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-2021-38384 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- serverless-offline (npm): affected all versions up to 8.0.0; no fix listed\n- serverless-offline (npm): affected all versions up to 8.0.0; 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-2021-38384/ (Markdown: https://insights.sbomify.com/CVE-2021-38384/index.md)","id":"CVE-2021-38384","markdown":"https://insights.sbomify.com/CVE-2021-38384/index.md","name":"CVE-2021-38384","record":{"aliases":["GHSA-h97f-5258-5593"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Serverless Offline tool","requires_auth":"none","summary":"Serverless Offline returns 403 for trailing slashes unlike AWS, potentially leading developers to implement incorrect access controls and bypass security.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"serverless_offline","vendor":"serverless_offline_project"}],"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-755","name":"Improper Handling of Exceptional Conditions"}],"description":"Serverless Offline 8.0.0 returns a 403 HTTP status code for a route that has a trailing / character, which might cause a developer to implement incorrect access control, because the actual behavior within the Amazon AWS environment is a 200 HTTP status code (i.e., possibly greater than expected permissions).","ecosystems":["npm"],"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":"Incorrect Authorization in serverless-offline","id":"CVE-2021-38384","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-38385"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["8.0.0"],"package":"serverless-offline","purl":null,"source":"GHSA-h97f-5258-5593"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["8.0.0"],"package":"serverless-offline","purl":"pkg:npm/serverless-offline","source":"GHSA-h97f-5258-5593"}],"prev":{"headline":"Use after free in n/a","id":"CVE-2021-38383"},"products":["n/a"],"published":"2021-08-10","related":[],"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":"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":"Serverless Offline returns 403 for trailing slashes unlike AWS, potentially leading developers to implement incorrect access controls and bypass security.","url":"https://insights.sbomify.com/CVE-2021-38384/"}
