Juniper SSL-VPN IVE JuniperSetupDLL.dll ActiveX Control Buffer Overflow

Juniper SSL-VPN IVE JuniperSetupDLL.dll ActiveX Control Buffer Overflow
Posted Nov 26, 2009
Authored by patrick | Site metasploit.com

This Metasploit module exploits a stack overflow in the JuniperSetupDLL.dll library which is called by the JuniperSetup.ocx ActiveX control, as part of the Juniper SSL-VPN (IVE) appliance. By specifying an overly long string to the ProductName object parameter, the stack is overwritten.
