    "title": "NetX Duo Web HTTP server interprets request body content as HTTP header fields",
    "summary": "The Web add-on's HTTP server searches the entire request packet for header fields instead of stopping at the end of the header section. A header field name placed in the request body is therefore reported to the server as though it were a header, which lets a client control request framing decisions it should not be able to reach.",
