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-2020-18701 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\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-2020-18701/ (Markdown: https://insights.sbomify.com/CVE-2020-18701/index.md)","id":"CVE-2020-18701","markdown":"https://insights.sbomify.com/CVE-2020-18701/index.md","name":"CVE-2020-18701","record":{"aliases":["GHSA-3m58-3m5q-53hq","PYSEC-2021-341"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Lin-CMS-Flask","requires_auth":"none","summary":"Attackers can replay authentication tokens after logout to gain unauthorized access and sensitive data in Lin-CMS-Flask.","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-863","name":"Incorrect Authorization"}],"description":"Incorrect Access Control in Lin-CMS-Flask v0.1.1 allows remote attackers to obtain sensitive information and/or gain privileges due to the application not invalidating a user's authentication token upon logout, which allows for replaying packets.","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":"Auth bypass in n/a","id":"CVE-2020-18701","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":1,"n_references":2,"next":{"headline":"Cross Site Scripting (XSS) in Quokka","id":"CVE-2020-18702"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":[],"package":"lin-cms","purl":"pkg:pypi/lin-cms","source":"PYSEC-2021-341"}],"prev":{"headline":"Lin-CMS-Flask Cross Site Scripting (XSS) vulnerability","id":"CVE-2020-18699"},"products":["n/a"],"published":"2021-08-16","related":[{"cvss_score":9.8,"headline":"Lin-CMS-Flask vulnerable to Improper Authentication","id":"CVE-2020-18698","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":"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":"Attackers can replay authentication tokens after logout to gain unauthorized access and sensitive data in Lin-CMS-Flask.","url":"https://insights.sbomify.com/CVE-2020-18701/"}
