Loading vulnerability…
The LaunchObj ActiveX control in launcher.dll, used by Symantec AppStream Client versions 5.2.x before 5.2.2 SP3 MP1, fails to properly validate downloaded files. This flaw exists in the installAppMgr method and potentially other methods, allowing remote attackers to execute arbitrary code by supplying malicious input to the vulnerable ActiveX control.

This repository contains a single Metasploit module targeting a vulnerability (CVE-2008-4388) in the Symantec AppStream Client 5.x, specifically the LaunchObj ActiveX control (launcher.dll 5.1.0.82). The exploit works by serving a malicious HTML page with embedded JavaScript that invokes the vulnerable ActiveX control's 'installAppMgr' method, causing the victim's browser to download and execute an arbitrary EXE payload. The payload is generated and served by the Metasploit framework. The module is written in Ruby and leverages Metasploit's HTTP server and EXE generation capabilities. The main attack vector is through a browser on a Windows system with the vulnerable ActiveX control installed. The only file in the repository is the exploit module itself, and it is fully operational within the Metasploit framework.
