| Zyxel VMG5313-B30B router on firmware 5.13(ABCJ.6)b3_1127, and possibly older versions of firmware are affected by insecure permissions which allows regular and other users to create new users with elevated privileges. This is done by changing "FirstIndex" field in JSON that is POST-ed during account creation. Similar may also be possible with account deletion. | |||||
| CVE-2020-24354 | 1 Zyxel | 2 Vmg5313-b30b, Vmg5313-b30b Firmware | 2020-09-04 | 6.5 MEDIUM | 8.8 HIGH |

| CVE-2018-14893 | 1 Zyxel | 2 Nsa325 V2, Nsa325 V2 Firmware | 2020-08-24 | 9.0 HIGH | 8.8 HIGH |
| A system command injection vulnerability in zyshclient in ZyXEL NSA325 V2 version 4.81 allows attackers to execute system commands via the web application API. | |||||
| 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. | |||||
| CVE-2019-12583 | 1 Zyxel | 28 Uag2100, Uag2100 Firmware, Uag4100 and 25 more | 2020-08-24 | 6.4 MEDIUM | 9.1 CRITICAL |
| Missing Access Control in the "Free Time" component of several Zyxel UAG, USG, and ZyWall devices allows a remote attacker to generate guest accounts by directly accessing the account generator. This can lead to unauthorised network access or Denial of Service. | |||||
| CVE-2019-17354 | 1 Zyxel | 2 Nbg-418n V2, Nbg-418n V2 Firmware | 2020-08-24 | 7.5 HIGH | 9.4 CRITICAL |
| wan.htm page on Zyxel NBG-418N v2 with firmware version V1.00(AARP.9)C0 can be accessed directly without authentication, which can lead to disclosure of information about the WAN, and can also be leveraged by an attacker to modify data fields of the page. | |||||
| CVE-2019-10631 | 1 Zyxel | 2 Nas326, Nas326 Firmware | 2020-08-24 | 6.5 MEDIUM | 8.8 HIGH |
| Shell Metacharacter Injection in the package installer on Zyxel NAS 326 version 5.21 and below allows an authenticated attacker to execute arbitrary code via multiple different requests. | |||||
| CVE-2019-15815 | 1 Zyxel | 2 2.00\(abbx.3\), P-1302-t10d | 2020-08-24 | 4.0 MEDIUM | 6.5 MEDIUM |
| ZyXEL P-1302-T10D v3 devices with firmware version 2.00(ABBX.3) and earlier do not properly enforce access control and could allow an unauthorized user to access certain pages that require admin privileges. | |||||
| CVE-2019-15803 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2020-08-24 | 6.4 MEDIUM | 9.1 CRITICAL |
| 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. The diagnostics menu allows for reading/writing arbitrary registers and various other configuration parameters which are believed to be related to the network interface chips. | |||||
| CVE-2019-10630 | 1 Zyxel | 2 Nas326, Nas326 Firmware | 2020-08-24 | 4.0 MEDIUM | 8.8 HIGH |
| A plaintext password vulnerability in the Zyxel NAS 326 through 5.21 allows an elevated privileged user to get the admin password of the device. | |||||
| CVE-2019-15800 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2020-08-24 | 10.0 HIGH | 9.8 CRITICAL |
| 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 on the switches. (Note that these functions are currently not called in this version of the firmware, however an attacker could use other vulnerabilities to finally use these vulnerabilities to gain code execution.) | |||||
