Signature Detail

HTTP: Dell Webcam Center CrazyTalk4Native.dll ActiveX

This signature detects attempts to use unsafe ActiveX controls in Dell Webcam Center. An attacker can create a malicious Web site containing Web pages with dangerous ActiveX controls, which if accessed by a victim, allows the attacker to gain control of the victim's client browser.

Extended Description

Dell Webcam Center is prone to multiple stack-based buffer-overflow vulnerabilities because the application fails to perform adequate boundary checks on user-supplied input. Attackers may exploit these issues to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Failed exploit attempts will likely result in denial-of-service conditions.
