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-2020-21237 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-2020-21237/ (Markdown: https://insights.sbomify.com/CVE-2020-21237/index.md)","id":"CVE-2020-21237","markdown":"https://insights.sbomify.com/CVE-2020-21237/index.md","name":"CVE-2020-21237","record":{"aliases":["GHSA-qmgf-hqxv-72p7"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"LJCMS","requires_auth":"none","summary":"Attackers can hijack user accounts in LJCMS via brute force attacks on the login box due to insufficient authentication controls.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ljcms","vendor":"8cms"}],"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":"An issue in the user login box of LJCMS v1.11 allows attackers to hijack user accounts via brute force attacks.","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-2020-21237","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in n/a","id":"CVE-2020-21238"},"packages":[],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-21236"},"products":["n/a"],"published":"2021-12-27","related":[{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2020-20735","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2020-20979","kev_date_added":null,"published":"2021-08-12"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2020-20583","kev_date_added":null,"published":"2021-07-08"}],"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 hijack user accounts in LJCMS via brute force attacks on the login box due to insufficient authentication controls.","url":"https://insights.sbomify.com/CVE-2020-21237/"}
