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-2023-46589 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.0-M1; fixed in 10.1.16\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.0-M1; fixed in 10.1.16\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.0-M11\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.0-M11\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.5.0; fixed in 8.5.96\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.5.0; fixed in 8.5.96\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0-M1; fixed in 9.0.83\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0-M1; fixed in 9.0.83\n- tomcat (Bitnami): affected from 8.5.0; fixed in 8.5.96, 9.0.83, 10.1.16\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 10.1.0-M1; fixed in 10.1.16\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 10.1.0-M1; fixed in 10.1.16\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 11.0.0-M1; fixed in 11.0.0-M11\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-2023-46589/ (Markdown: https://insights.sbomify.com/CVE-2023-46589/index.md)","id":"CVE-2023-46589","markdown":"https://insights.sbomify.com/CVE-2023-46589/index.md","name":"CVE-2023-46589","record":{"aliases":["ALSA-2024:0539","ALSA-2024:1134","BIT-tomcat-2023-46589","CLSA-2024-1705081413","CLSA-2024-1707420277","CLSA-2025-1742924802","CLSA-2026-1775608274","CLSA-2026-1784164036","DEBIAN-CVE-2023-46589","DLA-3707-1","GHSA-fccv-jmmp-qg76","RHSA-2024:0532","RHSA-2024:0539","RHSA-2024:1092","RHSA-2024:1134","RLSA-2024:0539","ROOT-APP-MAVEN-CVE-2023-46589","SUSE-SU-2024:0206-1","SUSE-SU-2024:0208-1","SUSE-SU-2024:0209-1","UBUNTU-CVE-2023-46589","USN-7032-1","openSUSE-SU-2024:13590-1","openSUSE-SU-2024:13596-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Attackers can smuggle HTTP requests via malformed trailer headers in Apache Tomcat, potentially bypassing security controls or accessing unauthorized data.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through 10.1.15, from 9.0.0-M1 through 9.0.82 and from 8.5.0 through 8.5.95 did not correctly parse HTTP trailer headers.
