Original Release date: 21 Jan 2015 | Last revised: 21 Jan 2015

Overview

The iPass Open Mobile Windows Client versions 2.4.4 and earlier contains a remote code execution vulnerability.

Description

CWE-94: Improper Control of Generation of Code ('Code Injection')

The iPass Open Mobile Windows Client versions 2.4.4 and earlier utilizes named pipes for interprocess communication. One of the subprocesses spawned by the client runs with SYSTEM privileges. An authenticated user can register arbitrary DLL files, including ones located at UNC paths, by sending a specially-crafted unicode string to this subprocess to one of the named pipes. The DllMain function in the specified DLL file will then execute with SYSTEM privileges.

Impact

A remote, authenticated user may be able to execute arbitrary code with SYSTEM privileges.

Solution

Apply an Update

Affected users should update to version 2.4.5.
