Specially crafted requests containing special whitespace characters in the Transfer-Encoding header would get parsed by Waitress as being a chunked request, but a front-end server would use the Content-Length instead as the Transfer-Encoding header is considered invalid due to containing invalid characters. If a front-end server does HTTP pipelining to a backend Waitress server this could lead to HTTP request splitting which may lead to potential cache poisoning or unexpected information disclosure.

When request lookahead is disabled (default) we won\u0027t read any more requests, and when the first request fails due to a parsing error, we simply close the connection. However when request lookahead is enabled, it is possible to process and receive the first request, start sending the error message back to the client while we read the next request and queue it. This will allow the secondary request to be serviced by the worker thread while the connection should be closed. Waitress 3.0.1 fixes the race condition. As a workaround, disable channel_request_lookahead, this is set to 0 by default disabling this feature." } ], "metrics": [ { "cvssV3_1": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 9.1, "baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N", "version": "3.1" } } ], "problemTypes": [ { "descriptions": [ { "cweId": "CWE-367", "description": "CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition", "lang": "en", "type": "CWE" } ] }, { "descriptions": [ { "cweId": "CWE-444", "description": "CWE-444: Inconsistent Interpretation of HTTP Requests (\u0027HTTP Request/Response Smuggling\u0027)", "lang": "en", "type": "CWE" } ] } ], "providerMetadata": { "dateUpdated": "2024-10-29T14:32:25.164Z", "orgId": "a0819718-46f1-4df5-94e2-005712e83aaa", "shortName": "GitHub_M" }, "references": [ { "name": "https://github.com/Pylons/waitress/security/advisories/GHSA-9298-4cf8-g4wj", "tags": [ "x_refsource_CONFIRM" ], "url": "https://github.com/Pylons/waitress/security/advisories/GHSA-9298-4cf8-g4wj" }, { "name": "https://github.com/Pylons/waitress/commit/e4359018537af376cf24bd13616d861e2fb76f65", "tags": [ "x_refsource_MISC" ], "url": "https://github.com/Pylons/waitress/commit/e4359018537af376cf24bd13616d861e2fb76f65" } ], "source": { "advisory": "GHSA-9298-4cf8-g4wj", "discovery": "UNKNOWN" }, "title": "Waitress has request processing race condition in HTTP pipelining with invalid first request" } }, "cveMetadata": { "assignerOrgId": "a0819718-46f1-4df5-94e2-005712e83aaa", "assignerShortName": "GitHub_M", "cveId": "CVE-2024-49768", "datePublished": "2024-10-29T14:32:25.164Z", "dateReserved": "2024-10-18T13:43:23.457Z", "dateUpdated": "2024-10-29T14:56:02.111Z", "state": "PUBLISHED" }, "dataType": "CVE_RECORD", "dataVersion": "5.1" }
