A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted goform/setUsbUnload request. This occurs because the \"formsetUsbUnload\" function executes a dosystemCmd function with untrusted input.","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-78"],"in_kev":true,"kev_date_added":"2021-11-03","kev_ransomware":false,"epss_score":0.0851,"epss_percentile":0.95042,"cap_rule_version":"0.1.1","stage":"INITIAL_ACCESS","req_access":"NONE","req_vector":"NETWORK","req_user_interaction":false,"grant_access":"USER","caps":["CODE_EXEC"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-09-18T08:53:24.036797+00:00","first_seen":"2018-10-30T18:29:00.580000+00:00","kev_first_seen":"2021-11-03T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["tenda"],"products":["ac10","ac10_firmware","ac7","ac7_firmware","ac9","ac9_firmware"],"affected":[{"vendor":"tenda","product":"ac10_firmware","ranges":["≤ 15.03.06.23_cn"]},{"vendor":"tenda","product":"ac7_firmware","ranges":["≤ 15.03.06.44_cn"]},{"vendor":"tenda","product":"ac9_firmware","ranges":["≤ 15.03.05.19\\(6318\\)_cn"]}]}
