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.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","base_score":9.8,"base_severity":"CRITICAL","attack_vector":"NETWORK","privileges_req":"NONE","user_interaction":"NONE","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-287"],"in_kev":true,"kev_date_added":"2025-06-02","kev_ransomware":false,"epss_score":0.99393,"epss_percentile":0.9994,"cap_rule_version":"0.1.1","stage":"INITIAL_ACCESS","req_access":"NONE","req_vector":"NETWORK","req_user_interaction":false,"grant_access":"USER","caps":["AUTH_BYPASS","CODE_EXEC"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-09-18T09:41:33.892865+00:00","first_seen":"2021-05-06T15:15:07.973000+00:00","kev_first_seen":"2025-06-02T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["asus"],"products":["gt-ac2900","gt-ac2900_firmware","lyra_mini","lyra_mini_firmware"],"affected":[{"vendor":"asus","product":"gt-ac2900_firmware","ranges":["< 3.0.0.4.386.42643"]},{"vendor":"asus","product":"lyra_mini_firmware","ranges":["< 3.0.0.4.384.46630"]}]}
