An improper input validation vulnerability leads to device crashes in certain ASUS router models. Refer to the '12/03/2024 ASUS Router Improper Input Validation' section on the ASUS Security Advisory for more information.

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.

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.

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.

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.

A stack overflow vulnerability exists in the httpd service in ASUS RT-AX56U Router Version 3.0.0.4.386.44266. This vulnerability is caused by the strcat function called by "caupload" input handle function allowing the user to enter 0xFFFF bytes into the stack. This vulnerability allows an attacker to execute commands remotely. The vulnerability requires authentication.

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-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 RT-AX56U’s update_json function has a path traversal vulnerability due to insufficient filtering for special characters in the URL parameter. An unauthenticated LAN attacker can overwrite a system file by uploading another file with the same file name, which results in service disruption.
