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-2020-14993 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-2020-14993/ (Markdown: https://insights.sbomify.com/CVE-2020-14993/index.md)","id":"CVE-2020-14993","markdown":"https://insights.sbomify.com/CVE-2020-14993/index.md","name":"CVE-2020-14993","record":{"aliases":["GHSA-56hp-cj87-42wh"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"DrayTek router","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on DrayTek routers via a stack-based buffer overflow in the SMS authentication handler.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"vigor2960_firmware","vendor":"draytek"},{"product":"vigor300b_firmware","vendor":"draytek"},{"product":"vigor3900_firmware","vendor":"draytek"}],"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-787","name":"Out-of-bounds Write"}],"description":"A stack-based buffer overflow on DrayTek Vigor2960, Vigor3900, and Vigor300B devices before 1.5.1.1 allows remote attackers to execute arbitrary code via the formuserphonenumber parameter in an authusersms action to mainfunction.cgi.","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-2020-14993","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2020-14999"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2020-14990"},"products":["n/a"],"published":"2020-06-23","related":[{"cvss_score":9.8,"headline":"DrayTek Multiple Vigor Routers OS Command Injection","id":"CVE-2020-15415","kev_date_added":"2024-09-30","published":"2020-06-30"},{"cvss_score":9.8,"headline":"Multiple DrayTek Vigor Routers Web Management Page","id":"CVE-2020-8515","kev_date_added":"2021-11-03","published":"2020-02-01"},{"cvss_score":6.9,"headline":"DrayTek Vigor Routers OS Command Injection","id":"CVE-2024-12987","kev_date_added":"2025-05-15","published":"2024-12-27"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-42911","kev_date_added":null,"published":"2022-03-29"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-43118","kev_date_added":null,"published":"2022-03-29"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2020-14472","kev_date_added":null,"published":"2020-06-24"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14473","kev_date_added":null,"published":"2020-06-24"}],"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":"Remote attackers can execute arbitrary code on DrayTek routers via a stack-based buffer overflow in the SMS authentication handler.","url":"https://insights.sbomify.com/CVE-2020-14993/"}
