ASUS Product Security Advisory

During routine security maintenance, our technical team discovered an error in the configuration of our server settings file, which could potentially cause an interruption in network connectivity on part of the routers.

Our technical team has urgently addressed the server issue and impacted routers should return to normal operation. If your device was affected, we recommend the following:

1. Manually reboot your router.
2. If rebooting does not resolve the issue, please save the settings file, perform a hard reset (factory default), and then re-upload the settings file (follow the directions in the https://www.asus.com/support/FAQ/1050464 )
3. If you cannot access the user interface to save settings or perform a reset, you can press the RESET button for about 5-10 seconds until the power LED indicator on the router starts to blink, which means the reset is completed. https://www.asus.com/support/FAQ/1000925/#m2

If there are any further developments around this issue, we will immediately update our users.

We deeply apologize for any inconvenience this incident may have caused and are committed to preventing such an incident from happening again.

Severity: Medium

ASUS is aware of newly discovered industry-wide WiFi protocol vulnerabilities that affect every brand of WiFi router. The vulnerabilities are known as Fragmentation and Aggregation Attacks (commonly called Frag Attacks). WiFi devices using the WEP, WPA, WPA2 or WPA3 encryption schemes are affected. FragAttacks can be used to silently steal data, and they can also lead to other exploits.
Please note that an attacker needs to be connected to your WiFi network in order to exploit these vulnerabilities, so they need to be within WiFi signal range and know your WiFi password.

ASUS is working round the clock to release firmware fixes for these vulnerabilities.
Please check the list of router models below for links to updated firmware.

If firmware is not yet available for your product, please follow these workarounds to protect your network.

Security advisory for DNSpooq

CVE: CVE-2020-25681, CVE-2020-25782, CVE-2020-25683, CVE-2020-25684, CVE-2020-25685, CVE-2020-25686, CVE-2020-25687

Severity: Medium

Abstract

This quick-patch beta firmware was released on February 2, 2021. The first model-specific regular firmware update has just been released, and other models are scheduled to follow in the near future. The beta firmware requires users to perform a manual update.

Products from over 40 companies, including ASUS routers, are affected by DNSpooq.

There are two sets of vulnerabilities.

• Buffer-overflow vulnerabilities: CVE-2020-25681, CVE-2020-25682, CVE-2020-25683, CVE-2020-25687
• DNS cache-poisoning vulnerabilities: CVE-2020-25684, CVE-2020-25685, CVE-2020-25686

No ASUS routers are affected by CVE-2020-25681, CVE-2020-25682, CVE-2020-25683, CVE-2020-25687, because these vulnerabilities only affect DNSSEC.

ASUS routers are only affected by DNS cache-poisoning vulnerabilities, with medium severity. All these vulnerabilities can be fixed by updating to the new firmware.
DNS cache poisoning can potentially allow a remote-code execution that would impact the security of many brands of home router and other networking equipment.

ASUS is aware of the vulnerability listed below. We take your security seriously and are working diligently to provide a software update for the affected ZenFone/ZenPad models. Please update your ZenFone/ZenPad to the latest software version as soon as it becomes available. In the meantime, we highly recommended using ASUS Mobile Manager or installing another reliable third-party security app to further secure your devices.

Possible vulnerability:
• A malicious app can get a bug report.
• A malicious app can take a screenshot (with a screenshot animation).
• Arbitrary apps can be installed remotely over the internet and can also be uninstalled after being run.
• Commands can be executed as the system user.

The following are some security precautions recommended for all users:
(1) Ensure your operating system and software up to date with the latest version, which you can find on the ASUS website (www.asus.com). Using the search tool located on the top right hand of the ASUS website, search for your device model, and then follow this path: Support > Driver & Utility > Driver & Tools > BIOS & Firmware. Here you can double check if the latest version is the same on your device or you can choose to download it in the event your device did not automatically update.
(2) Do not download any apps outside of Google Play.
(3) Uninstall all apps previously downloaded from non-Google Play sources.
(4) Install ASUS Mobile Manager or a reliable third-party security app to strengthen the security of your devices and applications.

