CVE-2025-63579
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnauthorized 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis vulnerability in Kyocera TASKalfa printers allows unauthorized actors to bypass encryption protecting incoming data, enabling extraction of the entire address book containing passwords and other sensitive information. The attack exploits a weakness in the encryption mechanism that secures data at rest on the device.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device modelAccess the printer web interface or print a status page to confirm the device is a Kyocera TASKalfa printerAffected if Device is a Kyocera TASKalfa model and runs firmware without the security patch
-
Check firmware versionNavigate to the printer settings menu or web interface and locate the firmware version information. Compare against vendor release notes for CVE-2025-63579.Affected if Firmware version is older than the patched version that addresses this vulnerability
-
Verify address book encryption statusAccess the device address book settings through the web interface or control panel. Look for encryption status indicators or encryption configuration options.Affected if Address book encryption is disabled or shows as compromised/unencrypted
-
Check for unauthorized address book accessReview device audit logs or access logs for unusual export or retrieval of address book data, especially from unknown IP addresses or after-hours activity.Affected if Suspicious address book export activities are logged without corresponding legitimate admin actions
A Kyocera TASKalfa printer is affected if it is running unpatched firmware AND has address book encryption disabled or shows evidence of unauthorized address book extraction.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied firmware patches to all affected Kyocera devices and verify that address book encryption is functioning correctly post-patch.
