F5 Networks BIG-IP : HTTP/2 Reset Flood vulnerability (K01988340)

high Nessus Plugin ID 129308

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. (CVE-2019-9514)

Impact

The BIG-IP system may exhaust available resources and fail over to another system in the device group.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K01988340.
