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-2021-27451 in the wild and no public exploit code.\n\nAffected product: Mesa Labs AmegaView. 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-2021-27451/ (Markdown: https://insights.sbomify.com/CVE-2021-27451/index.md)","id":"CVE-2021-27451","markdown":"https://insights.sbomify.com/CVE-2021-27451/index.md","name":"CVE-2021-27451","record":{"aliases":["GHSA-8gx6-q6q9-c678"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"AmegaView device","requires_auth":"none","summary":"An attacker can bypass authentication on Mesa Labs AmegaView devices by reversing the passcode generation algorithm to gain unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"amegaview","vendor":"mesalabs"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Mesa Labs AmegaView Versions 3.0 and prior’s passcode is generated by an easily reversible algorithm, which may allow an attacker to gain access 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":"Mesa Labs AmegaView improper authentication","id":"CVE-2021-27451","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded credentials in MU320E","id":"CVE-2021-27452"},"packages":[],"prev":{"headline":"Weak cryptography in MU320E","id":"CVE-2021-27450"},"products":["AmegaView"],"published":"2021-12-21","related":[{"cvss_score":10,"headline":"Mesa Labs AmegaView command injection","id":"CVE-2021-27447","kev_date_added":null,"published":"2021-12-21"},{"cvss_score":9.9,"headline":"Mesa Labs AmegaView Command Injection","id":"CVE-2021-27449","kev_date_added":null,"published":"2021-12-21"},{"cvss_score":7.8,"headline":"Mesa Labs AmegaView Improper Privilege Management","id":"CVE-2021-27445","kev_date_added":null,"published":"2021-12-21"},{"cvss_score":7.3,"headline":"Mesa Labs AmegaView authentication bypass","id":"CVE-2021-27453","kev_date_added":null,"published":"2021-12-21"}],"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":"2024-09-16","vendors":["Mesa Labs"]},"summary":"An attacker can bypass authentication on Mesa Labs AmegaView devices by reversing the passcode generation algorithm to gain unauthorized access.","url":"https://insights.sbomify.com/CVE-2021-27451/"}
