The installation uses the same API key (hardcoded as EONAPI_KEY in include/api_functions.php for API version 2.4.2) by default for all installations, hence allowing an attacker to calculate/guess the admin access token.","provenance":"source","from":"NVD"},"summary":{"text":"EyesOfNetwork 5.3 ships with a hard-coded default API key (EONAPI_KEY in include/api_functions.php, API version 2.4.2) that is identical across all installations, so the flaw lives in the product's API authentication component. An unauthenticated remote attacker with network access can use that known key to calculate or guess the administrator access token, requiring no privileges, user interaction, or non-default configuration.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-23T07:09:37Z"},"cvss":{"score":9.8,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","provenance":"source","from":"NVD"},"epss":{"score":0.91874,"percentile":0.99817,"date":"2026-10-30","provenance":"source"},"kev":{"dateAdded":"2021-11-03","dueDate":"2022-05-03","ransomware":false,"requiredAction":"Apply updates per vendor instructions.","notes":"https://nvd.nist.gov/vuln/detail/CVE-2020-8657","provenance":"source"},"vulncheckKev":{"dateAdded":"2021-11-03","exploitedFirstSeen":"2021-11-03","ransomware":false,"evidence":[{"url":"https://www.cisa.gov/sites/default/files/feeds/known_exploited_vulnerabilities.json","date":"2021-11-03"},{"url":"https://app.crowdsec.net/cti/cve-explorer/CVE-2020-8657","date":"2025-10-16"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2026-09-21&host_type=src&vulnerability=cve-2020-8657","date":"2026-09-21"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2026-09-22&host_type=src&vulnerability=cve-2020-8657","date":"2026-09-22"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2026-09-23&host_type=src&vulnerability=cve-2020-8657","date":"2026-09-23"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2026-09-24&host_type=src&vulnerability=cve-2020-8657","date":"2026-09-24"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2026-09-25&host_type=src&vulnerability=cve-2020-8657","date":"2026-09-25"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2026-09-26&host_type=src&vulnerability=cve-2020-8657","date":"2026-09-26"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2026-09-27&host_type=src&vulnerability=cve-2020-8657","date":"2026-09-27"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2026-09-28&host_type=src&vulnerability=cve-2020-8657","date":"2026-09-28"}],"evidenceTotal":20,"provenance":"source"},"exploited":true,"otx":{"pulseCount":50,"pulses":[{"name":"Actively_Exploited_Kev | Oct 29, 2026","url":"https://otx.alienvault.com/pulse/6ae20c1db17e7057ae7d9ad1","created":"2026-10-28"},{"name":"Actively_Exploited_Kev | Oct 28, 2026","url":"https://otx.alienvault.com/pulse/6ae0ba7e0e2a97ff7b218819","created":"2026-10-27"},{"name":"Actively_Exploited_Kev | Oct 27, 2026","url":"https://otx.alienvault.com/pulse/6adf68b85c3e852f3c111d18","created":"2026-10-26"},{"name":"Actively_Exploited_Kev | Oct 24, 2026","url":"https://otx.alienvault.com/pulse/6adb740e397c3ad4799aa4cd","created":"2026-10-23"},{"name":"Actively_Exploited_Kev | Oct 23, 2026","url":"https://otx.alienvault.com/pulse/6ada236fcfba2dfa730ea482","created":"2026-10-22"},{"name":"Actively_Exploited_Kev | Oct 22, 2026","url":"https://otx.alienvault.com/pulse/6ad8d33a077cbb5cab524d80","created":"2026-10-21"},{"name":"Actively_Exploited_Kev | Oct 21, 2026","url":"https://otx.alienvault.com/pulse/6ad78130c4d1ac2be83a8b6d","created":"2026-10-20"},{"name":"Actively_Exploited_Kev | Oct 20, 2026","url":"https://otx.alienvault.com/pulse/6ad62f63c24a405a3423cc13","created":"2026-10-19"},{"name":"Actively_Exploited_Kev | Oct 19, 2026","url":"https://otx.alienvault.com/pulse/6ad4dda174e5797d0bd238b7","created":"2026-10-18"},{"name":"Actively_Exploited_Kev | Oct 18, 2026","url":"https://otx.alienvault.com/pulse/6ad38c22e1848f8189d1c121","created":"2026-10-17"}],"provenance":"machine"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"references":[{"url":"http://packetstormsecurity.com/files/156605/EyesOfNetwork-AutoDiscovery-Target-Command-Execution.html","tags":["Exploit","Third Party Advisory","VDB Entry"]},{"url":"https://github.com/EyesOfNetworkCommunity/eonapi/issues/17","tags":["Third Party Advisory"]},{"url":"http://packetstormsecurity.com/files/156605/EyesOfNetwork-AutoDiscovery-Target-Command-Execution.html","tags":["Exploit","Third Party Advisory","VDB Entry"]},{"url":"https://github.com/EyesOfNetworkCommunity/eonapi/issues/17","tags":["Third Party Advisory"]},{"url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2020-8657","tags":["US Government Resource"]}],"techniques":[{"id":"T1106","name":"Native API","tactics":["execution"],"provenance":"source","basis":"ctid-kev","bases":["ctid-kev"],"basisDetail":"CTID Mappings Explorer KEV 07/28/2025 (ATT&CK 16.1); capability: Hard-coded Credentials","mappingType":"exploitation_technique","evidence":[],"comment":"CVE-2020-8657 identifies a security issue in EyesOfNetwork 5.3 that exposes a vulnerability in the API key implementation.
