Details

ReactPHP's HTTP server parses encoded cookie names so malicious `__Host-` and `__Secure-` cookies can be sent ### Impact In 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. ### Patches * https://github.com/reactphp/http/commit/663c9a3b77b71463fa7fcb76a6676ffd16979dd6 - Fixed in [reactphp/http `v1.7.0`](https://github.com/reactphp/http/releases/tag/v1.7.0) ### Workarounds Infrastructure or DevOps can place a reverse proxy in front of the ReactPHP HTTP server to filter out any unexpected `Cookie` request headers. ### References * CVE-2020-7070, https://bugs.php.net/bug.php?id=79699 and https://github.com/php/php-src/commit/6559fe912661ca5ce5f0eeeb591d928451428ed0 * CVE-2020-8184, https://hackerone.com/reports/895727 and https://github.com/rack/rack/commit/1f5763de6a9fe515ff84992b343d63c88104654c * Originally introduced via https://github.com/reactphp/http/pull/175 ### Credits * Thanks to Marco Squarcina (TU Wien) for reporting this and working with us to coordinate this security advisory ### For more information If you have any questions or comments about this advisory: * [Join the discussion](https://github.com/orgs/reactphp/discussions/465) * Email us at support@reactphp.org
