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-2021-42850 in the wild and no public exploit code.\n\nAffected product: Lenovo Personal Cloud Storage A1. 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-2021-42850/ (Markdown: https://insights.sbomify.com/CVE-2021-42850/index.md)","id":"CVE-2021-42850","markdown":"https://insights.sbomify.com/CVE-2021-42850/index.md","name":"CVE-2021-42850","record":{"aliases":["GHSA-ch56-mgr4-g3m4"],"analysis":{"component_type":"iot_embedded","fix_type":"configuration_change","impacts":["account_takeover","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Personal Cloud Storage","requires_auth":"none","summary":"Attackers with local access can use weak default admin passwords to gain unauthorized access to Lenovo Personal Cloud Storage devices.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"a1_firmware","vendor":"lenovo"},{"product":"t1_firmware","vendor":"lenovo"},{"product":"t2_firmware","vendor":"lenovo"},{"product":"t2pro_firmware","vendor":"lenovo"},{"product":"x1_firmware","vendor":"lenovo"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"A weak default administrator password for the web interface and serial port was reported in some Lenovo Personal Cloud Storage devices that could allow unauthorized device access to an attacker with physical or local network access.","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 Personal Cloud Storage A1","id":"CVE-2021-42850","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":"Missing authorization in Personal Cloud Storage A1","id":"CVE-2021-42851"},"packages":[],"prev":{"headline":"Hardcoded credentials in Personal Cloud Storage A1","id":"CVE-2021-42849"},"products":["Personal Cloud Storage A1","Personal Cloud Storage T1","Personal Cloud Storage T2","Personal Cloud Storage T2Pro","Personal Cloud Storage X1"],"published":"2022-05-18","related":[{"cvss_score":8,"headline":"Command injection in Personal Cloud Storage A1","id":"CVE-2021-42852","kev_date_added":null,"published":"2022-05-18"},{"cvss_score":6.8,"headline":"Hardcoded credentials in Personal Cloud Storage A1","id":"CVE-2021-42849","kev_date_added":null,"published":"2022-05-18"},{"cvss_score":6.3,"headline":"Missing authorization in Personal Cloud Storage A1","id":"CVE-2021-42851","kev_date_added":null,"published":"2022-05-18"},{"cvss_score":4.3,"headline":"Information disclosure in Personal Cloud Storage A1","id":"CVE-2021-42848","kev_date_added":null,"published":"2022-05-18"}],"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":"2024-08-04","vendors":["Lenovo"]},"summary":"Attackers with local access can use weak default admin passwords to gain unauthorized access to Lenovo Personal Cloud Storage devices.","url":"https://insights.sbomify.com/CVE-2021-42850/"}
