CVE-2025-52053
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 · uneditedTOTOLINK X6000R V9.4.0cu.1360_B20241207 was found to contain a command injection vulnerability in the sub_417D74 function via the file_name parameter. This vulnerability allows unauthenticated attackers to execute arbitrary commands via a crafted request.
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 · high confidenceThe TOTOLINK X6000R router firmware V9.4.0cu.1360_B20241207 contains an unauthenticated command injection vulnerability in the sub_417D74 function through the file_name parameter, allowing remote attackers to execute arbitrary OS commands by injecting shell metacharacters into this parameter.

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 modelCheck if the device is a TOTOLINK X6000R router by inspecting the web interface login page, device label, or using network discovery tools to examine device identification stringsAffected if Device is not a TOTOLINK X6000R model
-
Check firmware versionAccess the router web management interface and navigate to System Status or Firmware Upgrade page to view the installed firmware version, or use SSH/Telnet if enabled to run 'cat /proc/version' or check /etc/version fileAffected if Firmware version is 9.4.0cu.1360_b20241207 exactly
-
Verify vulnerable parameter accessibilitySend an HTTP request to the router's web interface endpoint that processes the file_name parameter in the sub_417D74 function; if the endpoint responds, the parameter is exposedAffected if The endpoint handling file_name parameter is reachable from the network
You are affected if you have a TOTOLINK X6000R router running firmware version 9.4.0cu.1360_b20241207 with the file_name parameter endpoint accessible on your network.

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 the vendor-supplied firmware patch when available; until then, restrict network access to the device's management interface or implement firewall rules to prevent unauthorized external access to the vulnerable endpoint.
