CVE-2020-11080 (GCVE-0-2020-11080)

Vulnerability from cvelistv5 – Published: 2020-06-03 00:00 – Updated: 2025-06-09 15:45

Title

Denial of service in nghttp2

Summary

In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection.

Severity ?

3.7 (Low)
