VAR-202107-0288
Vulnerability from variot - Updated: 2023-12-18 11:30NULL Pointer Dereference in MELSEC-F Series FX3U-ENET firmware version 1.14 and prior, FX3U-ENET-L firmware version 1.14 and prior and FX3U-ENET-P502 firmware version 1.14 and prior allows a remote unauthenticated attacker to cause a DoS condition in communication by sending specially crafted packets. Control by MELSEC-F series PLC is not affected and system reset is required for recovery. Made by Mitsubishi Electric MELSEC F series Ethernet Interface blocks NULL Pointer reference (CWE-476 , CVE-2021-20596) A vulnerability exists. This vulnerability information is provided by the developer for the purpose of making it known to product users. JPCERT/CC Report to JPCERT/CC Coordinated with the developers.If the product receives a malicious packet crafted by a remote third party, an error will occur and communication will interfere with service operation. (DoS) It may be in a state. In addition, by resetting the system, service operation is interrupted. (DoS) Recovery from the state is possible. According to the developer MELSEC F It has no effect on the control of the basic units of the series. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Misubishi Electric Mitsubishi Electric MELSEC-F Series is a basic micro PLC with scalability of analog and communication functions for industrial control equipment of Mitsubishi Electric Corporation. Mitsubishi Electric MELSEC-F Series contains a code issue vulnerability that could cause a denial of service condition for communication with the product
