A critical security flaw in Forcepoint One DLP Client has been disclosed, allowing attackers to bypass vendor-implemented Python<\/a> restrictions and execute arbitrary code on enterprise endpoints.<\/p>\n

The vulnerability, tracked as CVE-2025-14026, undermines the data loss prevention security controls designed to protect sensitive organizational data.<\/p>\n

The Forcepoint One DLP Client<\/a> version 23.04.5642 and potentially subsequent versions shipped with a constrained Python 2.5.4 runtime that deliberately omitted the ctypes foreign function interface (FFI) library.<\/p>\n

This restriction was intended to prevent malicious code<\/a> execution. However, security researcher Keith Lee demonstrated a complete bypass of this protection mechanism.<\/p>\n

Attackers can restore ctypes functionality by transferring compiled ctypes dependencies from another system and applying a version-header patch to the ctypes.pyd module.<\/p>\n

Once patched and correctly positioned on the search path, the previously restricted Python environment successfully loads ctypes.<\/p>\n

Enabling direct invocation of DLLs<\/a>, memory manipulation, and execution of arbitrary shellcode or DLL-based payloads. The vulnerability poses significant risks to enterprise security infrastructure.<\/p>\n

Arbitrary code execution within the DLP client may allow attackers to interfere with or bypass data loss prevention<\/a> enforcement, alter client behavior, or turn off security monitoring functions.<\/p>\n

Because the client operates as a critical security control on enterprise endpoints<\/a>, successful exploitation may substantially reduce the effectiveness of DLP protections and weaken overall system security.<\/p>\n

Forcepoint acknowledged the vulnerability and confirmed that the vulnerable Python runtime has been removed from Forcepoint One Endpoint builds starting with version 23.11, as part of Forcepoint DLP v10.2.<\/p>\n

CERT\/CC advises<\/a> organizations to upgrade to endpoint versions that no longer include python.exe immediately.<\/p>\n

Security teams should prioritize deploying patched versions across all enterprise endpoints to restore DLP protection integrity.<\/p>\n
