Made by Mitsubishi Electric MELSEC iQ-R , Q and L Resource exhaustion vulnerability in the series

Trust: 0.8

sources: JVNDB: JVNDB-2020-009428

DESCRIPTION

Uncontrolled resource consumption vulnerability in Ethernet Port on MELSEC iQ-R, Q and L series CPU modules (R 00/01/02 CPU firmware versions '20' and earlier, R 04/08/16/32/120 (EN) CPU firmware versions '52' and earlier, R 08/16/32/120 SFCPU firmware versions '22' and earlier, R 08/16/32/120 PCPU all versions, R 08/16/32/120 PSFCPU all versions, R 16/32/64 MTCPU all versions, Q03 UDECPU, Q 04/06/10/13/20/26/50/100 UDEHCPU serial number '22081' and earlier , Q 03/04/06/13/26 UDVCPU serial number '22031' and earlier, Q 04/06/13/26 UDPVCPU serial number '22031' and earlier, Q 172/173 DCPU all versions, Q 172/173 DSCPU all versions, Q 170 MCPU all versions, Q 170 MSCPU all versions, L 02/06/26 CPU (-P) and L 26 CPU - (P) BT all versions) allows a remote unauthenticated attacker to stop the Ethernet communication functions of the products via a specially crafted packet, which may lead to a denial of service (DoS) condition . Provided by Mitsubishi Electric Corporation MELSEC iQ-R , Q and L Of the series CPU The unit has a resource exhaustion vulnerability. (CWE-400) exists. This vulnerability information is provided by the developer for the purpose of dissemination to product users. JPCERT/CC Report to JPCERT/CC Coordinated with the developer.When a packet crafted by a remote third party is received, Ethernet Communications disrupt service operations (DoS) may become a state. A reset is required for recovery
