It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-30355 in the wild and no public exploit code.\n\nAffected product: Amazon Kindle e-reader. 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-2021-30355/ (Markdown: https://insights.sbomify.com/CVE-2021-30355/index.md)","id":"CVE-2021-30355","markdown":"https://insights.sbomify.com/CVE-2021-30355/index.md","name":"CVE-2021-30355","record":{"aliases":["GHSA-c9v4-rxrm-vmc5"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Amazon Kindle e-reader","requires_auth":"none","summary":"An attacker with framework user access can elevate privileges to root on Amazon Kindle e-readers, compromising device security.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"checkpoint","cpe":[{"product":"kindle_firmware","vendor":"amazon"}],"cvss":{"score":8.6,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Amazon Kindle e-reader prior to and including version 5.13.4 improperly manages privileges, allowing the framework user to elevate privileges to root.","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":"Privilege escalation in Amazon Kindle e-reader","id":"CVE-2021-30355","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Check Point Identity Agent","id":"CVE-2021-30356"},"packages":[],"prev":{"headline":"Integer overflow in Amazon Kindle e-reader","id":"CVE-2021-30354"},"products":["Amazon Kindle e-reader"],"published":"2021-09-01","related":[{"cvss_score":8.6,"headline":"Integer overflow in Amazon Kindle e-reader","id":"CVE-2021-30354","kev_date_added":null,"published":"2021-09-01"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"An attacker with framework user access can elevate privileges to root on Amazon Kindle e-readers, compromising device security.","url":"https://insights.sbomify.com/CVE-2021-30355/"}
