The vulnerability exists within the ConnectedPDF service, implemented by the FoxitPhantomConnectedPDFService.exe binary. The service listens for connections on TCP port 44440 on localhost and fails to sanitize input data before using it to construct SQL queries. This allows arbitrary files to be written under the context of the user running PhantomPDF. An attacker can create a specially crafted PDF file that will abuse this vulnerability to achieve remote code execution. Each message has a Type field, denoting the message type. The vulnerability resides in the processing of message type 1004, the handler of which is characterized by string references such as “DocSearch_Locator_Table”.
