This relates to handle_request in router/httpd/httpd.c and auth_check in web_hook.o. An attacker-supplied value of '\\0' matches the device's default value of '\\0' in some situations. Note: All versions of Lyra Mini and earlier which are unsupported (End-of-Life, EOL) are also affected by this vulnerability, Consumers can mitigate this vulnerability by disabling the remote access features from WAN.","published":"2021-05-06T15:15:07.973","modified":"2026-06-17T03:52:42.307","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.99393,"percentile":0.99939,"asOf":"2026-09-05"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"EXPLOIT","url":"https://github.com/atredispartners/advisories/blob/master/ATREDIS-2020-0010.md"},{"type":"WEB","url":"https://www.asus.com/Networking-IoT-Servers/WiFi-Routers/ASUS-Gaming-Routers/RT-AC2900/HelpDesk_BIOS/"},{"type":"WEB","url":"https://www.asus.com/us/supportonly/lyra%20mini/helpdesk_bios/"},{"type":"EXPLOIT","url":"https://www.atredis.com/blog/2021/4/30/asus-authentication-bypass"},{"type":"EXPLOIT","url":"https://github.com/atredispartners/advisories/blob/master/ATREDIS-2020-0010.md"},{"type":"WEB","url":"https://www.asus.com/Networking-IoT-Servers/WiFi-Routers/ASUS-Gaming-Routers/RT-AC2900/HelpDesk_BIOS/"},{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2021-32030"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-06-17T03:52:42.307"}}
