Detailsinfo

A vulnerability was found in ReactPHP HTTP up to 1.7.0 (JavaScript Library). It has been declared as problematic. This vulnerability affects some unknown functionality. The manipulation with an unknown input leads to a cookie validation vulnerability. The CWE definition for the vulnerability is CWE-565. The product relies on the existence or values of cookies when performing security-critical operations, but it does not properly ensure that the setting is valid for the associated user. As an impact it is known to affect integrity. CVE summarizes:

ReactPHP HTTP is a streaming HTTP client and server implementation for ReactPHP. In ReactPHP's HTTP server component versions starting with 0.7.0 and prior to 1.7.0, 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. This issue is fixed in ReactPHP HTTP version 1.7.0. As a workaround, Infrastructure or DevOps can place a reverse proxy in front of the ReactPHP HTTP server to filter out any unexpected `Cookie` request headers.
