Multiple local privilege escalation vulnerabilities in Proxifier for Mac
------------------------------------------------------------------------
Yorick Koster, April 2017

Abstract
------------------------------------------------------------------------
Multiple local privileges escalation vulnerabilities were found in the
KLoader binary that ships with Proxifier. KLoader is responsible for
loading a Kernel Extension (kext). KLoader is installed setuid root, it
accepts one or two command line arguments that are used in a number of
system commands. These arguments are used in an insecure manner allowing
a local attacker to elevate its privileges. In addition, the environment
is not properly sanitized, which also introduces an possibility to run
arbitrary commands with elevated privileges.

------------------------------------------------------------------------
Tested versions
------------------------------------------------------------------------
These issues were successfully verified on Proxifier for Mac v2.18.

------------------------------------------------------------------------
Fix
------------------------------------------------------------------------
Proxifier v2.19 was released that addresses these issues.
