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-2023-34981 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 10.1.8; fixed in 10.1.9\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.8; fixed in 10.1.9\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M5; fixed in 11.0.0-M6\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M5; fixed in 11.0.0-M6\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.74; fixed in 9.0.75\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.74; fixed in 9.0.75\n- tomcat (Bitnami): affected from 8.5.88; fixed in 8.5.89, 9.0.75, 10.1.9\n- org.apache.tomcat:tomcat-coyote (Maven): affected from 8.5.88; fixed in 8.5.89\n- org.apache.tomcat:tomcat-coyote (Maven): affected from 8.5.88; fixed in 8.5.89\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-2023-34981/ (Markdown: https://insights.sbomify.com/CVE-2023-34981/index.md)","id":"CVE-2023-34981","markdown":"https://insights.sbomify.com/CVE-2023-34981/index.md","name":"CVE-2023-34981","record":{"aliases":["BIT-tomcat-2023-34981","DEBIAN-CVE-2023-34981","GHSA-mppv-79ch-vw6q","ROOT-APP-MAVEN-CVE-2023-34981"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"none","summary":"An Apache Tomcat regression causes AJP proxies to leak response headers from previous requests, exposing sensitive information to attackers.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"A regression in the fix for bug 66512 in Apache Tomcat 11.0.0-M5, 10.1.8, 9.0.74 and 8.5.88 meant that, if a response did not include any HTTP headers no AJP SEND_HEADERS messare woudl be sent for the response which in turn meant that at least one AJP proxy (mod_proxy_ajp) would use the response headers from the previous request leading to an information leak.","ecosystems":["Bitnami","Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Apache Tomcat: AJP response header mix-up","id":"CVE-2023-34981","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:tomcat","products":["apache:tomcat"],"type":"information_disclosure","year":"2023"},"n_packages":9,"n_references":2,"next":{"headline":"AVEVA Operations Control Logger External Control of File Name or Path","id":"CVE-2023-34982"},"packages":[{"ecosystem":"Bitnami","fixed":["8.5.89","9.0.75","10.1.9"],"introduced":["8.5.88","9.0.74","10.1.8"],"last_affected":[],"package":"tomcat","purl":"pkg:bitnami/tomcat","source":"BIT-tomcat-2023-34981"},{"ecosystem":"Maven","fixed":["10.1.9"],"introduced":["10.1.8"],"last_affected":[],"package":"org.apache.tomcat.embed:tomcat-embed-core","purl":null,"source":"GHSA-mppv-79ch-vw6q"},{"ecosystem":"Maven","fixed":["10.1.9"],"introduced":["10.1.8"],"last_affected":[],"package":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","source":"GHSA-mppv-79ch-vw6q"},{"ecosystem":"Maven","fixed":["11.0.0-M6"],"introduced":["11.0.0-M5"],"last_affected":[],"package":"org.apache.tomcat.embed:tomcat-embed-core","purl":null,"source":"GHSA-mppv-79ch-vw6q"},{"ecosystem":"Maven","fixed":["11.0.0-M6"],"introduced":["11.0.0-M5"],"last_affected":[],"package":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","source":"GHSA-mppv-79ch-vw6q"},{"ecosystem":"Maven","fixed":["9.0.75"],"introduced":["9.0.74"],"last_affected":[],"package":"org.apache.tomcat.embed:tomcat-embed-core","purl":null,"source":"GHSA-mppv-79ch-vw6q"},{"ecosystem":"Maven","fixed":["9.0.75"],"introduced":["9.0.74"],"last_affected":[],"package":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","source":"GHSA-mppv-79ch-vw6q"},{"ecosystem":"Maven","fixed":["8.5.89"],"introduced":["8.5.88"],"last_affected":[],"package":"org.apache.tomcat:tomcat-coyote","purl":null,"source":"GHSA-mppv-79ch-vw6q"},{"ecosystem":"Maven","fixed":["8.5.89"],"introduced":["8.5.88"],"last_affected":[],"package":"org.apache.tomcat:tomcat-coyote","purl":"pkg:maven/org.apache.tomcat/tomcat-coyote","source":"GHSA-mppv-79ch-vw6q"}],"prev":{"headline":"QTS, QuTS hero","id":"CVE-2023-34980"},"products":["Apache Tomcat"],"published":"2023-06-21","related":[{"cvss_score":10,"headline":"Apache Tomcat Path Equivalence","id":"CVE-2025-24813","kev_date_added":"2025-04-01","published":"2025-03-10"},{"cvss_score":9.8,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2016-8735","kev_date_added":"2023-05-12","published":"2017-04-06"},{"cvss_score":8.1,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2017-12617","kev_date_added":"2022-03-25","published":"2017-10-03"},{"cvss_score":8.1,"headline":"Apache Tomcat on Windows Remote Code Execution","id":"CVE-2017-12615","kev_date_added":"2022-03-25","published":"2017-09-19"},{"cvss_score":7.5,"headline":"Apache Tomcat Missing Encryption of Sensitive Data","id":"CVE-2026-34486","kev_date_added":"2026-08-04","published":"2026-04-09"},{"cvss_score":9.8,"headline":"Apache Tomcat: HTTP/2 no-authority bypass of strict SNI validation -
