CVE-2024-29671
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 · uneditedBuffer Overflow vulnerability in NEXTU FLATA AX1500 Router v.1.0.2 allows a remote attacker to execute arbitrary code via the POST request handler component.
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 confidenceA buffer overflow vulnerability exists in the POST request handler of the NEXTU FLATA AX1500 Router firmware version 1.0.2. The vulnerability allows remote attackers to overflow a buffer in the HTTP POST parameter processing, leading to arbitrary code execution with elevated privileges.

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 CLI and check the device model information. Look for 'FLATA AX1500' or 'NEXTU' in the status page, device info, or system log.Affected if The device is NOT a NEXTU FLATA AX1500 router - the CVE does not apply to other models.
-
Check the firmware versionIn the router web interface, navigate to System Settings, Firmware Upgrade, or Status page. Locate the firmware version field. Alternatively, check via CLI using 'cat /proc/version' or 'ver' command if SSH/Telnet access is available.Affected if The firmware version is 1.0.2 exactly. Versions before or after 1.0.2 may have different vulnerability status; if your version differs from 1.0.2, compare it to the affected range.
-
Verify if remote management is enabledIn the router web interface, go to Remote Management, Administration, or Access Control settings. Check if 'Enable Remote Management' or 'Allow Remote Administration' is turned ON. Also check the allowed IP range configuration.Affected if Remote management is enabled and accessible from the WAN interface - this is required for remote exploitation. If remote management is disabled and only LAN access is permitted, the attack surface is significantly reduced.
-
Confirm HTTP POST handler is exposedAttempt to send an HTTP POST request to the router's WAN IP on common remote management ports (80, 443, 8080). Use a tool like curl: curl -X POST http://<WAN_IP>/ -d 'test=data'. Check if the router responds to POST requests from outside the local network.Affected if The router responds to HTTP POST requests from external IPs on the remote management interface - this confirms the vulnerable component is network-accessible.
You are affected if you have a NEXTU FLATA AX1500 router running firmware version 1.0.2 with remote management enabled and the HTTP POST handler 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 dataContact NEXTU for available firmware updates; if unavailable, disable remote management interfaces, restrict administrative access to trusted IPs only, and implement network segmentation to limit exposure.
