HTTP: Citrix Access Gateway Plug-in For Windows 'nsepacom' Unsafe ActiveX Method
This signature detects attempts to use unsafe ActiveX controls in Citrix Access Gateway. 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
The Citrix Access Gateway Plug-in ActiveX control is prone to multiple remote code-execution vulnerabilities because it 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. Citrix Access Gateway Plug-in 9.3.49.5 is vulnerable; other versions may also be affected.
