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-2021-34267 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-34267/ (Markdown: https://insights.sbomify.com/CVE-2021-34267/index.md)","id":"CVE-2021-34267","markdown":"https://insights.sbomify.com/CVE-2021-34267/index.md","name":"CVE-2021-34267","record":{"aliases":["GHSA-9pmv-cwwx-vvjr"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"STM32 USB middleware","requires_auth":"none","summary":"A flaw in the USB mass storage interface initialization allows attackers to cause a denial of service via malicious endpoint communication.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"stm32cube_middleware","vendor":"st"}],"cvss":{"score":4.6,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"An in the USBH_MSC_InterfaceInit() function of STMicroelectronics STM32Cube Middleware v1.8.0 and below causes a denial of service (DOS) when the system tries to communicate with the connected endpoint.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Denial of service in n/a","id":"CVE-2021-34267","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-34268"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-34262"},"products":["n/a"],"published":"2021-07-22","related":[{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2021-34259","kev_date_added":null,"published":"2021-07-22"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2021-34260","kev_date_added":null,"published":"2021-07-22"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2021-34262","kev_date_added":null,"published":"2021-07-22"},{"cvss_score":4.6,"headline":"Denial of service in n/a","id":"CVE-2021-34261","kev_date_added":null,"published":"2021-07-22"},{"cvss_score":4.6,"headline":"Denial of service in n/a","id":"CVE-2021-34268","kev_date_added":null,"published":"2021-07-22"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A flaw in the USB mass storage interface initialization allows attackers to cause a denial of service via malicious endpoint communication.","url":"https://insights.sbomify.com/CVE-2021-34267/"}
