An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.
MEDIUM 6.6EPSS 1.15%
Does this matter?
Lower severity and a low EPSS score (1.15%). Track it; it rarely justifies an emergency change on its own.
Description
When processing project files, the application (Omron CX-Programmer v9.70 and prior and Common Components January 2019 and prior) fails to check if it is referencing freed memory. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.
