CVE-2023-41346
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 · uneditedASUS RT-AX55’s authentication-related function has a vulnerability of insufficient filtering of special characters within its token-refresh module. An authenticated remote attacker can exploit this vulnerability to perform a Command Injection attack to execute arbitrary commands, disrupt the system or terminate services.
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 confidenceThe ASUS RT-AX55 router contains a command injection vulnerability in its authentication token-refresh module. The vulnerability stems from insufficient filtering of special characters in user-supplied input within the token-refresh functionality. An authenticated remote attacker can exploit this to inject and execute arbitrary operating system commands with the privileges of the affected 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 the device modelAccess the router web interface or check the device label to confirm it is an ASUS RT-AX55 modelAffected if Device is not an ASUS RT-AX55, then it is not affected by this specific CVE
-
Check the installed firmware versionLog into the router administration panel, navigate to Firmware Version or System Settings, and record the current firmware build number. Alternatively, check via command line if accessible or look for version info in the web interface footerAffected if Firmware version equals 3.0.0.4.386.51598 exactly, then the installed version matches the affected version listed in the CVE
-
Verify if remote management is enabledIn the router web interface, go to Administration > System > Remote Management (or similar path depending on firmware) and check if Remote Management Access from Internet is enabledAffected if Remote management is exposed to the internet, the attack surface is wider for remote exploitation
-
Confirm token-refresh functionality existsCheck router firmware settings for any authentication, token, or session management modules. In the web interface, look for options related to token refresh, session timeout, or authentication settings under Administration or Security settingsAffected if Token-refresh module is present in the firmware, which is the vulnerable component
-
Review access logs for suspicious authentication activityIn the router admin panel, navigate to System Log or Traffic Monitor and search for repeated authentication attempts, unusual IP sources, or command-like strings in the logsAffected if Log entries show unauthorized authentication attempts, unusual command patterns, or unexpected IP addresses accessing the management interface
You are affected if you are running an ASUS RT-AX55 with firmware version 3.0.0.4.386.51598 and the token-refresh authentication module is present and accessible.

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 latest ASUS firmware update for RT-AX55 when available. As immediate workarounds, disable remote management access from the internet, enforce strong authentication credentials, and monitor for unauthorized access attempts.
