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-2020-18698 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- lin-cms (PyPI): affected all versions; no fix listed\n- lin-cms (PyPI): affected all versions; no fix listed\n- Lin-CMS (PyPI): affected all versions; no fix listed\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-2020-18698/ (Markdown: https://insights.sbomify.com/CVE-2020-18698/index.md)","id":"CVE-2020-18698","markdown":"https://insights.sbomify.com/CVE-2020-18698/index.md","name":"CVE-2020-18698","record":{"aliases":["GHSA-h6r2-pgvx-683c","PYSEC-2021-339"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Lin-CMS-Flask","requires_auth":"none","summary":"Remote attackers can perform unrestricted brute force login attempts on Lin-CMS-Flask, potentially leading to account takeover.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lin-cms-flask","vendor":"talelin"}],"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":"Improper Authentication in Lin-CMS-Flask v0.1.1 allows remote attackers to launch brute force login attempts without restriction via the 'login' function in the component 'app/api/cms/user.py'.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Lin-CMS-Flask vulnerable to Improper Authentication","id":"CVE-2020-18698","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":3,"n_references":2,"next":{"headline":"Lin-CMS-Flask Cross Site Scripting (XSS) vulnerability","id":"CVE-2020-18699"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":[],"last_affected":[],"package":"Lin-CMS","purl":null,"source":"GHSA-h6r2-pgvx-683c"},{"ecosystem":"PyPI","fixed":[],"introduced":[],"last_affected":[],"package":"lin-cms","purl":"pkg:pypi/lin-cms","source":"GHSA-h6r2-pgvx-683c"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":[],"package":"lin-cms","purl":"pkg:pypi/lin-cms","source":"PYSEC-2021-339"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-18694"},"products":["n/a"],"published":"2021-08-16","related":[{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-18701","kev_date_added":null,"published":"2021-08-16"},{"cvss_score":6.1,"headline":"Lin-CMS-Flask Cross Site Scripting (XSS) vulnerability","id":"CVE-2020-18699","kev_date_added":null,"published":"2021-08-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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 perform unrestricted brute force login attempts on Lin-CMS-Flask, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2020-18698/"}
