Vulnerability from pysec - Published: 2023-10-25 21:15 - Updated: 2023-11-02 16:33

Details

Twisted is an event-based framework for internet applications. Prior to version 23.10.0rc1, when sending multiple HTTP requests in one TCP packet, twisted.web will process the requests asynchronously without guaranteeing the response order. If one of the endpoints is controlled by an attacker, the attacker can delay the response on purpose to manipulate the response of the second request when a victim launched two requests using HTTP pipeline. Version 23.10.0rc1 contains a patch for this issue.

Severity

GHSA-XC8X-VP79-P3WM

Vulnerability from github – Published: 2023-10-25 21:15 – Updated: 2025-11-04 16:46

Summary

twisted.web has disordered HTTP pipeline response

Details

There's an example faulty program:

from twisted.internet import reactor, endpoints
from twisted.web import server
from twisted.web.proxy import ReverseProxyResource
from twisted.web.resource import Resource

class Second(Resource):
    isLeaf = True
    def render_GET(self, request):
        return b'SECOND\n'

class First(Resource):
    isLeaf = True
    def render_GET(self, request):
        def send_response():
            request.write(b'FIRST DELAYED\n')
            request.finish()
        reactor.callLater(0.5, send_response)
        return server.NOT_DONE_YET

root = Resource()

root.putChild(b'second', Second())
root.putChild(b'first', First())

endpoint = endpoints.TCP4ServerEndpoint(reactor, 8080)
endpoint.listen(server.Site(root))
reactor.run()

When two requests for /first and /second are sent in the same order, the second request will be responded to first.

echo -en "GET /first HTTP/1.1\r\nHost: a\r\n\r\nGET /second HTTP/1.1\r\nHost: a\r\n\r\n" | nc localhost 8080

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
