VAR-201107-0297
Vulnerability from variot - Updated: 2023-12-18 12:22Stack-based buffer overflow in the NSEPA.NsepaCtrl.1 ActiveX control in nsepa.ocx in Citrix Access Gateway Enterprise Edition 8.1 before 8.1-67.7, 9.0 before 9.0-70.5, and 9.1 before 9.1-96.4 allows remote attackers to execute arbitrary code via crafted HTTP header data. Citrix Access Gateway is a universal SSL VPN device. Attackers may exploit these issues by enticing an unsuspecting victim to view a malicious webpage. Citrix Access Gateway Plug-in versions prior to 8.1-67.7, 9.0-70.5, and 9.1-96.4 are vulnerable; other versions may also be affected
