VAR-202006-1953

Vulnerability from variot - Updated: 2022-05-04 09:21

GX Work2 is a PLC programming software developed by Mitsubishi Electric Automation Co., Ltd. It is a programming tool dedicated to PLC design, debugging, and maintenance. Compared with the traditional GX Developer software, it has improved functions and operating performance and has become easier to use.

GX Works2 has a denial of service vulnerability. When an attacker clicks on the PLC online read function, the malformed data sent by the PLC to GX Work2 through a private protocol causes a heap overflow vulnerability, which leads to a denial of service and may cause remote code execution.
