Summary
Improper Validation of Array Index (CWE-129) in Packetbeat’s MongoDB protocol parser can allow an attacker to cause Overflow Buffers (CAPEC-100) through specially crafted network traffic. This requires an attacker to send a malformed payload to a monitored network interface where MongoDB protocol parsing is enabled.
