ASUS OVPN RCE

ASUS routers supporting custom OpenVPN profiles are vulnerable to a code execution vulnerability. An authenticated and remote attacker can execute arbitrary operating system commands by uploading a crafted OVPN profile. Known affected routers include ASUS ExpertWiFi, ASUS RT-AX55, ASUS RT-AX58U, ASUS RT-AC67U, ASUS RT-AC68R, ASUS RT-AC68U, ASUS RT-AX86, ASUS RT-AC86U, ASUS RT-AX88U, and ASUS RT-AX3000.

On ASUS RT-AX55 3.0.0.4.386.51598 devices, authenticated attackers can perform OS command injection via the /start_apply.htm qos_bw_rulelist parameter. NOTE: for the similar "token-generated module" issue, see CVE-2023-41345; for the similar "token-refresh module" issue, see CVE-2023-41346; for the similar "check token module" issue, see CVE-2023-41347; and for the similar "code-authentication module" issue, see CVE-2023-41348.

A memory corruption vulnerability exists in the httpd unescape functionality of Asuswrt prior to 3.0.0.4.386_48706 and Asuswrt-Merlin New Gen prior to 386.7.. A specially-crafted HTTP request can lead to memory corruption. An attacker can send a network request to trigger this vulnerability.

ASUS RT-AX55、RT-AX56U_V2 - Format String - 3

It is identified a format string vulnerability in ASUS RT-AX56U V2’s iperf client function API. This vulnerability is caused by lacking validation for a specific value within its set_iperf3_cli.cgi module. A remote attacker with administrator privilege can exploit this vulnerability to perform remote arbitrary code execution, arbitrary system operation or disrupt service.

ASUS RT-AX55、RT-AX56U_V2、RT-AC86U - Format String - 2

It is identified a format string vulnerability in ASUS RT-AX56U V2’s General function API. This vulnerability is caused by lacking validation for a specific value within its apply.cgi module. A remote attacker with administrator privilege can exploit this vulnerability to perform remote arbitrary code execution, arbitrary system operation or disrupt service.

ASUS RT-AX55、RT-AX56U_V2 - Format String - 1

It is identified a format string vulnerability in ASUS RT-AX56U V2. This vulnerability is caused by lacking validation for a specific value within its set_iperf3_svr.cgi module. A remote attacker with administrator privilege can exploit this vulnerability to perform remote arbitrary code execution, arbitrary system operation or disrupt service.

ASUS RT-A88U 3.0.0.4.386_45898 is vulnerable to Cross Site Scripting (XSS). The ASUS router admin panel does not sanitize the WiFI logs correctly, if an attacker was able to change the SSID of the router with a custom payload, they could achieve stored XSS on the device.

An HTTP request smuggling in web application in ASUS ROG Rapture GT-AX11000, RT-AX3000, RT-AX55, RT-AX56U, RT-AX56U_V2, RT-AX58U, RT-AX82U, RT-AX82U GUNDAM EDITION, RT-AX86 Series(RT-AX86U/RT-AX86S), RT-AX86U ZAKU II EDITION, RT-AX88U, RT-AX92U, TUF Gaming AX3000, TUF Gaming AX5400 (TUF-AX5400), ASUS ZenWiFi XD6, ASUS ZenWiFi AX (XT8) before 3.0.0.4.386.45898, and RT-AX68U before 3.0.0.4.386.45911, allows a remote unauthenticated attacker to DoS via sending a specially crafted HTTP packet.

A brute-force protection bypass in CAPTCHA protection in ASUS ROG Rapture GT-AX11000, RT-AX3000, RT-AX55, RT-AX56U, RT-AX56U_V2, RT-AX58U, RT-AX82U, RT-AX82U GUNDAM EDITION, RT-AX86 Series(RT-AX86U/RT-AX86S), RT-AX86U ZAKU II EDITION, RT-AX88U, RT-AX92U, TUF Gaming AX3000, TUF Gaming AX5400 (TUF-AX5400), ASUS ZenWiFi XD6, ASUS ZenWiFi AX (XT8) before 3.0.0.4.386.45898, and RT-AX68U before 3.0.0.4.386.45911, allows a remote attacker to attempt any number of login attempts via sending a specific HTTP request.

In ASUS RT-AX3000, ZenWiFi AX (XT8), RT-AX88U, and other ASUS routers with firmware < 3.0.0.4.386.42095 or < 9.0.0.4.386.41994, when IPv6 is used, a routing loop can occur that generates excessive network traffic between an affected device and its upstream ISP's router. This occurs when a link prefix route points to a point-to-point link, a destination IPv6 address belongs to the prefix and is not a local IPv6 address, and a router advertisement is received with at least one global unique IPv6 prefix for which the on-link flag is set.

ASUS GT-AXE11000, RT-AX3000, RT-AX55, RT-AX58U, TUF-AX3000 - Improper Authentication

ASUS routers Wi-Fi protected access protocol (WPA2 and WPA3-SAE) has improper control of Interaction frequency vulnerability, an unauthenticated attacker can remotely disconnect other users' connections by sending specially crafted SAE authentication frames.
