HTTP/2: large amount of data request leads to denial of service - CVE-2019-9511ID: oval:org.secpod.oval:def:58202 | Date: (C)2019-10-10 (M)2024-04-17 |
Class: VULNERABILITY | Family: unix |
Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
