What is CVE-2011-2883?
The NSEPA.NsepaCtrl.1 ActiveX control in the Citrix Access Gateway allows attackers to exploit a flaw in the DLL validation process. By checking only the certificate subject rather than the signature, it becomes possible for a man-in-the-middle attacker to execute arbitrary code by referencing malicious DLLs through specially crafted HTTP header data. This exposes systems to significant security risks if not properly mitigated.
