Berlin-L21,Berlin-L21HN,Berlin-L22,Berlin-L22HN,Berlin-L23,Berlin-L24HN,FRD-L02,FRD-L04,FRD-L09,FRD-L14,FRD-L19,, published on 22 Nov 2017. 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-2017-2721 in the wild and no public exploit code.\n\nAffected product: Huawei Technologies Co., Ltd. Berlin-L21,Berlin-L21HN,Berlin-L22,Berlin-L22HN,Berlin-L23,Berlin-L24HN,FRD-L02,FRD-L04,FRD-L09,FRD-L14,FRD-L19,. 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-2017-2721/ (Markdown: https://insights.sbomify.com/CVE-2017-2721/index.md)","id":"CVE-2017-2721","markdown":"https://insights.sbomify.com/CVE-2017-2721/index.md","name":"CVE-2017-2721","record":{"aliases":["GHSA-26ch-2fxx-xjff"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["security_bypass","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Huawei smartphone","requires_auth":"none","summary":"Attackers can bypass Factory Reset Protection on Huawei smartphones via Swype Keyboard to update the Google account and gain unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"berlin-l21_firmware","vendor":"huawei"},{"product":"berlin-l21hn_firmware","vendor":"huawei"},{"product":"berlin-l22_firmware","vendor":"huawei"},{"product":"berlin-l22hn_firmware","vendor":"huawei"},{"product":"berlin-l23_firmware","vendor":"huawei"},{"product":"berlin-l24hn_firmware","vendor":"huawei"},{"product":"frd-l02_firmware","vendor":"huawei"},{"product":"frd-l04_firmware","vendor":"huawei"},{"product":"frd-l09_firmware","vendor":"huawei"},{"product":"frd-l14_firmware","vendor":"huawei"},{"product":"frd-l19_firmware","vendor":"huawei"}],"cvss":{"score":4.6,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Some Huawei smart phones with software Berlin-L21C10B130,Berlin-L21C185B133,Berlin-L21HNC10B131,Berlin-L21HNC185B140,Berlin-L21HNC432B151,Berlin-L22C636B160,Berlin-L22HNC636B130,Berlin-L22HNC675B150CUSTC675D001,Berlin-L23C605B131,Berlin-L24HNC567B110,FRD-L02C432B120,FRD-L02C635B130,FRD-L02C675B170CUSTC675D001,FRD-L04C567B162,FRD-L04C605B131,FRD-L09C10B130,FRD-L09C185B130,FRD-L09C432B131,FRD-L09C636B130,FRD-L14C567B162,FRD-L19C10B130,FRD-L19C432B131,FRD-L19C636B130 have a factory Reset Protection (FRP) bypass security vulnerability.
