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-2021-41435 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-2021-41435/ (Markdown: https://insights.sbomify.com/CVE-2021-41435/index.md)","id":"CVE-2021-41435","markdown":"https://insights.sbomify.com/CVE-2021-41435/index.md","name":"CVE-2021-41435","record":{"aliases":["GHSA-hjq5-v65p-2p24"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"ASUS router firmware","requires_auth":"none","summary":"Remote attackers can bypass CAPTCHA protection to perform unlimited login attempts on vulnerable ASUS routers.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gt-ax11000_firmware","vendor":"asus"},{"product":"rt-ax3000_firmware","vendor":"asus"},{"product":"rt-ax55_firmware","vendor":"asus"},{"product":"rt-ax56u_firmware","vendor":"asus"},{"product":"rt-ax56u_v2_firmware","vendor":"asus"},{"product":"rt-ax58u_firmware","vendor":"asus"},{"product":"rt-ax68u_firmware","vendor":"asus"},{"product":"rt-ax82u_firmware","vendor":"asus"},{"product":"rt-ax82u_gundam_edition_firmware","vendor":"asus"},{"product":"rt-ax86s_firmware","vendor":"asus"},{"product":"rt-ax86u_firmware","vendor":"asus"},{"product":"rt-ax86u_zaku_ii_edition_firmware","vendor":"asus"},{"product":"rt-ax88u_firmware","vendor":"asus"},{"product":"rt-ax92u_firmware","vendor":"asus"},{"product":"tuf-ax5400_firmware","vendor":"asus"},{"product":"tuf_gaming_ax3000_firmware","vendor":"asus"},{"product":"zenwifi_ax_\\(xt8\\)_firmware","vendor":"asus"},{"product":"zenwifi_xd6_firmware","vendor":"asus"}],"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-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"A brute-force protection bypass in CAPTCHA protection in ASUS ROG Rapture GT-AX11000, RT-AX3000, RT-AX55, RT-AX56U, RT-AX56U_V2, RT-AX58U, RT-AX82U, RT-AX82U GUNDAM EDITION, RT-AX86 Series(RT-AX86U/RT-AX86S), RT-AX86U ZAKU II EDITION, RT-AX88U, RT-AX92U, TUF Gaming AX3000, TUF Gaming AX5400 (TUF-AX5400), ASUS ZenWiFi XD6, ASUS ZenWiFi AX (XT8) before 3.0.0.4.386.45898, and RT-AX68U before 3.0.0.4.386.45911, allows a remote attacker to attempt any number of login attempts via sending a specific HTTP 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":"Security feature bypass in n/a","id":"CVE-2021-41435","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":7,"next":{"headline":"Other in n/a","id":"CVE-2021-41436"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-41434"},"products":["n/a"],"published":"2021-11-19","related":[{"cvss_score":7.5,"headline":"Other in n/a","id":"CVE-2021-41436","kev_date_added":null,"published":"2021-11-19"}],"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":"2026-07-09","vendors":["n/a"]},"summary":"Remote attackers can bypass CAPTCHA protection to perform unlimited login attempts on vulnerable ASUS routers.","url":"https://insights.sbomify.com/CVE-2021-41435/"}
