CVE-2021-35032 [MEDIUM] CWE-78 CVE-2021-35032: A vulnerability in the 'libsal.so' of the Zyxel GS1900 series firmware version 2.60 could allow an a 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-2021-35030 [LOW] CWE-79 CVE-2021-35030: A vulnerability was found in the CGI program in Zyxel GS1900-8 firmware version V2.60, that did not 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.

CVE-2019-15800 [CRITICAL] CWE-78 CVE-2019-15800: An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. Due to lack of An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. Due to lack of input validation in the cmd_sys_traceroute_exec(), cmd_sys_arp_clear(), and cmd_sys_ping_exec() functions in the libclicmd.so library contained in the firmware, an attacker could leverage these functions to call system() and execute arbitrary commands

CVE-2019-15803 [CRITICAL] CWE-287 CVE-2019-15803: An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. Through an undo 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 det

CVE-2019-15804 [HIGH] CVE-2019-15804: An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. By sending a si 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

CVE-2019-15799 [HIGH] CWE-269 CVE-2019-15799: An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. User accounts c An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. User accounts created through the web interface of the device, when given non-admin level privileges, have the same level of privileged access as administrators when connecting to the device via SSH (while their permissions via the web interface are in fact restricted

CVE-2019-15801 [HIGH] CWE-798 CVE-2019-15801: An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. The firmware im 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 elsewhere in the firmware, these passwords can be decrypted. This is related to f

CVE-2019-15802 [MEDIUM] CWE-798 CVE-2019-15802: An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. The firmware ha 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 all passwords using AES256 in CBC mode. With the parameters known, all
