VAR-202206-0191
Vulnerability from variot - Updated: 2025-01-30 21:45USR IOT 4G LTE Industrial Cellular VPN Router v1.0.36 was discovered to contain hard-coded credentials for its highest privileged account. The credentials cannot be altered through normal operation of the device. usr-g808 firmware, usr-g807 firmware, usr-g806 firmware etc. usr The product contains a vulnerability related to the use of hardcoded credentials.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. USR-G806 adopts high performance embedded CPU whichcan support 580MHz working frequency and can be widely used in Smart Grid,Smart Home, public bus and Vending machine for data transmission at highspeed. USR-G806 supports various functions such as APN card, VPN, WIFIDOG,flow control and has many advantages including high reliability, simpleoperation, reasonable price. USR-G806 supports WAN interface, LAN interface,WLAN interface, 4G interface. The 'usr' account with password 'www.usr.cn' has the highestprivileges on the device. The password is also the default WLAN password.Tested on: GNU/Linux 3.10.14 (mips)OpenWrt/Linaro GCC 4.8-2014.04Ralink SoC MT7628 PCIe RC modeBusyBox v1.22.1uhttpdLua

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
