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-2021-34262 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-2021-34262/ (Markdown: https://insights.sbomify.com/CVE-2021-34262/index.md)","id":"CVE-2021-34262","markdown":"https://insights.sbomify.com/CVE-2021-34262/index.md","name":"CVE-2021-34262","record":{"aliases":["GHSA-w3h6-g4rf-x858"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"STM32 USB middleware","requires_auth":"none","summary":"A buffer overflow in STM32Cube Middleware allows attackers to execute arbitrary code via crafted USB descriptors.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"stm32cube_middleware","vendor":"st"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow vulnerability in the USBH_ParseEPDesc() function of STMicroelectronics STM32Cube Middleware v1.8.0 and below allows attackers to execute arbitrary code.","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":"Memory corruption in n/a","id":"CVE-2021-34262","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-34267"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-34261"},"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":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-2021-34267","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":"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":["n/a"]},"summary":"A buffer overflow in STM32Cube Middleware allows attackers to execute arbitrary code via crafted USB descriptors.","url":"https://insights.sbomify.com/CVE-2021-34262/"}
