It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-12586 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2019-12586/ (Markdown: https://insights.sbomify.com/CVE-2019-12586/index.md)","id":"CVE-2019-12586","markdown":"https://insights.sbomify.com/CVE-2019-12586/index.md","name":"CVE-2019-12586","record":{"aliases":["GHSA-jj4g-g9rr-33cr"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ESP-IDF SDK","requires_auth":"none","summary":"Attackers in radio range can crash Espressif ESP-IDF and ESP8266 devices by sending crafted EAP Success messages before method completion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"arduino-esp32","vendor":"espressif"},{"product":"esp-idf","vendor":"espressif"},{"product":"esp8266_nonos_sdk","vendor":"espressif"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[],"description":"The EAP peer implementation in Espressif ESP-IDF 2.0.0 through 4.0.0 and ESP8266_NONOS_SDK 2.2.0 through 3.1.0 processes EAP Success messages before any EAP method completion or failure, which allows attackers in radio range to cause a denial of service (crash) via a crafted message.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2019-09-03","github_poc":1,"max_poc_stars":823,"metasploit":0,"nuclei":0,"refs":[{"date":"2019-09-03T15:08:49Z","kind":"github_poc","ref":"https://github.com/Matheus-Garbelini/esp32_esp8266_attacks","stars":823,"title":"Proof of Concept of ESP32/8266 Wi-Fi vulnerabilties (CVE-2019-12586, CVE-2019-12587, CVE-2019-12588)"}],"tier":"poc_unverified"},"has_fix":false,"headline":"Denial of service in n/a","id":"CVE-2019-12586","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":3,"next":{"headline":"Weak cryptography in n/a","id":"CVE-2019-12587"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2019-12585"},"products":["n/a"],"published":"2019-09-04","related":[{"cvss_score":9.8,"headline":"arduino-esp32: Stack buffer overflow in WebServer multipart boundary parsing leads to remote crash potential RCE","id":"CVE-2026-42854","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":8.8,"headline":"Improper validation of NBNS name_len in arduino-esp32 NetBIOS leads to memory corruption","id":"CVE-2026-41429","kev_date_added":null,"published":"2026-04-24"},{"cvss_score":7.5,"headline":"arduino-esp32: Digest authentication URI mismatch bypass in WebServer allows cross-resource replay attack","id":"CVE-2026-42855","kev_date_added":null,"published":"2026-05-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers in radio range can crash Espressif ESP-IDF and ESP8266 devices by sending crafted EAP Success messages before method completion.","url":"https://insights.sbomify.com/CVE-2019-12586/"}