Talos Intelligence recently discovered that VPNFilter is targeting more makes and models than initial release, and the following ASUS routers may be potential targets:
RT-AC66U
RT-N10 (EOL)
RT-N10E (EOL)
RT-N10U (EOL)
RT-N56U (EOL)
RT-N66U

To help owners of these routers take necessary precautions, we compiled a security checklist:
(1) Reset the device to factory default: Hold the Reset button in the rear for at least five seconds until the power LED starts blinking.
(2) Update all devices to the latest firmware.
(3) Ensure default admin password had been changed to a more secure one.
(4) Disable Remote Management (disabled by default, can only be enabled via Advanced Settings).
(5) Enable the URL filter in the Advanced Settings -> Firewall. Set the Filter table type as Black List. Add the "photobucket" and "toknowall" in the URL filter list.

For any users with the EOL models listed above, we strongly advise upgrading to a router with AiProtection. A wide selection of ASUS and ROG routers offer AiProtection powered by Trend Micro™. Anytime a threat is detected, the connection between your device and the malicious server is blocked before any personal data is compromised. The list of malicious servers is constantly updated by syncing with the Trend Micro cloud database automatically, to ensure your network environment is secure around the clock.

Vulnerability: CVE-2018-5999, CVE-2018-6000

ASUS and ROG router products affected are shown in a list below.

This vulnerability bypasses any user/password changes made by the owner.
Possible changes to router settings:

• Port number changes
• VPN account & password changes
• DDNS changes
• The UI language has changed

Solution:
Please immediately update your ASUS and ROG router to the latest firmware available.
If a firmware update cannot be made the mitigations listed below should be applied, however it’s strongly advised the user updates the firmware at the earliest opportunity:

• Disable SSH / Telnet
• Disable VPN (available on limited models)
• Enable AiProtection (available on limited models)
• Change login ID & password again. The password should be at least 8 characters using a mix of letters, numbers and special symbols.

ASUS is working closely with chipset suppliers to resolve the vulnerability in the WPA2 security protocol, which affects some but not all ASUS products (check the list below). KRACK can exploit the vulnerability only under certain conditions highlighted in the previous update. Your network configuration is more secure when under these conditions:

(1) Routers and gateways working in their default mode (Router Mode) and AP Mode.
(2) Range extenders working in AP Mode.
(3) When Powerline adapters and switch products are used.

ASUS is working actively towards a solution, and will continue to post software updates. Find out more: https://www.asus.com/support/

ASUS is aware of the recent WPA2 vulnerability issue. We take your security and privacy seriously and are currently working towards a full solution as quickly as possible. In the meantime, we want to help clarify the severity of the potential threat, and let our valued customers know the appropriate steps to take in order to avoid or lessen the threat of being compromised.

Your devices are only vulnerable if an attacker is in physical proximity to your wireless network and is able to gain access to it. This exploit cannot steal your banking information, passwords, or other data on a secured connection that utilizes proper end-to-end encryption. However, an attacker could capture and read this information on an unsecured connection via an exploited WiFi network. Depending on the network configuration, it is also possible for the attacker to redirect network traffic, send invalid data to devices or even inject malware into the network.

We are feverishly working with chipset suppliers to resolve this vulnerability and will release patched firmware for affected routers in the near future. Before this patched firmware is released, here are a few cautions all users should take:

(1) Avoid public Wi-Fi and Hotspots until the routers and your devices are updated. Use cellular network connections if possible.
(2) Only connect to secured services that you trust or have been verified. Web pages that use HTTPS or another secure connection will include HTTPS in the URL. If the connection is secured using TLS 1.2 your activities with that service is safe for now.
(3) Keep your operating system and antivirus software up-to-date. Microsoft recently updated Windows to fix this exploit on their latest operating systems. Google and Apple are following suit shortly.
(4) When in doubt, be safe and use your cellular network or a wired connection (Ethernet) to access the internet. This exploit only affects 802.11 traffic between a Wi-Fi router and a connected device on an exploited WiFi connection.
