Signature Detail

HTTP: Microsoft SQL Server DMO Exploit

This signature detects attempts to exploit a known vulnerability in Microsoft SQL Server Distributed Management Objects. An attacker can create malicious Web pages containing dangerous ActiveX calls, which if accessed by a victim, allows the attacker to gain control of the victim's client browse

Extended Description

Microsoft SQL Server 'sqldmo.dll' ActiveX Control is prone to a buffer-overflow vulnerability because it fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer. Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Failed exploit attempts likely result in denial-of-service conditions.
