AI-suggested

Until an official patch is released by Foxit, organizations should implement multiple layers of mitigation. First, restrict the use of Foxit PDF Reader version 2023.2.0.21408 and consider temporarily switching to alternative PDF readers with no known vulnerabilities. Employ application control or whitelisting to prevent execution of untrusted or suspicious PDF files. Enhance email and web filtering to block or quarantine PDFs from untrusted sources, especially those containing AcroForms. Educate users about the risks of opening unsolicited or unexpected PDF attachments and links. Enable sandboxing or run Foxit PDF Reader with least privilege to limit the impact of potential exploitation. Monitor endpoint detection and response (EDR) tools for unusual behavior related to Foxit processes. Finally, maintain up-to-date backups and incident response plans to quickly recover from any compromise. Once Foxit releases a patch, prioritize its deployment across all affected systems.

Description

Foxit PDF Reader AcroForm Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of Doc objects in AcroForms. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22642.
