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-2021-34577 in the wild and no public exploit code.\n\nAffected product: Kaden PICOFLUX AiR. 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-2021-34577/ (Markdown: https://insights.sbomify.com/CVE-2021-34577/index.md)","id":"CVE-2021-34577","markdown":"https://insights.sbomify.com/CVE-2021-34577/index.md","name":"CVE-2021-34577","record":{"aliases":["GHSA-q3wx-xp39-27ph"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"water meter","requires_auth":"none","summary":"An attacker with physical proximity can read water meter data using a hardcoded key in wireless M-Bus mode.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"picoflux_air_firmware","vendor":"kadenvodomery"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"In the Kaden PICOFLUX AiR water meter an adversary can read the values through wireless M-Bus mode 5 with a hardcoded shared key while being adjacent to the device.","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":"Hardcoded credentials in Kaden PICOFLUX AiR","id":"CVE-2021-34577","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"WAGO: Authentication Vulnerability in Web-Based Management","id":"CVE-2021-34578"},"packages":[],"prev":{"headline":"Observable discrepancy in Kaden PICOFLUX AiR leaks water consumption","id":"CVE-2021-34576"},"products":["PICOFLUX AiR"],"published":"2022-11-09","related":[{"cvss_score":4.3,"headline":"Observable discrepancy in Kaden PICOFLUX AiR leaks water consumption","id":"CVE-2021-34576","kev_date_added":null,"published":"2021-09-16"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-01","vendors":["Kaden"]},"summary":"An attacker with physical proximity can read water meter data using a hardcoded key in wireless M-Bus mode.","url":"https://insights.sbomify.com/CVE-2021-34577/"}
