| CVE-2021-20163 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 4.0 MEDIUM | 4.9 MEDIUM |
| Trendnet AC2600 TEW-827DRU version 2.08B01 leaks information via the ftp web page. Usernames and passwords for all ftp users are revealed in plaintext on the ftpserver.asp page. | |||||
| CVE-2021-20156 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 4.0 MEDIUM | 6.5 MEDIUM |
| Trendnet AC2600 TEW-827DRU version 2.08B01 contains an improper access control configuration that could allow for a malicious firmware update. It is possible to manually install firmware that may be malicious in nature as there does not appear to be any signature validation done to determine if it is from a known and trusted source. This includes firmware updates that are done via the automated "check for updates" in the admin interface. If an attacker is able to masquerade as the update server, the device will not verify that the firmware updates downloaded are legitimate. | |||||
| CVE-2021-20162 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 4.0 MEDIUM | 4.9 MEDIUM |
| Trendnet AC2600 TEW-827DRU version 2.08B01 stores credentials in plaintext. Usernames and passwords are stored in plaintext in the config files on the device. For example, /etc/config/cameo contains the admin password in plaintext. | |||||
| CVE-2021-20161 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 7.2 HIGH | 6.8 MEDIUM |
| Trendnet AC2600 TEW-827DRU version 2.08B01 does not have sufficient protections for the UART functionality. A malicious actor with physical access to the device is able to connect to the UART port via a serial connection. No username or password is required and the user is given a root shell with full control of the device. | |||||
| CVE-2021-20158 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| Trendnet AC2600 TEW-827DRU version 2.08B01 contains an authentication bypass vulnerability. It is possible for an unauthenticated, malicous actor to force the change of the admin password due to a hidden administrative command. | |||||
| CVE-2021-20164 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 4.0 MEDIUM | 4.9 MEDIUM |
| Trendnet AC2600 TEW-827DRU version 2.08B01 improperly discloses credentials for the smb functionality of the device. Usernames and passwords for all smb users are revealed in plaintext on the smbserver.asp page. | |||||
| CVE-2021-20151 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 7.5 HIGH | 10.0 CRITICAL |
| Trendnet AC2600 TEW-827DRU version 2.08B01 contains a flaw in the session management for the device. The router's management software manages web sessions based on IP address rather than verifying client cookies/session tokens/etc. This allows an attacker (whether from a different computer, different web browser on the same machine, etc.) to take over an existing session. This does require the attacker to be able to spoof or take over original IP address of the original user's session. | |||||
| CVE-2021-20160 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 9.0 HIGH | 8.8 HIGH |
| Trendnet AC2600 TEW-827DRU version 2.08B01 contains a command injection vulnerability in the smb functionality of the device. The username parameter used when configuring smb functionality for the device is vulnerable to command injection as root. | |||||
| CVE-2021-20154 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 4.3 MEDIUM | 7.5 HIGH |
| Trendnet AC2600 TEW-827DRU version 2.08B01 contains an security flaw in the web interface. HTTPS is not enabled on the device by default. This results in cleartext transmission of sensitive information such as passwords. | |||||
| CVE-2021-20152 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 5.8 MEDIUM | 6.5 MEDIUM |
| Trendnet AC2600 TEW-827DRU version 2.08B01 lacks proper authentication to the bittorrent functionality. If enabled, anyone is able to visit and modify settings and files via the Bittorent web client by visiting: http://192.168.10.1:9091/transmission/web/ | |||||
| CVE-2021-20149 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| Trendnet AC2600 TEW-827DRU version 2.08B01 does not have sufficient access controls for the WAN interface. The default iptables ruleset for governing access to services on the device only apply to IPv4. All services running on the devices are accessible via the WAN interface via IPv6 by default. | |||||
| CVE-2021-20165 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 6.8 MEDIUM | 8.8 HIGH |
| Trendnet AC2600 TEW-827DRU version 2.08B01 does not properly implement csrf protections. Most pages lack proper usage of CSRF protections or mitigations. Additionally, pages that do make use of CSRF tokens are trivially bypassable as the server does not appear to validate them properly (i.e. re-using an old token or finding the token thru some other method is possible). | |||||
| CVE-2021-20155 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| Trendnet AC2600 TEW-827DRU version 2.08B01 makes use of hardcoded credentials. It is possible to backup and restore device configurations via the management web interface. These devices are encrypted using a hardcoded password of "12345678". | |||||
| CVE-2021-20150 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 5.0 MEDIUM | 5.3 MEDIUM |
| Trendnet AC2600 TEW-827DRU version 2.08B01 improperly discloses information via redirection from the setup wizard. Authentication can be bypassed and a user may view information as Admin by manually browsing to the setup wizard and forcing it to redirect to the desired page. | |||||
| CVE-2021-20159 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 9.0 HIGH | 8.8 HIGH |
| Trendnet AC2600 TEW-827DRU version 2.08B01 is vulnerable to command injection. The system log functionality of the firmware allows for command injection as root by supplying a malformed parameter. | |||||
| CVE-2021-20153 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 6.9 MEDIUM | 6.8 MEDIUM |
| Trendnet AC2600 TEW-827DRU version 2.08B01 contains a symlink vulnerability in the bittorrent functionality. If enabled, the bittorrent functionality is vulnerable to a symlink attack that could lead to remote code execution on the device. If an end user inserts a flash drive with a malicious symlink on it that the bittorrent client can write downloads to, then a user is able to download arbitrary files to any desired location on the devices filesystem, which could lead to remote code execution. Example directories vulnerable to this include "config", "downloads", and "torrents", though it should be noted that "downloads" is the only vector that allows for arbitrary files to be downloaded to arbitrary locations. | |||||
| CVE-2021-20157 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 7.8 HIGH | 7.5 HIGH |
| It is possible for an unauthenticated, malicious user to force the device to reboot due to a hidden administrative command. | |||||
| CVE-2020-14080 | 1 Trendnet | 2 Tew-827dru, Tew-827dru Firmware | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| TRENDnet TEW-827DRU devices through 2.06B04 contain a stack-based buffer overflow in the ssi binary. The overflow allows an unauthenticated user to execute arbitrary code by POSTing to apply_sec.cgi via the action ping_test with a sufficiently long ping_ipaddr key. | |||||
