| عنوان | Ziroom Smart Ziroom Smart Gateway (ZH-A0101) ZH-A0101 1.0.1.0 Backdoor |
|---|
| الوصف | The Ziroom Smart Gateway (model ZH-A0101) contains a factory-default Telnet backdoor listening on port 23 (or non-standard port 1022 in some scans). It uses weak/hardcoded default credentials (e.g., username: root/admin, password: admin or empty) granting full root shell access remotely.
The backdoor is enabled via a hard-coded startup script (/etc/init.d/telnet) that launches /usr/sbin/telnetd -l /bin/login.sh on boot, restoring default root access even after modifications.
This allows unauthenticated or weakly authenticated remote code execution with root privileges, leading to full device compromise and persistent backdoor access.
Affected: Confirmed on firmware x.x.x.x (released 2020-04-15). Potentially earlier versions.

Disclosure: Discovered and publicly disclosed 2026-01-23. File system extracted via UART shell. |
