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-2021-35327 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-2021-35327/ (Markdown: https://insights.sbomify.com/CVE-2021-35327/index.md)","id":"CVE-2021-35327","markdown":"https://insights.sbomify.com/CVE-2021-35327/index.md","name":"CVE-2021-35327","record":{"aliases":["GHSA-w5cw-c968-jv2x"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TOTOLINK router","requires_auth":"none","summary":"Attackers can enable Telnet and log in with default credentials via a crafted POST request, gaining unauthorized access to the router.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"a720r_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-862","name":"Missing Authorization"}],"description":"A vulnerability in TOTOLINK A720R A720R_Firmware v4.1.5cu.470_B20200911 allows attackers to start the Telnet service, then login with the default credentials via a crafted POST request.","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":"Missing authorization in n/a","id":"CVE-2021-35327","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in n/a","id":"CVE-2021-35331"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-35326"},"products":["n/a"],"published":"2021-08-05","related":[{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2023-23064","kev_date_added":null,"published":"2023-02-17"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2021-45740","kev_date_added":null,"published":"2022-02-04"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-45742","kev_date_added":null,"published":"2022-02-04"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2021-35324","kev_date_added":null,"published":"2021-08-05"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-27708","kev_date_added":null,"published":"2021-04-14"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-27710","kev_date_added":null,"published":"2021-04-14"}],"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":"Attackers can enable Telnet and log in with default credentials via a crafted POST request, gaining unauthorized access to the router.","url":"https://insights.sbomify.com/CVE-2021-35327/"}
