17167

--
Summary:
This event is generated when an attempt is made to exploit a known vulnerability in an ActiveX control.

--
Impact:
A successful attack can cause a buffer overflow and the subsequent execution of arbitrary code with system level privileges on a vulnerable host.

--
Detailed Information:
A vulnerability exists in the way that Internet Explorer handles ActiveX controls that may present an attacker with the opportunity to run code of their choosing on a host.

In particular, this event is generated when a call to the siebel option pack ie activex control is made. This may indicate an attempt to exploit known vulnerabilities in that ActiveX control which may lead to a system compromise.

The Oracle Siebel Option Pack for IE ActiveX control does not properly initialize memory that is used by the NewBusObj method, which allows remote attackers to execute arbitrary code via a crafted HTML document.

NOTE: For this detection to work comprehensively, the flow depth setting in the HTTP Inspect preprocessor must be set to 0
