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-2012-2374 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tornado (PyPI): affected all versions; fixed in 2.2.1\n- tornado (PyPI): affected all versions; fixed in 2.2.1\n- tornado (PyPI): affected all versions; fixed in 2.2.1\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-2012-2374/ (Markdown: https://insights.sbomify.com/CVE-2012-2374/index.md)","id":"CVE-2012-2374","markdown":"https://insights.sbomify.com/CVE-2012-2374/index.md","name":"CVE-2012-2374","record":{"aliases":["DEBIAN-CVE-2012-2374","GHSA-f7fv-v9rh-prvc","PYSEC-2012-5"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Python web framework","requires_auth":"none","summary":"Remote attackers can inject arbitrary HTTP headers and conduct response splitting attacks via crafted input in the Tornado web framework.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"tornado","vendor":"tornadoweb"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"CRLF injection vulnerability in the tornado.web.RequestHandler.set_header function in Tornado before 2.2.1 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via crafted input.","ecosystems":["PyPI"],"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":"Tornado CRLF injection vulnerability","id":"CVE-2012-2374","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"other","year":"2012"},"n_packages":3,"n_references":5,"next":{"headline":"Denial of service in n/a","id":"CVE-2012-2375"},"packages":[{"ecosystem":"PyPI","fixed":["2.2.1"],"introduced":["0"],"last_affected":[],"package":"tornado","purl":null,"source":"GHSA-f7fv-v9rh-prvc"},{"ecosystem":"PyPI","fixed":["2.2.1"],"introduced":["0"],"last_affected":[],"package":"tornado","purl":"pkg:pypi/tornado","source":"GHSA-f7fv-v9rh-prvc"},{"ecosystem":"PyPI","fixed":["2.2.1"],"introduced":["0"],"last_affected":[],"package":"tornado","purl":"pkg:pypi/tornado","source":"PYSEC-2012-5"}],"prev":{"headline":"Race condition in n/a","id":"CVE-2012-2373"},"products":["n/a"],"published":"2012-05-23","related":[{"cvss_score":8.7,"headline":"Tornado has a DoS due to too many multipart parts","id":"CVE-2026-31958","kev_date_added":null,"published":"2026-03-11"},{"cvss_score":7.5,"headline":"Tornado is Vulnerable to Quadratic DoS via Repeated Header Coalescing","id":"CVE-2025-67725","kev_date_added":null,"published":"2025-12-12"},{"cvss_score":7.5,"headline":"Tornado is Vulnerable to Quadratic DoS via Crafted Multipart Parameters","id":"CVE-2025-67726","kev_date_added":null,"published":"2025-12-12"},{"cvss_score":7.5,"headline":"Tornado has HTTP cookie parsing DoS vulnerability","id":"CVE-2024-52804","kev_date_added":null,"published":"2024-11-22"},{"cvss_score":7.2,"headline":"Tornado has incomplete validation of cookie attributes","id":"CVE-2026-35536","kev_date_added":null,"published":"2026-04-03"},{"cvss_score":6.5,"headline":"Tornado XSRF cookie allows side-channel attack against TLS (BREACH attack)","id":"CVE-2014-9720","kev_date_added":null,"published":"2020-01-24"},{"cvss_score":6.1,"headline":"Open redirect in Tornado","id":"CVE-2023-28370","kev_date_added":null,"published":"2023-05-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can inject arbitrary HTTP headers and conduct response splitting attacks via crafted input in the Tornado web framework.","url":"https://insights.sbomify.com/CVE-2012-2374/"}
