| CVE-2019-15804 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2020-08-24 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
