About this tag
CVE-2025-4428 is a remote code execution vulnerability in Ivanti Endpoint Manager Mobile (EPMM) that, when chained with CVE-2025-4427 (an authentication bypass), allows unauthenticated attackers to deploy malicious listeners and web shells within Tomcat. This enables persistent backdoor access, data exfiltration, and lateral movement. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has released a Malware Analysis Report detailing the malware and indicators of compromise (IOCs) associated with active exploitation. IT teams running on-premises mobile device management (MDM) should prioritize patching and review the MAR for defensive guidance.
