| 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-2019-15815 | 1 Zyxel | 2 2.00\(abbx.3\), P-1302-t10d | 2024-11-21 | 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-2019-15804 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2024-11-21 | 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-2019-15803 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2024-11-21 | 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-2019-15802 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2024-11-21 | 5.9 Medium |
| 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 previously encrypted passwords can be decrypted. This includes the passwords that are part of configuration backups or otherwise embedded as part of the firmware. | ||||
| CVE-2019-15801 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2024-11-21 | 7.5 High |
| 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 fds_sys_passDebugPasswd_ret() and fds_sys_passRecoveryPasswd_ret() in libfds.so.0.0. | ||||
| CVE-2019-15800 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2024-11-21 | 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.) | ||||
| CVE-2019-15799 | 1 Zyxel | 18 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 15 more | 2024-11-21 | 8.8 High |
| 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). This allows normal users to obtain the administrative password by running the tech-support command via the CLI: this contains the encrypted passwords for all users on the device. As these passwords are encrypted using well-known and static parameters, they can be decrypted and the original passwords (including the administrator password) can be obtained. | ||||
| CVE-2019-13495 | 1 Zyxel | 2 Xgs2210-52hp, Xgs2210-52hp Firmware | 2024-11-21 | 5.4 Medium |
| In firmware version 4.50 of Zyxel XGS2210-52HP, multiple stored cross-site scripting (XSS) issues allows remote authenticated users to inject arbitrary web script via an rpSys.html Name or Location field. | ||||
| CVE-2019-12583 | 1 Zyxel | 28 Uag2100, Uag2100 Firmware, Uag4100 and 25 more | 2024-11-21 | N/A |
| 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-2019-12581 | 1 Zyxel | 18 Uag2100, Uag2100 Firmware, Uag4100 and 15 more | 2024-11-21 | N/A |
| A reflective Cross-site scripting (XSS) vulnerability in the free_time_failed.cgi CGI program in selected Zyxel ZyWall, USG, and UAG devices allows remote attackers to inject arbitrary web script or HTML via the err_msg parameter. | ||||
| CVE-2019-10634 | 1 Zyxel | 2 Nas326, Nas326 Firmware | 2024-11-21 | N/A |
| An XSS vulnerability in the Zyxel NAS 326 version 5.21 and below allows a remote authenticated attacker to inject arbitrary JavaScript or HTML via the user, group, and file-share description fields. | ||||
| CVE-2019-10633 | 1 Zyxel | 2 Nas326, Nas326 Firmware | 2024-11-21 | N/A |
| An eval injection vulnerability in the Python web server routing on the Zyxel NAS 326 version 5.21 and below allows a remote authenticated attacker to execute arbitrary code via the tjp6jp6y4, simZysh, and ck6fup6 APIs. | ||||
