CVE-2026-75501 (GCVE-0-2026-75501)
Vulnerability from cvelistv5
Published
2026-08-21 14:47
Modified
2026-08-25 19:26
Summary
A vulnerability in the Calix EXOS firmware for the GS7 XGS (GS5239XG) residential router allows unauthenticated remote attackers to modify NAT port‑forwarding rules via the UPnP WANIPConnection service. The device exposes the MiniUPnPd control endpoint on the WAN interface on TCP port 5000 without access controls. A remote attacker can send crafted SOAP requests to add, delete, or enumerate port mappings, or to query the external IP address, without authentication. Successful exploitation may enable bypass of the firewall/NAT boundary and exposure of internal LAN services to the public internet.
