CVE-2026-52199Public exploit

Root code execution via unauthenticated ADB daemon

Published Jul 17, 2026 · Updated Jul 17, 2026

Incorrect access control in Generic OEM UZ801_v2.1 4G LTE Router 3.4.3 allows remote attackers on its LAN to execute code as root. The /sbin/adbd daemon listens on TCP port 7628 without authentication and accepts a standard ADB connection that opens an interactive root shell. Reachability requires access to the router's LAN or Wi-Fi network; successful access exposes the file system and permits root-level device control.
