[GSS](7.1.z) UNDERTOW-1185 - Undertow does not allow UTF-8 characters in URLs

XMLWordPrintable

    • EAP 7.1.1

      We receive a 400 response code if using UTF-8 characters for a request, due to this check:

      https://github.com/undertow-io/undertow/blob/master/core/src/main/java/io/undertow/server/protocol/http/HttpRequestParser.java#L375

      This was introduced in UNDERTOW-1101. We want to understand why it is necessary for the CVE/CWE regarding request smuggling, but this ticket is to at least make this check optional as it goes against the URL_ENCODING UndertowOption when set to UTF-8 (default).
