Foxit Reader 7.0.6.1126 Unquoted Service Path Elevation Of Privilege Vendor: Foxit Software Incorporated Product web page: http://www.foxitsoftware.com Affected version: 7.0.6.1126 and 6.1 Summary: Foxit Reader is a small, lightning fast, and feature rich PDF viewer which allows you to create (free PDF creation), open, view, sign, and print any PDF file. Desc: The application suffers from an unquoted search path issue impacting the service 'FoxitCloudUpdateService' for Windows deployed as part of Foxit Reader. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. A successful attempt would require the local user to be able to insert their code in the system root path undetected by the OS or other security applications where it could potentially be executed during application startup or reboot. If successful, the local user’s code would execute with the elevated privileges of the application.
