D-Link Go-RT-AC750 GORTAC750_revA_v101b03 & GO-RT-AC750_revB_FWv200b02 is vulnerable to command injection via /htdocs/upnpinc/gena.php.
D-Link Go-RT-AC750 GORTAC750_revA_v101b03 & GO-RT-AC750_revB_FWv200b02 is vulnerable to Buffer Overflow via authenticationcgi_main.
D-Link Go-RT-AC750 GORTAC750_revA_v101b03 and GO-RT-AC750_revB_FWv200b02 are vulnerable to Command Injection via cgibin, ssdpcgi_main.
D-Link Go-RT-AC750 GORTAC750_revA_v101b03 and GO-RT-AC750_revB_FWv200b02 are vulnerable to Buffer Overflow via cgibin, hnap_main,
D-Link GO-RT-AC750 GORTAC750_revA_v101b03 and GO-RT-AC750_revB_FWv200b02 is vulnerable to Command Injection via /cgibin, hnap_main,
D-Link Go-RT-AC750 revA_v101b03 was discovered to contain a command injection vulnerability via the service parameter at soapcgi.main.
D-Link Go-RT-AC750 revA_v101b03 was discovered to contain a command injection vulnerability via the service parameter at genacgi_main.
D-Link Go-RT-AC750 revA_v101b03 was discovered to contain a command injection vulnerability via the service parameter at hedwig.cgi.
In D-LINK Go-RT-AC750 v101b03, the sprintf function in the sub_40E700 function within the cgibin is susceptible to stack overflow.
D-Link Go-RT-AC750 GORTAC750_A1_FW_v101b03 contains a stack-based buffer overflow via the function genacgi_main. This vulnerability allows attackers to enable telnet service via a specially crafted payload.
Commonly exposed ports
- Port 23 (Telnet) — Sends admin credentials unencrypted — a common target on older router firmware.
- Port 80 (HTTP admin panel) — The web admin UI; dangerous if remote/WAN administration is left enabled.
- Port 7547 (TR-069 (CWMP)) — ISP remote-management protocol — has been the entry point for several router botnets.
- Port 1900 (UPnP/SSDP) — Lets apps on your LAN open firewall holes automatically, sometimes without your knowledge.
Default credentials
From ProbeShield's own tested default-credential list (see probeshield.com/default-passwords/): "admin" / "d-link" or "admin" / "pass" over HTTP.
Hardening checklist
- Disable remote (WAN-side) administration unless you specifically need it.
- Turn off UPnP unless a specific app you trust requires it.
- Turn off WPS — it can let an attacker bypass your Wi-Fi password.
- Change the default admin username and password to something unique.
- Check for a firmware update in the router’s admin panel and apply it.
- Disable Telnet/SSH management access if you don’t actively use it.
Frequently asked questions
Is my D-Link GO RT Ac750 affected by these vulnerabilities? Only if you’re running a firmware version in the affected range listed above and haven’t updated. Check your router's admin panel for its current firmware version and compare it against the ranges below.
How do I update my D-Link GO RT Ac750's firmware? Log into the router's web admin panel (usually at its local IP address) and look for a Firmware Update or System Update section, or use the vendor's mobile app if it has one.
Does ProbeShield fix these vulnerabilities for me? No — ProbeShield scans your network and tells you what it finds (open ports, default credentials, outdated firmware signals) so you know what to fix, and how. It never changes your devices’ settings.
