## Affected

- Forcepoint Forcepoint One Endpoint (F1E): 23.11

## Description

Forcepoint One DLP Client, version 23.04.5642 (and possibly newer versions), includes a restricted version of Python 2.5.4 that prevents use of the ctypes library. ctypes is a foreign function interface (FFI) for Python, enabling calls to DLLs/shared libraries, memory allocation, and direct code execution. It was demonstrated that these restrictions could be bypassed.
