DESCRIPTION:
Andrea Micalizzi has discovered a vulnerability in 2X Client
TuxClientSystem ActiveX Control, which can be exploited by malicious
people to compromise a user's system.

The vulnerability is caused due to the "InstallClient()" method of
the TuxClientSystem ActiveX control (TuxClientSystem.dll) allowing to
install an application without a user's approval. This can be
exploited to install an arbitrary application by supplying a MSI
package's URL to the method.

Successful exploitation allows execution of arbitrary code, but
requires tricking an administrative user into viewing a malicious web
page.

The vulnerability is confirmed in version 10.1 Build 1224. Other
versions may also be affected.

SOLUTION:
Update to version 10.1 Build 1239.

PROVIDED AND/OR DISCOVERED BY:
Andrea Micalizzi (rgod) via Secunia.
