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-2023-20882 in the wild and no public exploit code.\n\nAffected product: Cloud Foundry Routing release. 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-2023-20882/ (Markdown: https://insights.sbomify.com/CVE-2023-20882/index.md)","id":"CVE-2023-20882","markdown":"https://insights.sbomify.com/CVE-2023-20882/index.md","name":"CVE-2023-20882","record":{"aliases":["GHSA-f2f8-4q6m-2pw8"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cloud Foundry Routing","requires_auth":"none","summary":"Attackers can cause denial of service for Cloud Foundry applications by prematurely closing client connections, triggering backend removal from the routing pool.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"cf-deployment","vendor":"cloudfoundry"},{"product":"routing_release","vendor":"cloudfoundry"}],"cvss":{"score":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"In Cloud foundry routing release versions from 0.262.0 and prior to 0.266.0,a bug in the gorouter process can lead to a denial of service of applications hosted on Cloud Foundry.
