Vulnerability Description

Resource management errors vulnerability in a robot controller of MELFA FR Series(controller "CR800-*V*D" of RV-*FR***-D-* all versions, controller "CR800-*HD" of RH-*FRH***-D-* all versions, controller "CR800-*HRD" of RH-*FRHR***-D-* all versions, controller "CR800-*V*R with R16RTCPU" of RV-*FR***-R-* all versions, controller "CR800-*HR with R16RTCPU" of RH-*FRH***-R-* all versions, controller "CR800-*HRR with R16RTCPU" of RH-*FRHR***-R-* all versions, controller "CR800-*V*Q with Q172DSRCPU" of RV-*FR***-Q-* all versions, controller "CR800-*HQ with Q172DSRCPU" of RH-*FRH***-Q-* all versions, controller "CR800-*HRQ with Q172DSRCPU" of RH-*FRHR***-Q-* all versions) and a robot controller of MELFA CR Series(controller "CR800-CVD" of RV-8CRL-D-* all versions, controller "CR800-CHD" of RH-*CRH**-D-* all versions) as well as a cooperative robot ASSISTA(controller "CR800-05VD" of RV-5AS-D-* all versions) allows a remote unauthenticated attacker to cause a DoS of the execution of the robot program and the Ethernet communication by sending a large amount of packets in burst over a short period of time. As a result of DoS, an error may occur. A reset is required to recover it if the error occurs.
