CVE-2023-44487

HIGH KEV LAB

HTTP/2 - Denial of Service via Rapid Stream Reset

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2023-44487 is actively exploited and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, added October 10, 2023. EIP tracks 30 public exploits from researchers including Madhusudhan Rajappa, bcdannyboy, secengjeff.

AI-analyzed exploit summary This Python script exploits CVE-2023-44487 (HTTP/2 Rapid Reset vulnerability) by rapidly creating and resetting HTTP/2 streams to trigger a denial-of-service condition. It uses the h2 library to establish an HTTP/2 connection and measures the server's response to the attack.

Description

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
