MSIE Xunlei Thunder PPlayer ActiveX BO

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 buffer overflow vulnerability in Xunlei Thunder PPLAYER.DLL_1_WORK ActiveX control.

Additional Information

Xunlei Thunder PPlayer ActiveX Control is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. This issue affects the 'FlvPlayerUrl' method of the 'PPlayer.XPPlayer' class.

The ActiveX control is identified by CLSID: F3E70CEA-956E-49CC-B444-73AFE593AD7F and uses the 'pplayer.dll_1_word' DLL.

An attacker can exploit this issue by enticing an unsuspecting user to view a malicious HTML page.

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.
