RealNetworks RealGames StubbyUtil.ShellCtl.1 ActiveX Control
(InstallerDlg.dll v2.6.0.445) Multiple Remote Commands Execution
and Code Execution Vulnerabilities
tested against Internet Explorer 9, Vista sp2
download url: http://www.gamehouse.com/
background:
When choosing to play with theese online games ex. the game called
"My Farm Life" (see url: http://www.gamehouse.com/download-games/my-farm-life )
you download an installer called GameHouse-Installer_am-myfarmlife_gamehouse_.exe
This setup program installs an ActiveX with the following settings:
CLSID: {80AB3FB6-9660-416C-BE8D-0E2E8AC3138B}
Progid: StubbyUtil.ShellCtl.1
Binary Path: C:\Program Files\RealArcade\Installer\bin\InstallerDlg.dll
Safe For Initialization (Registry): True
Safe For Scripting (Registry): True
This control is safe for scripting and safe for initialization,
so Internet Explorer will allow scripting of this control from
remote.
vulnerability:
This control has four methods implemented insecurely:
ShellExec() -> allows to launch arbitrary commands
ShellExecRunAs() -> allows to launch arbitrary commands
CreateShortcut() -> allows to create arbitrary executable files inside the automatic
startup folders
CopyDocument() -> allows to copy arbitrary executable files from a remote
network share to local folders, ex. automatic startup folders
other attacks are possible including information disclosure and file deletion,
