Firmware issues which are not armless

ASUS has released new firmware for several router models to address security vulnerabilities, including critical ones like CVE-2022-26376 and CVE-2018-1160, which can lead to denial-of-service attacks and code execution.

The company is telling its customers to update their devices immediately or restrict WAN access until the devices are secured, urging them to create strong passwords and follow security measures.

The first issue is a critical memory corruption weakness in the Asuswrt firmware for Asus routers that could let attackers trigger denial-of-services states or gain code execution. The other critical patch is for an almost five-year-old CVE-2018-1160 bug caused by an out-of-bounds write Netatalk weakness that can also be exploited to gain arbitrary code execution on unpatched devices.

ASUS warned: "Please note, if you choose not to install this new firmware version, we strongly recommend disabling services accessible from the WAN side to avoid potential unwanted intrusions. These services include remote access from WAN, port forwarding, DDNS, VPN server, DMZ, port trigger. We strongly encourage you to periodically audit both your equipment and your security procedures, as this will ensure that you will be better protected."

The list of impacted devices includes the following models: GT6, GT-AXE16000, GT-AX11000 PRO, GT-AX6000, GT-AX11000, GS-AX5400, GS-AX3000, XT9, XT8, XT8 V2, RT-AX86U PRO, RT-AX86U, RT-AX86S, RT-AX82U, RT-AX58U, RT-AX3000, TUF-AX6000, and TUF-AX5400.
