VULNERABILITY DETAILS


This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mitsubishi Electric E-Designer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within processing of a driver configuration file when initializing the BEMatsushita component. When parsing the property TCP_IP_Address, the process fails to properly validate the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code in the context of the Administrator.

VENDOR RESPONSE Mitsubishi Electric has issued an update to correct this vulnerability. More details can be found at:
