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.

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-AC86U Traffic Analyzer - Apps analysis function has insufficient filtering of special character. A remote attacker with regular user privilege can exploit this vulnerability to perform command injection attack to execute arbitrary commands, disrupt system or terminate services.

ASUS RT-AC86U Traffic Analyzer - Statistic function has insufficient filtering of special character. A remote attacker with regular user privilege can exploit this vulnerability to perform command injection attack to execute arbitrary commands, disrupt system or terminate services.

ASUS RT-AC86U unused Traffic Analyzer legacy Statistic function has insufficient filtering of special character. A remote attacker with regular user privilege can exploit this vulnerability to perform command injection attack to execute arbitrary commands, disrupt system or terminate services.

ASUS RT-AC86U AiProtection security- related function has insufficient filtering of special character. A remote attacker with regular user privilege can exploit this vulnerability to perform command injection attack to execute arbitrary commands, disrupt system or terminate services.

ASUS RT-AC86U Adaptive QoS - Web History function has insufficient filtering of special character. A remote attacker with regular user privilege can exploit this vulnerability to perform command injection attack to execute arbitrary commands, disrupt system or terminate services.

It is identified a format string vulnerability in ASUS RT-AX56U V2 & RT-AC86U. This vulnerability is caused by lacking validation for a specific value when calling cm_processChangedConfigMsg in ccm_processREQ_CHANGED_CONFIG function in AiMesh system. An unauthenticated remote attacker can exploit this vulnerability without privilege to perform remote arbitrary code execution, arbitrary system operation or disrupt service. This issue affects RT-AX56U V2: 3.0.0.4.386_50460; RT-AC86U: 3.0.0.4_386_51529.

It is identified a format string vulnerability in ASUS RT-AX56U V2 & RT-AC86U. This vulnerability is caused by directly using input as a format string when calling syslog in logmessage_normal function, in the do_detwan_cgi module of httpd. A remote attacker with administrator privilege can exploit this vulnerability to perform remote arbitrary code execution, arbitrary system operation or disrupt service. This issue affects RT-AX56U V2: 3.0.0.4.386_50460; RT-AC86U: 3.0.0.4_386_51529.

ASUS RT-AC86U’s specific cgi function has a stack-based buffer overflow vulnerability due to insufficient validation for network packet header length. A remote attacker with administrator privileges can exploit this vulnerability to execute arbitrary system commands, disrupt system or terminate service.

ASUS RT-AC86U does not filter special characters for parameters in specific web URLs. A remote attacker with normal user privileges can exploit this vulnerability to perform command injection attack to execute arbitrary system commands, disrupt system or terminate service.

ASUS RT-AC86U’s LPD service has insufficient filtering for special characters in the user request, which allows an unauthenticated LAN attacker to perform command injection attack, execute arbitrary commands and disrupt or terminate service.

ASUS RT-AC56U’s configuration function has a heap-based buffer overflow vulnerability due to insufficient validation for the decryption parameter length, which allows an unauthenticated LAN attacker to execute arbitrary code, perform arbitrary operations and disrupt service.

ASUS RT-AC86U has improper user request handling, which allows an unauthenticated LAN attacker to cause a denial of service by sending particular request a server-to-client reply attempt.
