2X Client TuxClientSystem ActiveX InstallClient() Method Arbitrary MSI Package Installation
High Nessus Plugin ID 58321
SynopsisAn ActiveX control on the remote Windows host could allow installation of arbitrary programs.
DescriptionThe version of the TuxClientSystem ActiveX control, part of the 2X Client, installed on the remote Windows host is earlier than 10.1 Build 1239. As such, its 'InstallClient()' method reportedly accepts a URL to an MSI package and allows installation of an application without explicit user approval.
If an attacker can trick an administrator on the affected system into viewing a malicious HTML document, he could leverage this issue to install an arbitrary application on the system.
SolutionUpgrade to 2X Client 10.1 Build 1239 as that is reported to address the vulnerability.
