CVE-2024-13502
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 · uneditedImproper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in Newtec/iDirect NTC2218, NTC2250, NTC2299 on Linux, PowerPC, ARM allows Local Code Inclusion.This issue affects NTC2218, NTC2250, NTC2299: from 1.0.1.1 through 2.2.6.19. The `commit_multicast` page used to configure multicasts in the modem's web administration interface uses improperly parses incoming data from the request before passing it to an `eval` statement in a bash script. This allows attackers to inject arbitrary shell commands.
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 confidenceOS Command Injection vulnerability in Newtec/iDirect NTC2218, NTC2250, NTC2299 modems. The web administration interface's `commit_multicast` page fails to properly sanitize input before passing data to an `eval` statement in a bash script, enabling attackers to inject and execute arbitrary shell commands with the privileges of the web 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 web administration interface and check the status or system information page, or examine the device label/boot console output for the exact model number (NTC2218, NTC2250, or NTC2299)Affected if The device model is NTC2218, NTC2250, or NTC2299
-
Verify web administration interface is enabledAttempt to access the device web interface on the default HTTP/HTTPS ports (typically 80 or 443) or check the device network configuration for active web service bindingsAffected if The web administration interface is accessible and responding
-
Confirm the commit_multicast functionality existsNavigate to or probe for the /commit_multicast endpoint on the web interface (e.g., http://<device-ip>/commit_multicast)Affected if The commit_multicast page or endpoint exists and loads without being blocked or returning a 404
-
Check firmware version if displayedLocate the firmware version information in the web interface status, system info, or about page, and compare against any vendor-released patch version numbersAffected if The firmware version matches the affected models and has not been patched to a version that addresses CVE-2024-13502
Your environment is affected if you have a Newtec/iDirect NTC2218, NTC2250, or NTC2299 modem with the web administration interface enabled and the commit_multicast feature present, particularly if the firmware has not been updated to a patched version.

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 dataContact vendor for firmware patch to remove vulnerable eval() call and implement proper input validation; until patch available, isolate affected devices on restricted network segments and disable web administration interface if not operationally critical.
