An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3681 in the wild and no public exploit code.\n\nAffected product: Qualcomm, Inc. 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-2020-3681/ (Markdown: https://insights.sbomify.com/CVE-2020-3681/index.md)","id":"CVE-2020-3681","markdown":"https://insights.sbomify.com/CVE-2020-3681/index.md","name":"CVE-2020-3681","record":{"aliases":["GHSA-xr9p-wqhw-3w78"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Qualcomm HPAV2 firmware","requires_auth":"none","summary":"Attackers can forge authenticated HomePlug AV2 messages using a hardcoded key, enabling remote code execution on affected devices.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qualcomm","cpe":[{"product":"-","vendor":"qualcomm"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"Authenticated and encrypted payload MMEs can be forged and remotely sent to any HPAV2 system using a jailbreak key recoverable from code.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Weak cryptography in n/a","id":"CVE-2020-3681","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-3682"},"packages":[],"prev":{"headline":"Race condition in Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Wearables","id":"CVE-2020-3680"},"products":["n/a"],"published":"2020-07-31","related":[],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Qualcomm, Inc."]},"summary":"Attackers can forge authenticated HomePlug AV2 messages using a hardcoded key, enabling remote code execution on affected devices.","url":"https://insights.sbomify.com/CVE-2020-3681/"}
