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.
AnalysisAI
Packetbeat's MongoDB protocol parser fails to properly validate array indices, enabling attackers to trigger buffer overflows via malformed network packets sent to monitored interfaces. Organizations running Packetbeat with MongoDB protocol parsing enabled could experience denial of service conditions when processing specially crafted traffic. No patch is currently available for this vulnerability.
