The AT&T U-verse 9.2.2h0d83 firmware for the Arris NVG589 and NVG599 devices, when IP Passthrough mode is not used, configures an unauthenticated proxy service on WAN TCP port 49152, which allows remote attackers to establish arbitrary TCP connections to intranet hosts by sending \x2a\xce\x01 followed by other predictable values.

Security readout for executives and security teams

Certain AT&T U-verse Arris NVG589 and NVG599 gateways expose a WAN-side proxy service in affected firmware. If present, an outside attacker could use the gateway to reach internal network hosts, weakening the normal perimeter boundary. Exposure is likely limited to Arris NVG589/NVG599 devices on AT&T U-verse firmware 9.2.2h0d83, internet-facing, and not using IP Passthrough mode. Treat this as a perimeter exposure issue. Prioritize affected gateway inventory and remediation, especially for offices or small sites relying on these devices for network separation. Mitigation focus: Inventory Arris NVG589 and NVG599 gateways and confirm firmware versions.; Check AT&T or Arris guidance for firmware updates or replacement options.; Block unsolicited WAN access to TCP port 49152 where upstream controls allow..
