Risk evaluation
Multiple Murrelektronik network-enabled devices respond to SNMPv2c 'GETBULK' requests with disproportionately large response packets when the requesting party specifies a large max-repetitions value. This response amplification allows the affected devices to be misused as reflectors in distributed denial-of-service (DDoS) attacks against arbitrary third-party victims on the internet.
Mitigation summary
A firmware update that addresses the SNMP GETBULK response amplification behaviour is planned for release in early 2027 for the Murrelektronik MVK Pro and Impact67 Pro product lines. Until the fix becomes available, customers should apply the mitigations described above.
