{"schema":"threatline.record/2","record":{"id":"CVE-2020-24363","aliases":[],"summary":"TP-link TL-WA855RE Missing Authentication for Critical Function Vulnerability","details":"TP-link TL-WA855RE contains a missing authentication for critical function vulnerability. This vulnerability could allow an unauthenticated attacker (on the same network) to submit a TDDP_RESET POST request for a factory reset and reboot. The attacker can then obtain incorrect access control by setting a new administrative password. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.","categories":["Network & edge"],"product":"TL-WA855RE","vendor":"TP-Link","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2020-24363","source_modified_at":"2025-10-21T23:35:37.336Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"n/a","vendor":"n/a","versions":[{"status":"affected","version":"n/a"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":true,"date_added":"2025-09-02","due_date":"2025-09-23","required_action":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","ransomware_campaign_use":"Unknown"},"epss":{"probability":0.22187,"percentile":0.97674,"score_date":"2026-10-23"},"published_at":"2020-08-31T15:49:15.000Z","modified_at":"2025-10-21T23:35:37.336Z","provenance":[{"source":"CISA KEV","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T17:00:09.9001Z"},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2020-24363","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2025-10-21T23:35:37.336Z"},{"source":"Exploit-DB","url":"https://www.exploit-db.com/exploits/49092","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2020-11-23"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2020-24363","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CISA KEV","CVE List","Exploit-DB","EPSS"],"references":[{"url":"https://www.tp-link.com/us/home-networking/range-extender/tl-wa855re/#overview","source":"CISA KEV"},{"url":"https://www.tp-link.com/us/support/download/tl-wa855re/#FAQs","source":"CISA KEV"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-24363","source":"CISA KEV"},{"source":"CVE List","url":"https://www.tp-link.com/us/support/download/tl-wa855re/#Firmware","tags":["x_refsource_MISC","x_transferred"]},{"source":"CVE List","url":"https://pastebin.com/VjHM4UiA","tags":["x_refsource_MISC","x_transferred"]},{"source":"CVE List","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2020-24363","tags":["government-resource"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"active","automatable":"no","technical_impact":"total","assessed_at":"2025-08-30T03:55:36.795660Z"},"exploits":[{"source":"Exploit-DB","kind":"Webapps exploit","name":"TP-Link TL-WA855RE V5_200415 - Device Reset Auth Bypass","url":"https://www.exploit-db.com/exploits/49092","date":"2020-11-23","added":"2020-11-23","verified":false}],"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2025-10-21T23:35:37.336Z","content_hash":"58ddda06af67bf0a14a8c6ec2d9ef28e06f32c43387a18dfc5b468b950e53d2e"}}
