HTTP IDAutomation ActiveX File Overwrite

Severity: High

This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.


This signature detects attempts to exploit a file overwrite vulnerability in IDAutomation.

Additional Information

IDAutomation provides various ActiveX control barcode libraries that integrate with Microsoft Access, Excel, Infopath, Internet Explorer, Visual Basic, and C++.

IDAutomation Barcode ActiveX controls are prone to multiple vulnerabilities that allow attackers to overwrite arbitrary files.

These issues occur when 'SaveBarCode()' and 'SaveEnhWMF()' methods handle user-supplied data. The following ActiveX controls and related CLSIDs are affected:

IDAuto.BarCode.1(IDAutomationLinear6.dll) : 0C3874AA-AB39-4B5E-A768-45F3CE6C6819
IDAuto.Datamatrix.1(IDAutomationDMATRIX6.dll) : DB67DB99-616A-4CAB-A3A1-2EF644F254E7
IDAuto.PDF417.1(IDAutomationPDF417_6.dll) :E97EE6EB-7FBE-43B1-B6D8-C4D86C78C5A0
IDAuto.Aztec.1(IDAutomationAZTEC.dll) : EBA15B30-80B4-11DC-B31D-0050C2490048

An attacker can exploit these issues by enticing an unsuspecting victim to view a malicious HTML page.

Successfully exploiting these issues will allow the attacker to corrupt and overwrite arbitrary files on the victim's computer in the context of the vulnerable application using the ActiveX control (typically Internet Explorer).
