Elastic Beats packetbeat 8.0.x < 8.19.24 / 9.0.x < 9.4.9 / 9.5.x < 9.5.6 DoS (ESA-2026-208)

medium Nessus Plugin ID 377041

Synopsis

Elastic Beats packetbeat installed on the remote Windows host is affected by a denial of service vulnerability.

Description

The version of Elastic Beats packetbeat installed on the remote host is 8.0.x prior to 8.19.24, 9.0.x prior to 9.4.9, or 9.5.x prior to 9.5.6. It is, therefore, affected by a denial of service vulnerability.

- NULL Pointer Dereference (CWE-476) in the AMQP protocol parser in Packetbeat can lead to a denial of service via specially crafted network traffic. An unauthenticated attacker who can send traffic on a network segment that Packetbeat monitors for AMQP can cause a Go runtime panic that terminates the Packetbeat process. A single crafted packet is sufficient. No AMQP authentication is necessary. While Packetbeat is not running, it does not collect network telemetry. Packetbeat is affected when the AMQP protocol is enabled, which is the default configuration.
(CVE-2026-115297)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Elastic Beats packetbeat version 8.19.24, 9.4.9, 9.5.6 or later.
