CWE-129

Description

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.

Affected configurations

• elasticsearch packetbeat (>= 8.0.0 < 8.19.11) • elasticsearch packetbeat (>= 9.0.0 < 9.2.5)
