An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-6972 and fix it if it is affected.\n\nWhat it is: CVE-2020-6972 is a critical authentication bypass vulnerability in Honeywell Notifier Web Server (NWS) Version 3.50 and earlier, published on 24 Mar 2020. 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-2020-6972 in the wild and no public exploit code.\n\nAffected product: Honeywell Notifier Web Server (NWS) Version 3.50 and earlier. 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-2020-6972/ (Markdown: https://insights.sbomify.com/CVE-2020-6972/index.md)","id":"CVE-2020-6972","markdown":"https://insights.sbomify.com/CVE-2020-6972/index.md","name":"CVE-2020-6972","record":{"aliases":["GHSA-4pww-fgmg-2g7r"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Fire alarm web server","requires_auth":"none","summary":"Attackers can bypass authentication in Honeywell Notifier Web Server via capture-replay attacks, gaining unauthorized access to fire alarm systems.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"notifier_webserver","vendor":"honeywell"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"}],"description":"In Notifier Web Server (NWS) Version 3.50 and earlier, the Honeywell Fire Web Server’s authentication may be bypassed by a capture-replay attack from a web browser.","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 Notifier Web Server (NWS) Version 3.50 and earlier","id":"CVE-2020-6972","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in Digi International ConnectPort LTS 32 MEI","id":"CVE-2020-6973"},"packages":[],"prev":{"headline":"Privilege escalation in Emerson ValveLink","id":"CVE-2020-6971"},"products":["Notifier Web Server (NWS) Version 3.50 and earlier"],"published":"2020-03-24","related":[{"cvss_score":9.8,"headline":"Path traversal in Honeywell Notifier Web Server (NWS)","id":"CVE-2020-6974","kev_date_added":null,"published":"2020-04-07"}],"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":["Honeywell"]},"summary":"Attackers can bypass authentication in Honeywell Notifier Web Server via capture-replay attacks, gaining unauthorized access to fire alarm systems.","url":"https://insights.sbomify.com/CVE-2020-6972/"}
