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-2020-5401 in the wild and no public exploit code.\n\nAffected product: Cloud Foundry Routing. 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-2020-5401/ (Markdown: https://insights.sbomify.com/CVE-2020-5401/index.md)","id":"CVE-2020-5401","markdown":"https://insights.sbomify.com/CVE-2020-5401/index.md","name":"CVE-2020-5401","record":{"aliases":["GHSA-jgr4-5mrv-w8ph"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cloud Foundry GoRouter","requires_auth":"none","summary":"Malicious clients can poison the GoRouter cache by sending invalid headers, causing denial of service for legitimate users.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"pivotal","cpe":[{"product":"routing_release","vendor":"cloudfoundry"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.0"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"},{"id":"CWE-393","name":"Return of Wrong Status Code"}],"description":"Cloud Foundry Routing Release, versions prior to 0.197.0, contains GoRouter, which allows malicious clients to send invalid headers, causing caching layers to reject subsequent legitimate clients trying to access the app.","ecosystems":[],"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":"Cloud Foundry GoRouter is vulnerable to cache poisoning","id":"CVE-2020-5401","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"UAA fails to check the state parameter when authenticating with external IDPs","id":"CVE-2020-5402"},"packages":[],"prev":{"headline":"Cloud Controller logs environment variables from app manifests","id":"CVE-2020-5400"},"products":["Routing"],"published":"2020-02-27","related":[{"cvss_score":8.8,"headline":"Gorouter allows space developer to hijack route services hosted outside the platform","id":"CVE-2019-3789","kev_date_added":null,"published":"2019-04-24"}],"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":"2024-09-16","vendors":["Cloud Foundry"]},"summary":"Malicious clients can poison the GoRouter cache by sending invalid headers, causing denial of service for legitimate users.","url":"https://insights.sbomify.com/CVE-2020-5401/"}
