vulnerability specifically affects multiple models including the TASKalfa 2552ci, 3252ci, 2553ci, 3253ci, 3554ci, 4052ci, 5052ci, 6052ci, 7052ci, 8052ci, 7353ci, 8353ci, 2554ci, 3254ci, and 505 models, indicating a widespread exposure across the product line. The flaw enables attackers to export all information contained in the Kyocera address book, which typically contains contact details, email addresses, phone numbers, and potentially other sensitive personal or corporate data.
The technical nature of this vulnerability involves the bypassing of encryption mechanisms that are supposed to protect incoming data transfers within these devices. This represents a failure in cryptographic implementation where the security controls designed to encrypt data cannot properly prevent unauthorized access to encrypted information. The weakness creates an attack surface that allows malicious actors to decrypt data that should remain protected, effectively undermining the entire encryption strategy employed by these devices. When combined with the ability to access address book information, this vulnerability provides attackers with a comprehensive view of potentially sensitive contact information and communication details that could be used for social engineering attacks or further exploitation.
The operational impact of this vulnerability extends beyond simple data exposure to encompass broader security implications for organizations relying on these devices for their document management and communication infrastructure. Attackers who exploit this vulnerability can obtain passwords, login credentials, and other sensitive information that may provide access to additional systems within the network. This creates a potential escalation path where initial unauthorized access to printer address books can lead to more significant security breaches. The vulnerability's impact is particularly concerning given that these are multifunction devices that often serve as central points for office communication and document handling, making them attractive targets for cybercriminals seeking to establish persistent access or conduct reconnaissance activities.
From a cybersecurity framework perspective, this vulnerability aligns with multiple CWE classifications including CWE-284 for improper access control and CWE-310 for cryptographic issues. The attack patterns associated with this flaw would map to ATT&CK techniques such as T1071.004 for application layer protocols and T1566 for credential harvesting through social engineering or direct system compromise. Organizations should implement immediate mitigations including network segmentation of these devices, disabling unnecessary services, applying firmware updates when available, and monitoring for unauthorized access attempts. Additionally, organizations must conduct thorough risk assessments to determine if any sensitive information has been compromised and consider implementing additional authentication mechanisms beyond the default configurations provided by Kyocera. The vulnerability highlights the critical importance of proper cryptographic implementation and access control measures in networked devices that handle sensitive information.
