By crafting requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue is due to Gunicorn's handling of Transfer-Encoding headers, where it incorrectly processes requests with multiple, conflicting Transfer-Encoding headers, treating them as chunked regardless of the final encoding specified. This vulnerability allows for a range of attacks including cache poisoning, session manipulation, and data exposure."}],"affected":[{"vendor":"benoitc","product":"benoitc/gunicorn","versions":[{"version":"unspecified","status":"affected","versionType":"custom","lessThanOrEqual":"latest"}]}],"references":[{"url":"https://huntr.com/bounties/22158e34-cfd5-41ad-97e0-a780773d96c1"},{"url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00027.html"}],"metrics":[{"cvssV3_0":{"version":"3.0","attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","confidentialityImpact":"NONE","integrityImpact":"HIGH","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","baseScore":7.5,"baseSeverity":"HIGH"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-444 Inconsistent Interpretation of HTTP Requests","cweId":"CWE-444"}]}],"source":{"advisory":"22158e34-cfd5-41ad-97e0-a780773d96c1","discovery":"EXTERNAL"}},"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-1135","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2024-04-19T17:32:23.631972Z"}}}],"affected":[{"cpes":["cpe:2.3:a:benoitc:gunicorn:*:*:*:*:*:*:*:*"],"vendor":"benoitc","product":"gunicorn","versions":[{"status":"affected","version":"*"}],"defaultStatus":"unknown"}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-06-04T17:59:56.871Z"}},{"title":"CVE Program Container","references":[{"url":"https://huntr.com/bounties/22158e34-cfd5-41ad-97e0-a780773d96c1","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00027.html","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2024/12/msg00018.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-12-20T07:02:46.961Z"}}]},"dataVersion":"5.1"}
