Security readout for executives and security teams
CVE-2018-9958 is a Foxit Reader flaw that can let an attacker run code if a user opens a malicious file or visits a malicious page. The known affected version is Foxit Reader 9.0.1.1049. It is not listed as CISA KEV, but public exploit references exist. Exposure is most likely on endpoints still running Foxit Reader 9.0.1.1049, especially where users handle external PDFs or browse untrusted content. The source bundle does not identify other affected Foxit products or versions. Treat this as a high-priority legacy endpoint risk if Foxit Reader 9.0.1.1049 exists in the environment. Business urgency is driven by code execution impact and public exploit references, tempered by required user interaction and no KEV evidence. Mitigation focus: Inventory endpoints for Foxit Reader 9.0.1.1049.; Check Foxit security bulletins for vendor-confirmed fixed versions or guidance.; Upgrade, remove, or isolate affected Foxit Reader installations according to vendor guidance..
