  # Exploit Title: CCH Wolters Kluwer PFX Engagement <= v7.1 Local Privilege Escalation     # Date: 11/26/14 # Exploit Author: singularitysec@gmail.com # Vendor Homepage: www.cchgroup.com   # Version: PFX Engagement <= v7.1 # Tested on: Windows XP -> Windows 8, 2003, 2008, 2012 # CVE : 2014-9113     Product Affected: CCH Wolters Kluwer PFX Engagement <= v7.1 This vulnerability has been reference checked this against multiple installs. This configuration was identical across all systems and each version encountered. Executables/Services:   Pfx.Engagement.WcfServices PFXEngDesktopService PFXSYNPFTService P2EWinService Attack Detail: The PFX services for engagement install with LOCAL SYSTEM service credentials in the directory C:\PFX Engagement\   [image: Inline image 1]     The executables that are installed, by default, allow AUTHENTICATED USERS to modify, replace or alter the file. This would allow an attacker to inject their code or replace the executable and have it run in the context of the system. [image: Inline image 2] This would allow complete compromise of a machine on which it was installed, giving the process LOCAL SYSTEM access to the machine in question. An attacker can replace the file or append code to the executable, reboot the system or restart the service and it would then compromise the machine. As LOCAL SYSTEM is the highest privilege level on a machine, this allows total control and access to all parts of the system. This affects both the server and workstation builds.   Remediation:   Remove the modify/write permissions on the executables to allow only privileged users to alter the files. Apply vendor patch when distributed.     Vulnerability Discovered: 11/26/2014 Vendor Notified: 11/26/2014 Vendor states this will be patched with next software update.   Website: www.information-paradox.net This vulnerability was discovered by singularitysec@gmail.com.
