CVE-2017-20211Network attack vector

Remote code execution via unchecked pointer dereference

Published Nov 12, 2025 · Updated Nov 12, 2025

Untrusted pointer dereference in UCanCode E-XD++ Visualization Enterprise Suite allows remote attackers to execute code through ActiveX. The TKDRAWCAD.TKDrawCADCtrl.1 control exposes RotateShape, which dereferences a user-supplied value as a pointer without validation. Exploitation requires the target to visit a malicious page or open a malicious file, and successful code execution inherits the hosting process context.
