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-2021-47706 in the wild and no public exploit code.\n\nAffected product: COMMAX Biometric Access Control System. 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-2021-47706/ (Markdown: https://insights.sbomify.com/CVE-2021-47706/index.md)","id":"CVE-2021-47706","markdown":"https://insights.sbomify.com/CVE-2021-47706/index.md","name":"CVE-2021-47706","record":{"aliases":["GHSA-wqx6-ghvg-724j"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Biometric Access Control System","requires_auth":"none","summary":"Unauthenticated attackers can forge cookies to bypass authentication, accessing sensitive information and circumventing physical security controls in smart buildings.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-565","name":"Reliance on Cookies without Validation and Integrity Checking"}],"description":"COMMAX Biometric Access Control System 1.0.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to access sensitive information and circumvent physical controls in smart homes and buildings by exploiting cookie poisoning.
