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-2022-24801 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- twisted (PyPI): affected all versions; fixed in 22.4.0\n- twisted (PyPI): affected all versions; fixed in 22.4.0\n- Twisted (PyPI): affected all versions; fixed in 22.4.0\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-2022-24801/ (Markdown: https://insights.sbomify.com/CVE-2022-24801/index.md)","id":"CVE-2022-24801","markdown":"https://insights.sbomify.com/CVE-2022-24801/index.md","name":"CVE-2022-24801","record":{"aliases":["DEBIAN-CVE-2022-24801","DLA-2991-1","GHSA-c2jg-hw38-jrqq","PYSEC-2022-195","RHSA-2022:1645","RHSA-2022:1646","RHSA-2022:4930","SUSE-SU-2022:1477-1","SUSE-SU-2022:1546-1","UBUNTU-CVE-2022-24801","USN-5576-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Python web framework","requires_auth":"none","summary":"Lenient HTTP parsing in Twisted Web server allows request smuggling when proxied, enabling cache poisoning or access control bypass.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"zfs_storage_appliance_kit","vendor":"oracle"},{"product":"twisted","vendor":"twisted"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the `twisted.web.http` module, parsed several HTTP request constructs more leniently than permitted by RFC 7230. This non-conformant parsing can lead to desync if requests pass through multiple HTTP parsers, potentially resulting in HTTP request smuggling. Users who may be affected use Twisted Web's HTTP 1.1 server and/or proxy and also pass requests through a different HTTP server and/or proxy. The Twisted Web client is not affected. The HTTP 2.0 server uses a different parser, so it is not affected. The issue has been addressed in Twisted 22.4.0rc1. Two workarounds are available: Ensure any vulnerabilities in upstream proxies have been addressed, such as by upgrading them; or filter malformed requests by other means, such as configuration of an upstream proxy.","ecosystems":["PyPI","Red Hat:enterprise_linux:7::client","Red Hat:enterprise_linux:7::computenode","Red Hat:enterprise_linux:7::server","Red Hat:enterprise_linux:7::workstation","Red
