APP: Citrix Access Gateway Plug-in for Windows nsepacom ActiveX Control Buffer Overflow
This signature detects attempts to exploit a known vulnerability in the Citrix Access Gateway Plug-in for Windows. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the user.
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.
