CVE-2026-10293 · Severity: high · CVSS 8.8 · Published 2026-06-01

UTT HiPER series routers, which are used to manage network traffic and security for small to medium businesses, contain a critical security flaw in their firewall configuration interface. An attacker with basic user credentials can send a specially crafted request to the device to trigger a memory overflow. This can lead to a complete system crash or allow the attacker to gain unauthorized control over the router, potentially compromising the entire network's security and availability.

## Technical details

A stack-based buffer overflow exists in the UTT HiPER 1200GW (up to 2.5.3-170306) and 1250GW (up to v3.2.7-210907-180535) within the /goform/formFireWall endpoint. The vulnerability is caused by the unsafe use of the 'strcpy' function when processing the 'Profile' or 'destAddr' arguments. Specifically, user-controlled data retrieved via 'websGetVar' is copied into a fixed-size buffer at a specific offset within a configuration structure without length validation. An attacker with low-privileged network access can exploit this by sending a POST request with a long payload, leading to memory corruption, denial of service, or remote code execution. A public proof-of-concept (PoC) has been disclosed.

## Affected products

- UTT HiPER 1200GW up to 2.5.3-170306
- UTT HiPER 1250GW <=v3.2.7-210907-180535
