An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-41834 in the wild and no public exploit code.\n\nAffected product: Apache Flink Stateful Functions. 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-2023-41834/ (Markdown: https://insights.sbomify.com/CVE-2023-41834/index.md)","id":"CVE-2023-41834","markdown":"https://insights.sbomify.com/CVE-2023-41834/index.md","name":"CVE-2023-41834","record":{"aliases":["GHSA-v965-25gx-6h45"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Flink Stateful Functions","requires_auth":"none","summary":"Remote attackers can inject arbitrary HTTP headers and conduct response splitting attacks via crafted requests in Apache Flink Stateful Functions.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"flink_stateful_functions","vendor":"apache"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-113","name":"Improper Neutralization of CRLF Sequences in HTTP Headers"}],"description":"Improper Neutralization of CRLF Sequences in HTTP Headers in Apache Flink Stateful Functions 3.1.0, 3.1.1 and 3.2.0 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via crafted HTTP requests. Attackers could potentially inject malicious content into the HTTP response that is sent to the user's browser. \n\nUsers should upgrade to Apache Flink Stateful Functions version 3.3.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache Flink Stateful Functions allowed HTTP header injection due to Improper Neutralization of CRLF Sequences","id":"CVE-2023-41834","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Apache Struts: excessive disk usage","id":"CVE-2023-41835"},"packages":[],"prev":{"headline":"Race condition in UEFI firmware for some Intel(R) processors","id":"CVE-2023-41833"},"products":["Apache Flink Stateful Functions"],"published":"2023-09-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["Apache Software Foundation"]},"summary":"Remote attackers can inject arbitrary HTTP headers and conduct response splitting attacks via crafted requests in Apache Flink Stateful Functions.","url":"https://insights.sbomify.com/CVE-2023-41834/"}
