Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-5416 in the wild and no public exploit code.\n\nAffected product: Cloud Foundry CF Deployment. 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-2020-5416/ (Markdown: https://insights.sbomify.com/CVE-2020-5416/index.md)","id":"CVE-2020-5416","markdown":"https://insights.sbomify.com/CVE-2020-5416/index.md","name":"CVE-2020-5416","record":{"aliases":[],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Cloud Foundry Routing","requires_auth":"low_privilege","summary":"Unauthenticated attackers can cause denial of service in Cloud Foundry deployments using NGINX reverse proxies by sending crafted HTTP requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"pivotal","cpe":[{"product":"cf-deployment","vendor":"cloudfoundry"},{"product":"routing-release","vendor":"cloudfoundry"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"Cloud Foundry Routing (Gorouter), versions prior to 0.204.0, when used in a deployment with NGINX reverse proxies in front of the Gorouters, is potentially vulnerable to denial-of-service attacks in which an unauthenticated malicious attacker can send specially-crafted HTTP requests that may cause the Gorouters to be dropped from the NGINX backend pool.","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":"CF clusters with NGINX in front of them may be vulnerable to DoS","id":"CVE-2020-5416","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cloud Controller may allow developers to claim sensitive routes","id":"CVE-2020-5417"},"packages":[],"prev":{"headline":"Concourse's GitLab auth allows impersonation","id":"CVE-2020-5415"},"products":["CF Deployment","Routing"],"published":"2020-08-21","related":[{"cvss_score":9.1,"headline":"Auth bypass in Cloud Foundry Diego and CF Deployment","id":"CVE-2022-31733","kev_date_added":null,"published":"2023-02-03"},{"cvss_score":8.8,"headline":"UAA fails to check the state parameter when authenticating with external IDPs","id":"CVE-2020-5402","kev_date_added":null,"published":"2020-02-27"},{"cvss_score":8.8,"headline":"UAA logs all query parameters with debug logging level","id":"CVE-2019-11293","kev_date_added":null,"published":"2019-12-06"},{"cvss_score":8.8,"headline":"Cloud Foundry UAA logs query parameters in tomcat access file","id":"CVE-2019-11290","kev_date_added":null,"published":"2019-11-25"},{"cvss_score":8.8,"headline":"Password leak in smbdriver logs","id":"CVE-2019-11283","kev_date_added":null,"published":"2019-10-23"},{"cvss_score":8.8,"headline":"Information disclosure in Garden-runC","id":"CVE-2018-1191","kev_date_added":null,"published":"2018-03-29"},{"cvss_score":8.7,"headline":"Java Projects using HTTP to fetch dependencies","id":"CVE-2019-3801","kev_date_added":null,"published":"2019-04-25"}],"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":"Unauthenticated attackers can cause denial of service in Cloud Foundry deployments using NGINX reverse proxies by sending crafted HTTP requests.","url":"https://insights.sbomify.com/CVE-2020-5416/"}
