Microsoft Internet Explorer ActiveX kill bit settings can be bypassed
| ie-activex-killbit-bypass (24379) |  Medium Risk |
Description:
Microsoft Internet Explorer could allow a remote attacker to bypass the kill bit settings for ActiveX controls. Kill bits can be set in the system registry and are used to disable the initiation of a COM object in Internet Explorer. A remote attacker could create a malicious Web page containing specially crafted HTML which would cause the kill bit settings for ActiveX controls to be bypassed by Internet Explorer. This vulnerability could be exploited to use a disabled ActiveX control to execute arbitrary code on a victim's system, if the attacker could persuade the victim to visit the malicious Web page.
Platforms Affected:
- Microsoft, Internet Explorer 5.01 SP2
- Microsoft, Internet Explorer 5.01 SP3
- Microsoft, Internet Explorer 5.01 SP4
- Microsoft, Internet Explorer 5.5
- Microsoft, Internet Explorer 6 SP1
