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-2023-40167 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.eclipse.jetty:jetty-http (Maven): affected from 10.0.0; fixed in 10.0.16\n- org.eclipse.jetty:jetty-http (Maven): affected from 10.0.0; fixed in 10.0.16\n- org.eclipse.jetty:jetty-http (Maven): affected from 11.0.0; fixed in 11.0.16\n- org.eclipse.jetty:jetty-http (Maven): affected from 11.0.0; fixed in 11.0.16\n- org.eclipse.jetty:jetty-http (Maven): affected from 12.0.0; fixed in 12.0.1\n- org.eclipse.jetty:jetty-http (Maven): affected from 12.0.0; fixed in 12.0.1\n- org.eclipse.jetty:jetty-http (Maven): affected from 9.0.0; fixed in 9.4.52\n- org.eclipse.jetty:jetty-http (Maven): affected from 9.0.0; fixed in 9.4.52\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-2023-40167/ (Markdown: https://insights.sbomify.com/CVE-2023-40167/index.md)","id":"CVE-2023-40167","markdown":"https://insights.sbomify.com/CVE-2023-40167/index.md","name":"CVE-2023-40167","record":{"aliases":["CLEANSTART-2025-JQ80087","CLEANSTART-2026-AW54675","CLEANSTART-2026-ID49738","DEBIAN-CVE-2023-40167","ECHO-996c-7d65-3491","GHSA-hmr7-m48g-48f6","MINI-26cw-mrv8-76xm","MINI-7xw9-968j-4566","MINI-rjxh-58fh-p47p","UBUNTU-CVE-2023-40167"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web server","requires_auth":"none","summary":"Jetty improperly accepts plus-prefixed Content-Length headers, potentially enabling request smuggling in specific proxy configurations.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"jetty","vendor":"eclipse"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-130","name":"Improper Handling of Length Parameter Inconsistency"}],"description":"Jetty is a Java based web server and servlet engine. Prior to versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1, Jetty accepts the `+` character proceeding the content-length value in a HTTP/1 header field.  This is more permissive than allowed by the RFC and other servers routinely reject such requests with 400 responses.  There is no known exploit scenario, but it is conceivable that request smuggling could result if jetty is used in combination with a server that does not close the connection after sending such a 400 response. Versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1 contain a patch for this issue.
