Summary

Improper Validation of Array Index in Packetbeat Leading to Denial of Service

Details

Improper Validation of Array Index (CWE-129) in the PostgreSQL protocol parser in Packetbeat can lead Denial of Service via Input Data Manipulation (CAPEC-153). An attacker can send a specially crafted packet causing a Go runtime panic that terminates the Packetbeat process. This vulnerability requires the pgsql protocol to be explicitly enabled and configured to monitor traffic on the targeted port.
