Loading vulnerability…
Novell GroupWise contains an unsafe ActiveX control in gwcls1.dll. In GroupWise 8.0 versions before 8.0.3 HP2 and GroupWise 2012 versions before SP1 HP1, remote attackers can supply a pointer argument to the SetEngine method or an XPItem pointer argument to an unspecified method, resulting in arbitrary code execution.

This repository contains a single Metasploit module targeting a remote code execution vulnerability (CVE-2012-0439) in the Novell GroupWise Client's gwcls1.dll ActiveX control. The exploit is delivered via a malicious HTML page served by the Metasploit framework, which triggers the vulnerability when visited using Internet Explorer versions 6 through 9 on Windows XP SP3, Vista, or Windows 7. The module uses JavaScript heap spraying and ROP chains to bypass DEP/ASLR, with special handling for different IE/OS versions. The exploit allows for arbitrary code execution in the context of the browser user and can also leak 4 bytes of memory from an arbitrary address. The payload is fully customizable using Metasploit's payload system. The only file in the repository is a Ruby script structured as a standard Metasploit exploit module, with clear references to the targeted DLL, ActiveX CLSID, and supported environments.
