An HTTP request smuggling in web application in ASUS ROG Rapture GT-AX11000, RT-AX3000, RT-AX55, RT-AX56U, RT-AX56UV2, 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-AX56UV2, 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.

An HTTP response splitting attack in web application in ASUS RT-AX88U before v3.0.0.4.388.20558 allows an attacker to craft a specific URL that if an authenticated victim visits it, the URL will give access to the cloud storage of the attacker.

ASUS RT-AX88U's httpd is subject to an unauthenticated DoS condition. A remote attacker can send a specially crafted request to a device which contains a specific user agent, causing the httpd binary to crash during a string comparison performed within web.c, resulting in a DoS condition.

ASUS RT-AX88U's httpd is subject to an unauthenticated DoS condition. A remote attacker can send a specially crafted request to the device which causes the httpd binary to crash within the "dojsondecode()" function of ej.c, resulting in a DoS condition.

A stored cross-site scripting (XSS) issue was discovered within the Custom User Icons functionality of ASUS RT-AX88U running firmware versions 3.0.0.4.388.23110 and prior.  After a remote attacker logging in device with regular user privilege, the remote attacker can perform a Stored Cross-site Scripting (XSS) attack by uploading image which containing JavaScript code.

ASUS router RT-AX88U has a vulnerability of using externally controllable format strings within its Advanced Open VPN function. An authenticated remote attacker can exploit the exported OpenVPN configuration to execute an externally-controlled format string attack, resulting in sensitivity information leakage, or forcing the device to reset and permanent denial of service.

ASUS RT-AX88U has insufficient filtering for special characters in the HTTP header parameter. A remote attacker with general user privilege can exploit this vulnerability to inject JavaScript and perform Stored Cross-Site Scripting (XSS) attacks.

ASUS RT-AX88U has a Format String vulnerability, which allows an unauthenticated remote attacker to write to arbitrary memory address and perform remote arbitrary code execution, arbitrary system operation or disrupt service.

An issue was discovered in ASUSWRT 3.0.0.4.384.20308. An unauthenticated user can request /updateapplist.asp to see if a USB device is attached to the router and if there are apps installed on the router.

An issue was discovered in ASUSWRT 3.0.0.4.384.20308. An unauthenticated user can trigger a DoS of the httpd service via the /APPInstallation.asp?= URI.

An issue was discovered in ASUSWRT 3.0.0.4.384.20308. When processing the /startapply.htm POST data, there is a command injection issue via shell metacharacters in the fbemail parameter. By using this issue, an attacker can control the router and get shell.

ASUS RT-A88U 3.0.0.4.38645898 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.

Buffer Overflow vulnerability in ASUS router RT-AX88U with firmware versions v3.0.0.4.38824198 allows a remote attacker to execute arbitrary code via the connectionstatemachine due to improper length validation for the cookie field.
