This signature detects attempt to exploit a file overwrite vulnerability by passing specially crafted arguments into a method of PrecisionID Data Matrix Barcode ActiveX Control.
PrecisionID Data Matrix Barcode ActiveX Control is used to create barcode images.
The application is prone to multiple vulnerabilities that allow attackers to overwrite arbitrary local files. Specifically, the 'SaveBarCode()' and 'SaveEnhWMF()' methods of the vulnerable control will overwrite files in an insecure manner. The control is identified by CLSID:
Successful exploits will allow an attacker to corrupt and overwrite arbitrary files on the victim's computer in the context of an application using the ActiveX control (typically Internet Explorer).
