Exploitation Conditions	No special conditions — remote unauthenticated exploitation against default configurations of Ivanti Endpoint Manager Mobile with network accessibility to vulnerable endpoint.
Impact	CVSS 9.8, EPSS 50.9%. Ivanti EPMM/MobileIron is one of the most deployed enterprise MDM solutions. Compromising the MDM server is a force multiplier: it provides access to every managed mobile device in the organization. Ivanti products have been repeatedly targeted by APT groups (China-nexus, Russia-nexus).
Exploit ScenarioDerived	An attacker exploits the code injection to gain shell access on the EPMM server. They extract device enrollment certificates, VPN configurations, and WiFi credentials for all managed devices. They push a malicious configuration profile to executive devices that installs a surveillance payload, or they extract corporate email credentials stored in managed mail profiles.

Executive ViewAI

Why It Matters

A critical unauthenticated remote code execution vulnerability in Ivanti Endpoint Manager Mobile (CVE-2026-1340, CVSS 9.8) poses an immediate threat to any organization using this platform. Attackers can bypass authentication entirely and gain complete system control without user interaction, creating severe risk of data breach, lateral movement, and operational disruption across mobile device management infrastructure.

Business Impact: Severe

Compensating Controls

Implement network segmentation to restrict access to Ivanti Endpoint Manager Mobile interfaces; deploy Web Application Firewall (WAF) rules to detect/block code injection payloads; disable unnecessary remote management features; enforce strict network access controls and IP whitelisting; increase monitoring and logging for authentication bypass attempts and suspicious code execution; consider temporary service shutdown if business continuity permits; implement runtime application self-protection (RASP) if available. No vendor patch is currently available; prioritize patch release communication from Ivanti.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
