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-2020-27218 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.eclipse.jetty:jetty-server (Maven): affected from 9.4.0; fixed in 9.4.35.v20201120\n- org.eclipse.jetty:jetty-server (Maven): affected from 9.4.0; fixed in 9.4.35.v20201120\n- kafka (Bitnami): affected from 2.7.0; fixed in 2.7.1\n- spark (Bitnami): affected from 2.4.8; fixed in 2.4.9, 3.0.4\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-2020-27218/ (Markdown: https://insights.sbomify.com/CVE-2020-27218/index.md)","id":"CVE-2020-27218","markdown":"https://insights.sbomify.com/CVE-2020-27218/index.md","name":"CVE-2020-27218","record":{"aliases":["BIT-kafka-2020-27218","BIT-spark-2020-27218","DEBIAN-CVE-2020-27218","GHSA-86wm-rrjm-8wh8","SUSE-SU-2020:3922-1","UBUNTU-CVE-2020-27218","openSUSE-SU-2021:0012-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Jetty web server","requires_auth":"none","summary":"Attackers can inject data into subsequent request bodies when GZIP inflation is enabled and requests are multiplexed, potentially corrupting application data.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"kafka","vendor":"apache"},{"product":"spark","vendor":"apache"},{"product":"debian_linux","vendor":"debian"},{"product":"jetty","vendor":"eclipse"},{"product":"oncommand_system_manager","vendor":"netapp"},{"product":"snap_creator_framework","vendor":"netapp"},{"product":"blockchain_platform","vendor":"oracle"},{"product":"communications_converged_application_server_-_service_controller","vendor":"oracle"},{"product":"communications_offline_mediation_controller","vendor":"oracle"},{"product":"communications_pricing_design_center","vendor":"oracle"},{"product":"communications_services_gatekeeper","vendor":"oracle"},{"product":"communications_session_route_manager","vendor":"oracle"},{"product":"flexcube_private_banking","vendor":"oracle"},{"product":"hyperion_infrastructure_technology","vendor":"oracle"},{"product":"rest_data_services","vendor":"oracle"},{"product":"retail_eftlink","vendor":"oracle"},{"product":"siebel_core_-_automation","vendor":"oracle"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-226","name":"Sensitive Information in Resource Not Removed Before Reuse"}],"description":"In Eclipse Jetty version 9.4.0.RC0 to 9.4.34.v20201102, 10.0.0.alpha0 to 10.0.0.beta2, and 11.0.0.alpha0 to 11.0.0.beta2, if GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single connection, and if an attacker can send a request with a body that is received entirely but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body.
