An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-40422 exists.\n\nAffected product: Swift Sensors Gateway. 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-2021-40422/ (Markdown: https://insights.sbomify.com/CVE-2021-40422/index.md)","id":"CVE-2021-40422","markdown":"https://insights.sbomify.com/CVE-2021-40422/index.md","name":"CVE-2021-40422","record":{"aliases":["GHSA-qrg2-vh9f-gq55"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Swift Sensors Gateway","requires_auth":"none","summary":"An attacker can bypass authentication via crafted network requests to achieve remote code execution on Swift Sensors Gateways.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"sg3-1010_firmware","vendor":"swiftsensors"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"},{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"An authentication bypass vulnerability exists in the device password generation functionality of Swift Sensors Gateway SG3-1010.
