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-2020-16839 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-2020-16839/ (Markdown: https://insights.sbomify.com/CVE-2020-16839/index.md)","id":"CVE-2020-16839","markdown":"https://insights.sbomify.com/CVE-2020-16839/index.md","name":"CVE-2020-16839","record":{"aliases":["GHSA-899f-m5f4-9vc7"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Crestron DM-NVX devices","requires_auth":"none","summary":"An unauthenticated attacker can change the device password via a WebSocket request, leading to full account takeover on Crestron DM-NVX devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dm-nvx-dir-160_firmware","vendor":"crestron"},{"product":"dm-nvx-dir-80_firmware","vendor":"crestron"},{"product":"dm-nvx-dir-ent_firmware","vendor":"crestron"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"On Crestron DM-NVX-DIR, DM-NVX-DIR80, and DM-NVX-ENT devices before the DM-XIO/1-0-3-802 patch, the password can be changed by sending an unauthenticated WebSocket request.","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":"Auth bypass in n/a","id":"CVE-2020-16839","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-16843"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-16836"},"products":["n/a"],"published":"2021-07-27","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":["n/a"]},"summary":"An unauthenticated attacker can change the device password via a WebSocket request, leading to full account takeover on Crestron DM-NVX devices.","url":"https://insights.sbomify.com/CVE-2020-16839/"}
