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-2020-24987 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-2020-24987/ (Markdown: https://insights.sbomify.com/CVE-2020-24987/index.md)","id":"CVE-2020-24987","markdown":"https://insights.sbomify.com/CVE-2020-24987/index.md","name":"CVE-2020-24987","record":{"aliases":["GHSA-q9jc-x24x-r9x9"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Tenda AC18 Router","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Tenda AC18 routers by bypassing authentication in the logincheck function when the admin UI is configured to use RADIUS.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac18_firmware","vendor":"tendacn"}],"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-287","name":"Improper Authentication"}],"description":"Tenda AC18 Router through V15.03.05.05_EN and through V15.03.05.19(6318) CN devices could cause a remote code execution due to incorrect authentication handling of vulnerable logincheck() function in /usr/lib/lua/ngx_authserver/ngx_wdas.lua file if the administrator UI Interface is set to \"radius\".","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":"Auth bypass in n/a","id":"CVE-2020-24987","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Path traversal in n/a","id":"CVE-2020-24990"},"packages":[],"prev":{"headline":"File upload in n/a","id":"CVE-2020-24986"},"products":["n/a"],"published":"2020-09-04","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-33180","kev_date_added":null,"published":"2024-07-16"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-31446","kev_date_added":null,"published":"2022-06-14"},{"cvss_score":8.3,"headline":"Memory corruption in n/a","id":"CVE-2024-33182","kev_date_added":null,"published":"2024-07-16"}],"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 Tenda AC18 routers by bypassing authentication in the logincheck function when the admin UI is configured to use RADIUS.","url":"https://insights.sbomify.com/CVE-2020-24987/"}
