{"id":"GHSA-w3w9-vrf5-8mx8","summary":"ReactPHP's HTTP server parses encoded cookie names so malicious `__Host-` and `__Secure-` cookies can be sent","details":"### Impact\n\nIn ReactPHP's HTTP server component versions below v1.7.0, when ReactPHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like `__Host-` and `__Secure-` confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. See also CVE-2020-7070 and CVE-2020-8184 for more information. \n\n### Patches\n\n* https://github.com/reactphp/http/commit/663c9a3b77b71463fa7fcb76a6676ffd16979dd6 - Fixed in [reactphp/http `v1.7.0`](https://github.com/reactphp/http/releases/tag/v1.7.0)\n\n### Workarounds\n\nInfrastructure or DevOps can place a reverse proxy in front of the ReactPHP HTTP server to filter out any unexpected `Cookie` request headers.\n\n### References\n\n* CVE-2020-7070, https://bugs.php.net/bug.php?id=79699 and https://github.com/php/php-src/commit/6559fe912661ca5ce5f0eeeb591d928451428ed0\n* CVE-2020-8184, https://hackerone.com/reports/895727 and https://github.com/rack/rack/commit/1f5763de6a9fe515ff84992b343d63c88104654c\n* Originally introduced via https://github.com/reactphp/http/pull/175\n\n### Credits\n\n* Thanks to Marco Squarcina (TU Wien) for reporting this and working with us to coordinate this security advisory\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* [Join the discussion](https://github.com/orgs/reactphp/discussions/465)\n* Email us at support@reactphp.org\n","aliases":["CVE-2022-36032"],"modified":"2023-11-08T04:09:58.360057Z","published":"2022-09-16T18:48:53Z","database_specific":{"nvd_published_at":"2022-09-06T19:15:00Z","cwe_ids":["CWE-20","CWE-565"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2022-09-16T18:48:53Z"},"references":[{"type":"WEB","url":"https://github.com/reactphp/http/security/advisories/GHSA-w3w9-vrf5-8mx8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36032"},{"type":"WEB","url":"https://github.com/reactphp/http/pull/175"},{"type":"WEB","url":"https://github.com/reactphp/http/commit/663c9a3b77b71463fa7fcb76a6676ffd16979dd6"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/react/http/CVE-2022-36032.yaml"},{"type":"PACKAGE","url":"https://github.com/reactphp/http"},{"type":"WEB","url":"https://github.com/reactphp/http/releases/tag/v1.7.0"}],"affected":[{"package":{"name":"react/http","ecosystem":"Packagist","purl":"pkg:composer/react/http"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.7.0"},{"fixed":"1.7.0"}]}],"versions":["v0.7.0","v0.7.1","v0.7.2","v0.7.3","v0.7.4","v0.8.0","v0.8.1","v0.8.2","v0.8.3","v0.8.4","v0.8.5","v0.8.6","v0.8.7","v1.0.0","v1.1.0","v1.2.0","v1.3.0","v1.4.0","v1.5.0","v1.6.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-w3w9-vrf5-8mx8/GHSA-w3w9-vrf5-8mx8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
