Report: D-Link DWR-M960 Firmware (vulnerabilities, features, installation, changelog, recommendations)

Summary

Device: D-Link DWR‑M960 (4G LTE modem/router)
Focus: firmware — features, known vulnerabilities, installation/upgrade process, rollback, secure configuration, integrity checks, and recommendations.
Date: April 10, 2026

Firmware overview

Purpose: Embedded Linux-based firmware providing router, modem (LTE), NAT, DHCP, DNS, firewall, VPN passthrough, web admin UI, and optional cloud management.
Typical file formats: .bin or .img for full firmware images; incremental packages for UI/feature patches.
Update methods: Web UI upload, TR-069/ACS (if enabled), TFTP (recovery), or vendor-provided Windows utility.

Common firmware components and architecture

Bootloader: U-Boot or vendor variant — initializes hardware, network, and loads kernel.
Kernel: Linux kernel (version varies by firmware) with drivers for Qualcomm/Mediatek modem chipset, Wi‑Fi chipset drivers, NAT/conntrack modules.
Root filesystem: squashfs or jffs2 containing web UI (Lua/PHP), management daemons (netifd/odm), PPP/Modem manager, and busybox toolchain.
Partition layout: bootloader, kernel, rootfs, optional recovery partition, nvram/config partition.
Update mechanism: atomic update that writes new kernel+rootfs and updates bootloader env to boot new image; some versions support A/B.

Security history / known vulnerabilities (summary of typical issues to check)

Default credentials: Historically many D-Link devices used default admin/admin or admin/blank; ensure changed.
Hardcoded credentials/backdoor accounts: Some vendor firmwares have had hidden accounts or debug features.
CSRF/Stored XSS in web UI: Older web interfaces often vulnerable to CSRF and XSS allowing remote admin operations.
Authentication bypass: Flaws allowing access to admin UI via crafted URLs or API endpoints.
Remote code execution (RCE): Via vulnerable services (mini_httpd, old CGI scripts) or buffer overflows in parsers/modem drivers.
UPnP / WAN-side service exposure: UPnP misconfiguration allowing port mapping from WAN.
TR-069 ACS misconfiguration: Allows remote firmware push or retrieval of credentials if not authenticated.
Insecure firmware update: Lack of signature verification enabling installation of unsigned/modified firmware.
Outdated open-source components: Old Linux kernel, BusyBox, OpenSSL/LibreSSL with known CVEs.
LTE/modem baseband issues: Proprietary modem firmware vulnerabilities that may impact privacy or connectivity. Note: Specific CVE numbers and dates depend on firmware version; review vendor advisories for exact details.

How to identify current firmware and obtain official update

Check Web UI (Status or System page) for firmware version string and build date.
SSH/telnet (if available) run uname -a and check /etc/version, /proc/cmdline, md5sum of /bin/webserver etc.
Serial console: Bootloader prompt shows environment variables (bootcmd, firmware partition labels) and image version.
Obtain official firmware from D-Link support site for your hardware revision (matching HW revision printed on device label).
Verify release notes for changelog and security fixes.

Verifying firmware integrity and authenticity

Prefer vendor-signed images. Check vendor documentation if images are cryptographically signed.
If vendor provides SHA256/MD5 checksums, verify after download.
Use HTTPS download from official site; validate TLS certificate in browser.
For advanced users with serial: dump flash and compare with official image; check bootloader signature verification behavior (U-Boot verifying signature or kernel image signature).

Recommended upgrade procedure (safe steps)

Verify correct model and hardware revision printed on device sticker.
Backup current configuration via Web UI (export settings).
Note current firmware version and serial number.
Download official firmware matching HW rev; verify checksum.
Connect via wired Ethernet to avoid interruptions.
Reboot to stable state; disable scheduled tasks and remote management during upgrade.
Use Web UI firmware upgrade page; upload image and start.
Wait until device reboots fully. Do NOT power‑cycle during write.
After upgrade, perform factory reset if vendor recommends (resolves config incompatibilities).
Restore minimal configuration; change default passwords; re-enable services carefully.
Verify connectivity (WAN, LTE, Wi‑Fi) and check logs for errors.
If upgrade fails, use TFTP/serial recovery per vendor instructions to reflash.

Rollback and recovery

If image includes A/B partitions, boot into previous partition via bootloader env or UI rollback option.
If bricked: use TFTP recovery mode or serial console + JTAG to reflash bootloader and firmware.
Keep a copy of last-known-good firmware and vendor recovery tools.

Secure configuration post‑upgrade (minimal checklist)

Change default admin password to strong unique password.
Disable remote administration from WAN unless needed; if needed, restrict by IP and use HTTPS.
Disable legacy insecure services (telnet, FTP); enable SSH if needed (and restrict keys).
Disable UPnP on WAN side.
Disable WPS.
Use WPA3/WPA2‑AES with a strong passphrase; separate guest SSID.
Keep TR-069/ACS disabled unless required and secure with authentication.
Configure firewall to block inbound management ports from WAN.
Enable automatic firmware updates if vendor provides secure signed updates.
Limit diagnostic/logging exposure; rotate any SNMP community strings.
Monitor logs for unexpected admin logins and reboots.

Integrity monitoring and detection of compromise

Check system uptime and unexpected reboots.
Review running processes (ps) and open ports (netstat -anp).
Verify binaries’ checksums against a fresh firmware image.
Look for persistence mechanisms: new crontab entries, modified /etc/init.d scripts, unauthorized users in /etc/passwd.
Monitor outbound connections to unknown hosts from device.
If suspect compromise, factory-reset and reflash from verified vendor image; change all credentials and any downstream credentials (e.g., PPPoE, Wi‑Fi keys).

Developer/advanced notes for auditors

Inspect bootloader env variables (via serial/U‑Boot) for update URLs, recovery IP, and bootcmd.
Review /proc/mtd and partition map; extract partitions using mtd-utils.
Mount squashfs root and inspect web UI CGI/JS for client-side vulnerabilities.
Search firmware for hardcoded secrets: strings, grep for "password", "admin", "ftp", "telnet", "root:".
Identify kernel version and run known-CVE checks for that kernel and included packages (OpenSSL, dropbear, busybox).
Check whether firmware uses signature verification (verify calls in U‑Boot or fw_setenv).
Reverse engineer modem-control daemons to see AT command logs or exposed AT interfaces.

Recommended mitigations by priority

Immediate: apply latest official firmware with security fixes; change default admin password; disable remote admin.
High: disable telnet/FTP, disable WPS, disable UPnP WAN, restrict TR‑069.
Medium: enable HTTPS for admin, limit management by IP, use strong Wi‑Fi settings.
Low: enable automatic updates (if secure), monitor logs, periodic firmware integrity checks.

Changelog and version tracking (how to maintain a record)

Maintain spreadsheet: device serial, HW revision, current firmware version/date, last update date, notes.
Subscribe to vendor security advisories and general IoT/CPE CVE feeds.
Periodically (quarterly) check for new firmware and test on staging device before fleet rollout.

Example commands (for advanced users with shell/SSH)

Check kernel/version:
```
uname -a
cat /etc/version
```
List partitions:
```
cat /proc/mtd
```
Check running processes and open ports:
```
ps | sort
netstat -tulpen
```

Compute checksum:

md5sum /bin/httpd
sha256sum /tmp/firmware.bin
