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.

A memory corruption vulnerability exists in the httpd unescape functionality of Asuswrt prior to 3.0.0.4.38648706 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-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.

ASUS RT-AX86U router firmware below version under 9.0.0.4386 has a buffer overflow in the blockingrequest.cgi function of the httpd module that can cause code execution when an attacker constructs malicious data.
