TITLE

Juniper Networks IVE client ActiveX control buffer overflow

DESCRIPTION

Buffer overflow in JuniperSetupDLL.dll, loaded from JuniperSetup.ocx by the Juniper SSL-VPN Client when accessing a Juniper NetScreen IVE device running IVE OS before 4.2r8.1, 5.0 before 5.0r6.1, 5.1 before 5.1r8, 5.2 before 5.2r4.1, or 5.3 before 5.3r2.1, allows remote attackers to execute arbitrary code via a long argument in the ProductName parameter. Juniper SSL-VPN Client ActiveX control is prone to a buffer-overflow vulnerability. The software fails to perform sufficient bounds-checking of user-supplied input before copying it to an insufficiently sized memory buffer. Invoking the object from a malicious website may trigger the condition. If the vulnerability were successfully exploited, this would corrupt process memory, resulting in arbitrary code execution. Juniper's SSL VPN series products can provide users with secure remote access services. JuniperSetupDLL.dll is loaded from the JuniperSetup.ocx ActiveX control. If the following super long string is specified in the ProductName parameter, a stack overflow will be triggered in the JuniperSetupDLL.dll function: --- object classid=\"clsid: E5F5D008-DD2C-4D32-977D-1A0ADF03058B\" id= NeoterisSetup codebase=\"path_to_JuniperSetup.cab#version=1,0,0,3\" > ..... ---PARAM NAME=\"ProductName\" VALUE=\"AAAAAAA (long \'\'A\ '\')\" > ..... script language=javascript NeoterisSetup.startSession(); end script The vulnerable function is as follows: .text: 04F15783 ; int __stdcall sub_4F15783_ilvdlp(char *szProductName, LPCSTR lpValueName, LPBYTE lpData, LPDWORD lpcbData) .text: 04F15783 sub_4F15783_ilvdlp proc near .text: 04F15783 .text: 04F15783 SubKey = byte ptr -10Ch .text: 04F15783 Type = dword ptr -8 .text: 04F15783 hKey = dword ptr -4 ... This can be exploited to cause a stack-based buffer overflow when the control is instantiated with an overly long "ProductName" parameter. tricked into visiting a malicious web site. The vulnerability has been reported in versions 1.x through 5.x. SOLUTION: Update to IVE software version 5.3r2.1, 5.2r4.1, 5.1r8, 5.0r6.1, or 4.2r8.1.
