An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-43636 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-2021-43636/ (Markdown: https://insights.sbomify.com/CVE-2021-43636/index.md)","id":"CVE-2021-43636","markdown":"https://insights.sbomify.com/CVE-2021-43636/index.md","name":"CVE-2021-43636","record":{"aliases":["GHSA-3c89-xf6c-m942"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"T10 Firmware","requires_auth":"none","summary":"Buffer overflow in T10 firmware HTTP parser allows attackers to execute arbitrary code or cause denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"t10_v2_firmware","vendor":"totolink"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/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":"Two Buffer Overflow vulnerabilities exists in T10 V2_Firmware V4.1.8cu.5207_B20210320 in the http_request_parse function when processing host data in the HTTP request process.","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":"Memory corruption in n/a","id":"CVE-2021-43636","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":"Memory corruption in n/a","id":"CVE-2021-43637"},"packages":[],"prev":{"headline":"A Cross Site Scripting (XSS) vulnerability exists in Codex before 1.4.0 via Notebook/Page name field, which allows malicious users to execut","id":"CVE-2021-43635"},"products":["n/a"],"published":"2022-03-25","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-40041","kev_date_added":null,"published":"2023-08-08"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-40042","kev_date_added":null,"published":"2023-08-08"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-25081","kev_date_added":null,"published":"2022-02-22"}],"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":"Buffer overflow in T10 firmware HTTP parser allows attackers to execute arbitrary code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2021-43636/"}
