4Description
Improper Validation of Array Index (CWE-129) in multiple protocol parser components in Packetbeat can lead Denial of Service via Input Data Manipulation (CAPEC-153). An attacker with the ability to send specially crafted, malformed network packets to a monitored network interface can trigger out-of-bounds read operations, resulting in application crashes or resource exhaustion. This requires the attacker to be positioned on the same network segment as the Packetbeat deployment or to control traffic routed to monitored interfaces.
Analysis
Packetbeat contains an improper array index validation vulnerability (CWE-129) in its protocol parser components that allows attackers to trigger out-of-bounds read operations through specially crafted network packets. Affected versions include Packetbeat 8.0.0 through 8.19.10 and 9.0.0 through 9.2.4, with the vulnerability requiring network-level access or traffic control to the monitored interface. …
