https://notcve.org/view.php?id=CVE-2019-15803
An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. Through an undocumented sequence of keypresses, undocumented functionality is triggered. A diagnostics shell is triggered via CTRL-ALT-t, which prompts for the password returned by fds_sys_passDebugPasswd_ret(). The firmware contains access control checks that determine if remote users are allowed to access this functionality. The function that performs this check (fds_sys_remoteDebugEnable_ret in libfds.so) always return TRUE with no actual checks performed. • https://jasper.la/exploring-zyxel-gs1900-firmware-with-ghidra.html https://www.zyxel.com/support/gs1900-switch-vulnerabilities.shtml • CWE-287: Improper Authentication •

An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. By sending a signal to the CLI process, undocumented functionality is triggered. Specifically, a menu can be triggered by sending the SIGQUIT signal to the CLI application (e.g., through CTRL+\ via SSH). The access control check for this menu does work and prohibits accessing the menu, which contains "Password recovery for specific user" options. The menu is believed to be accessible using a serial console. • https://jasper.la/exploring-zyxel-gs1900-firmware-with-ghidra.html https://www.zyxel.com/support/gs1900-switch-vulnerabilities.shtml •
