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-2020-12702 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-2020-12702/ (Markdown: https://insights.sbomify.com/CVE-2020-12702/index.md)","id":"CVE-2020-12702","markdown":"https://insights.sbomify.com/CVE-2020-12702/index.md","name":"CVE-2020-12702","record":{"aliases":["GHSA-4hq8-rhcf-fxwv"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"eWeLink mobile app","requires_auth":"none","summary":"Weak encryption in eWeLink app pairing allows nearby attackers to eavesdrop on Wi-Fi credentials and sensitive data.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ewelink","vendor":"coolkit"}],"cvss":{"score":4.6,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"Weak encryption in the Quick Pairing mode in the eWeLink mobile application (Android application V4.9.2 and earlier, iOS application V4.9.1 and earlier) allows physically proximate attackers to eavesdrop on Wi-Fi credentials and other sensitive information by monitoring the Wi-Fi spectrum during the pairing process.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2020-01-11","github_poc":2,"max_poc_stars":5,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-01-11T13:15:53Z","kind":"github_poc","ref":"https://github.com/salgio/ESPTouchCatcher","stars":5,"title":"eWeLinkESPT is a tool that automatically decodes and decrypts the WiFi network credentials transmitted to a supported ESP-based IoT device by the eWeLink mobile application.
