Foxit PhantomPDF ConvertToPDF Arbitrary File Write Remote Code Execution Vulnerability

by

EIP-884255a1

The vulnerability exists within an RPC interface listening on TCP port 6000, exposed by Foxit PhantomPDF. The ConvertToPDF method of the Creator object does not properly validate the bstrDestPathName argument, allowing 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 vulner- ability to achieve remote code execution.

Foxit PhantomPDF ConnectedPDF DocSearch_Locator_Table SQL Injection Remote Code Execution Vulnerability

by

EIP-68b878c6

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”.
