CVE-2024-48441
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 · uneditedWuhan Tianyu Information Industry Co., Ltd Tianyu CPE Router CommonCPExCPETS_v3.2.468.11.04_P4 was discovered to contain a command injection vulnerability via the component at_command.asp.
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 Tianyu CPE Router version CommonCPExCPETS_v3.2.468.11.04_P4 contains a command injection vulnerability in the at_command.asp web component. An attacker can inject and execute arbitrary operating system commands through unsanitized user input processed by this ASP page.

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 CPE router model and firmware versionAccess the router's web management interface or check the device's system information page. Look for the firmware version string CommonCPExCPETS_v3.2.468.11.04_P4 or similar Tianyu CPE firmware versions.Affected if The firmware version matches CommonCPExCPETS_v3.2.468.11.04_P4 or falls within the Tianyu CPE firmware line containing this web component.
-
Confirm the at_command.asp component existsAttempt to access the URL path /at_command.asp on the router's web interface (e.g., http://router-ip/at_command.asp). Check if the page loads or returns a valid HTTP response.Affected if The at_command.asp page is present and accessible, indicating the vulnerable component is enabled.
-
Verify remote management access is enabledCheck the router's web interface settings for Remote Management or Web GUI access from WAN. Look for options like 'Enable Remote Management' or 'Allow management from WAN' that are turned on.Affected if Remote management access is enabled, allowing unauthenticated or weakly authenticated access from external networks.
-
Check network exposure of the management interfaceReview firewall rules or access control lists to determine if the router's web management port (typically 80 or 443) is exposed to untrusted networks or the internet. Use external port scanning tools to confirm.Affected if The router's management interface is reachable from untrusted networks or the public internet.
-
Assess authentication requirements for at_command.aspTest whether the at_command.asp endpoint requires authentication. Attempt to access it without logging in or with standard user credentials to see if command injection parameters are accepted.Affected if The endpoint accepts commands without proper authentication or input sanitization validation.
A user is affected if they operate a Tianyu CPE router with the CommonCPExCPETS_v3.2.468.11.04_P4 firmware where the at_command.asp component is accessible and the management interface is exposed to untrusted networks.

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 dataImplement strict input validation and sanitization on all user-supplied parameters in at_command.asp. Consider using parameterized commands or whitelist-based validation to prevent command injection. If possible, restrict access to this administrative interface.
