Summary
HTTP/2 DoS Attacks: Ping, Reset, and Settings Floods
Details
Impact
Twisted web servers that utilize the optional HTTP/2 support suffer from the following flow-control related vulnerabilities:
Ping flood: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-9512 Reset flood: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-9514 Settings flood: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-9515
A Twisted web server supports HTTP/2 requests if you've installed the http2 optional dependency set.
Workarounds
There are no workarounds.

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.
