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+\… | ||
| CVE-2019-15801 | Hig | 0.49 | 7.5 | 0.01 | Nov 14, 2019 | An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. The firmware image contains encrypted passwords that are used to authenticate users wishing to access a diagnostics or password-recovery menu. Using the hardcoded cryptographic key found… | ||
| CVE-2021-35031 | Med | 0.44 | 6.8 | 0.00 | Dec 28, 2021 | A vulnerability in the TFTP client of Zyxel GS1900 series firmware, XGS1210 series firmware, and XGS1250 series firmware, which could allow an authenticated LAN user to execute arbitrary OS commands via the GUI of the vulnerable device. | ||
| CVE-2021-35032 | Med | 0.42 | 6.4 | 0.00 | Dec 28, 2021 | A vulnerability in the 'libsal.so' of the Zyxel GS1900 series firmware version 2.60 could allow an authenticated local user to execute arbitrary OS commands via a crafted function call. | ||
| CVE-2019-15802 | Med | 0.38 | 5.9 | 0.01 | Nov 14, 2019 | An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. The firmware hashes and encrypts passwords using a hardcoded cryptographic key in sal_util_str_encrypt() in libsal.so.0.0. The parameters (salt, IV, and key data) are used to encrypt and decrypt… | ||
| CVE-2021-35030 | Low | 0.23 | 3.5 | 0.00 | Jul 26, 2021 | A vulnerability was found in the CGI program in Zyxel GS1900-8 firmware version V2.60, that did not properly sterilize packet contents and could allow an authenticated, local user to perform a cross-site scripting (XSS) attack via a crafted LLDP packet. |
