This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader before 9.1 and PhantomPDF before 9.1. 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 processing of specially crafted pdf files with embedded u3d images. Crafted data in the PDF file can trigger an overflow of a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process, a different vulnerability than CVE-2018-5674 and CVE-2018-5676.

Security readout for executives and security teams

CVE-2018-5678 is a remote code execution issue in older Foxit PDF products. A user must open a malicious PDF or visit a malicious page. Successful exploitation could let attacker-supplied code run with the user's privileges. Organizations are most exposed where Foxit Reader or PhantomPDF versions before 9.1 remain installed, especially on workstations that routinely receive external PDFs through email, web downloads, client portals, or document workflows. Treat as high priority for environments with legacy Foxit deployments. The issue is older, but the impact is code execution from document handling, which can still matter on unmanaged or long-lived workstations. Mitigation focus: Upgrade Foxit Reader and PhantomPDF to 9.1 or a later vendor-supported release.; Inventory endpoints for Foxit Reader or PhantomPDF versions earlier than 9.1.; Limit opening externally supplied PDFs on unpatched systems pending remediation..
