CVE-2024-27910
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 · uneditedA vulnerability was reported in some Lenovo Printers that could allow an unauthenticated attacker to reboot the printer without authentication.
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 allows an unauthenticated network attacker to remotely reboot Lenovo printers without any authentication, likely due to a missing or bypassed authentication check in the printer's web interface or network management service.

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 Lenovo printers on your networkScan your network for devices with Lenovo vendor identifiers or check your asset inventory for Lenovo printer models. Note the IP addresses and hostnames of all Lenovo printing devices.Affected if You have any Lenovo printers deployed on your network.
-
Determine the firmware version of each Lenovo printerAccess the printer's web interface (http://<printer-ip>) and navigate to the Settings or About page to find the firmware version. Alternatively, print a configuration page from the printer control panel that typically lists the firmware version.Affected if The installed firmware version has not been updated to include the CVE-2024-27910 fix from Lenovo.
-
Verify if the printer web interface is network-accessibleFrom a machine on the same network segment (or outside it if externally exposed), attempt to reach http://<printer-ip> in a browser or via curl/curl -I http://<printer-ip>. A successful HTTP response indicates the web interface is accessible.Affected if The printer web management interface responds to HTTP requests from your network without requiring authentication first.
-
Confirm the reboot endpoint accepts unauthenticated requestsSend a POST request to common reboot endpoints (such as /rbeep or /reboot) using curl -X POST http://<printer-ip>/rbeep without providing any credentials. If the printer initiates a reboot without returning a 401 authentication error, the vulnerability is present.Affected if The printer reboots or accepts the reboot command without returning an HTTP 401/403 error indicating authentication is required.
You are affected if you have any Lenovo printers with network-accessible web interfaces that allow unauthenticated remote reboot commands.

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 available firmware updates from Lenovo for affected printer models. If patches are unavailable, isolate printers on a restricted network segment to limit exposure to unauthenticated attackers.
