Vulnerability from github – Published: 2024-12-12 19:22 – Updated: 2024-12-12 22:31

Summary

http4k has a potential XXE (XML External Entity Injection) vulnerability

Details

Summary

Short summary of the problem. Make the impact and severity as clear as possible. For example: An unsafe deserialization vulnerability allows any unauthenticated user to execute arbitrary code on the server.

There is a potential XXE(XML External Entity Injection) vulnerability when http4k handling malicious XML contents within requests, which might allow attackers to read local sensitive information on server, trigger Server-side Request Forgery and even execute code under some circumstances.

Details

Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer. https://github.com/http4k/http4k/blob/25696dff2d90206cc1da42f42a1a8dbcdbcdf18c/core/format/xml/src/main/kotlin/org/http4k/format/Xml.kt#L42-L46 XML contents is parsed with DocumentBuilder without security settings on or external entity enabled

PoC

Complete instructions, including specific configuration details, to reproduce the vulnerability.

Example Vulnerable server code:

import org.http4k.core.*
import org.http4k.format.Xml.xml
import org.http4k.server.Netty
import org.http4k.server.asServer
import org.w3c.dom.Document

fun main() {

    val xmlLens = Body.xml().toLens()

    // Create an HTTP handler
    val app: HttpHandler = { request ->
        try {
            // Parse the incoming XML payload to a Document object
            val xmlDocument: Document = xmlLens(request)

            // Extract root element name or other details from the XML
            val rootElementName = xmlDocument.documentElement.nodeName

            // Create a response XML based on the extracted information
            val responseXml = """
                <response>
                    <message>Root element is: $rootElementName</message>
                </response>
            """.trimIndent()

            // Respond with XML
            Response(Status.OK).body(responseXml).header("Content-Type", "application/xml")
        } catch (e: Exception) {
            // Handle invalid XML or other errors
            Response(Status.BAD_REQUEST).body("Invalid XML: ${e.message}")
        }
    }

    // Start the server
    val server = app.asServer(Netty(9000)).start()
