AI-suggested

Organizations should immediately verify if they are running the affected Foxit PDF Reader version 2025.1.0.27937 and prioritize upgrading to a patched version once available. Until a patch is released, mitigate risk by restricting local user permissions to prevent unauthorized code execution, especially in directories included in the update service's search path. Implement application whitelisting to prevent loading of unauthorized DLLs or libraries. Employ endpoint detection and response (EDR) solutions to monitor for suspicious local privilege escalation attempts. Additionally, review and harden the update service configuration to ensure it does not load libraries from insecure locations such as user-writable directories. Network segmentation and least privilege principles should be enforced to limit the impact of a compromised workstation. Regularly audit installed software versions and maintain an inventory of applications to quickly identify vulnerable instances.

Description

Foxit PDF Reader Update Service Uncontrolled Search Path Element Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Foxit PDF Reader. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Foxit Reader Update Service. The product loads a library from an unsecured location. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of SYSTEM. Was ZDI-CAN-25709.
