HTTP: Dangerous Visual Basic Unsafe ActiveX Control Access

This signature detects attempts to exploit a known vulnerability against Visual Basic ActiveX controls. An attacker can create a malicious Web site containing dangerous ActiveX elements, which if accessed by a victim, allows the attacker to take control of the victim's client browser and execute arbitrary code.

Extended Description

Microsoft Hierarchical FlexGrid ActiveX control is prone to a remote memory-corruption vulnerability. Remote attackers can exploit this issue to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Successful exploits will compromise the application and possibly the underlying computer. Failed attacks will cause denial-of-service conditions. Microsoft Hierarchical FlexGrid Control 6.0.88.4 is vulnerable; other versions may also be affected. The control is bundled with Microsoft Visual Basic 6.0 and Microsoft Visual FoxPro 8.0 SP1 and 9.0 SP 2.
