HTTP: OMRON CX-One CX-Programmer Program Use After Free

This signature detects attempts to exploit a known vulnerability against OMRON CX-One CX-Programmer module. The vulnerability is due to input validation error when processing Program parameter of the CX-Programmer project files. A remote attacker could exploit this vulnerability by enticing a target user into opening a maliciously crafted project file. Successful exploitation could result in arbitrary code execution in the context of the target user.

Extended 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.
