The original report notes that some versions of Apache Traffic Server and HAProxy have been vulnerable in the past. HTTP request smuggling may be a serious concern if you use a proxy to perform request validation or access control.\n\nThe Twisted Web client is not affected. The HTTP 2.0 server uses a different parser, so it is not affected.\n\n### Patches\n\nThe issue has been addressed in Twisted 22.4.0rc1 and later.\n\n### Workarounds\n\nOther than upgrading Twisted, you could:\n\n* Ensure any vulnerabilities in upstream proxies have been addressed, such as by upgrading them\n* Filter malformed requests by other means, such as configuration of an upstream proxy\n\n### Credits\n\nThis issue was initially reported by [Zhang Zeyu](https://github.com/zeyu2001).", "cvss3": {"exploitabilityScore": 2.2, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "HIGH", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 8.1, "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-04-04T21:29:41", "type": "github", "title": "Inconsistent Interpretation of HTTP Requests in twisted.web", "bulletinFamily": "software", "cvss2": {"severity": "MEDIUM", "exploitabilityScore": 8.6, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "MEDIUM", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 6.8, "vectorString": "AV:N/AC:M/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 6.4, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-24801"], "modified": "2022-07-27T04:29:47", "id": "GHSA-C2JG-HW38-JRQQ", "href": "https://github.com/advisories/GHSA-c2jg-hw38-jrqq", "cvss": {"score": 6.8, "vector": "AV:N/AC:M/Au:N/C:P/I:P/A:P"}}], "ubuntu": [{"lastseen": "2022-11-03T18:34:21", "description": "It was discovered that Twisted incorrectly parsed some types of HTTP requests \nin its web server implementation.
