Certain ASUS router models have authentication bypass vulnerability, allowing unauthenticated remote attackers to log in the device.

Certain models of ASUS routers have buffer overflow vulnerabilities, allowing remote attackers with administrative privileges to execute arbitrary commands on the device.

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.

Directory Traversal vulnerability in Cloud Disk in ASUS RT-AC68U router firmware version before 3.0.0.4.386.41634 allows remote attackers to write arbitrary files via improper sanitation on the target for COPY and MOVE operations.

SQL injection vulnerability in Cloud Disk in ASUS RT-AC68U router firmware version before 3.0.0.4.386.41634 allows remote attackers to view sensitive information via /etc/shadow.

Incorrect Access Control issue discoverd in Cloud Disk in ASUS RT-AC68U router firmware version before 3.0.0.4.386.41634 allows remote attackers to write arbitrary files via improper sanitation on the source for COPY and MOVE operations.

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.

ASUS AC68U <=3.0.0.4.385.20852 is affected by a buffer overflow in blocking.cgi, which may cause a denial of service (DoS).

Asus RT-AC68U <3.0.0.4.385.20633 and RT-AC5300 <3.0.0.4.384.82072 are affected by a buffer overflow in blocking_request.cgi.

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.
