CISA KEV Alert: Ivanti EPMM Code Injection Under Active Exploitation — 2026-04-10

Ivanti EPMM Zero-Day Exploitation

[INTEL_REF: KEV-2026-0410] CISA KEV Intelligence Briefing — April 10, 2026

CLASSIFICATION: HIGH PRIORITY — ACTIVE EXPLOITATION CONFIRMED

The Cybersecurity and Infrastructure Security Agency (CISA) has escalated CVE-2026-1340 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active in-the-wild exploitation targeting enterprise Mobile Device Management infrastructure. This vulnerability in Ivanti Endpoint Manager Mobile (EPMM) represents a critical threat vector for any organization managing corporate mobile fleets — and the 24-hour remediation window CISA imposed underscores just how severe this exploitation activity has become.

Ivanti's MDM platform is deployed by thousands of enterprises, government agencies, and healthcare institutions globally. When MDM infrastructure is compromised, attackers gain an unprecedented vantage point — the ability to reach every managed device, push malicious configuration profiles, intercept communications, and establish persistent persistence across an entire mobile fleet. This is not a theoretical risk. CISA's KEV designation means adversaries are actively using this exact flaw right now.

CVE-2026-1340: Technical Anatomy

Vulnerability: Code Injection in Ivanti Endpoint Manager Mobile (EPMM) CVSSv3 Score: 9.8 Critical Attack Vector: Network, pre-authentication — no credentials required CWE: CWE-94 (Improper Control of Generation of Code)

How the Exploit Works

Ivanti EPMM exposes a web-accessible administrative API that processes inbound requests for device enrollment, policy synchronization, and configuration delivery. CVE-2026-1340 is a code injection flaw in the request parsing layer — specifically in how certain API parameters are handled before being passed to a backend processing component.

An unauthenticated attacker sends a crafted HTTP request to the exposed EPMM portal (typically TCP/443 or TCP/8443). The malicious payload embeds OS-level commands or script syntax into a parameter field that the application processes without adequate sanitization. Because the EPMM service runs with elevated system privileges to perform MDM operations, the injected code executes in the context of the service account — which in most deployments has administrative access to the underlying server and the ability to communicate with every enrolled device.

The exploitation chain unfolds as follows:

Initial access — Attacker identifies exposed EPMM instance via Shodan, Censys, or direct reconnaissance
Injection delivery — Specially crafted POST request to vulnerable API endpoint with injected payload
Server-side execution — Application processes the injection without sanitization, executes attacker-controlled commands
Persistence establishment — Attacker installs backdoor, creates rogue admin account, or deploys web shell
Fleet lateral movement — Using MDM authority, attacker pushes malicious profiles or exfiltrates device certificates from enrolled endpoints

Why MDM Compromise Is Catastrophic

MDM servers are not ordinary application servers. They are the nerve center of your mobile fleet. A compromised MDM can:

Push silent application installs to every enrolled iOS, Android, and Windows device — no user interaction required
Intercept email and calendar via ActiveSync configuration hijacking
Extract VPN certificates stored in managed device profiles
Wipe devices or lock them with ransomware-style messages
Access Wi-Fi credentials from pushed network profiles
Enumerate active user sessions and harvest directory credentials

This single server compromise effectively becomes a beachhead for attacking your entire workforce, not just the server itself.

Enterprise Impact Assessment

Who Is at Highest Risk

Organizations with Ivanti EPMM (formerly MobileIron Core) internet-facing deployments are the primary targets. Based on Shodan telemetry, over 3,200 EPMM portals remain publicly accessible as of this writing. High-risk sectors include:

Government agencies — Ivanti EPMM is widely deployed in federal and state government to manage classified mobile endpoints. BOD 22-01 makes remediation legally binding for federal entities.
Healthcare — HIPAA-regulated mobile workforces where device management encompasses patient data access
Financial services — Trading floor and executive mobile fleets with access to sensitive systems
Defense contractors — Managed devices with access to CUI and controlled technical data

Ransomware Campaign Nexus

CISA's KEV catalog notes no confirmed ransomware campaign use for this specific CVE at time of publication, but the exploitation profile — unauthenticated RCE on widely-deployed enterprise infrastructure — closely mirrors TTPs used by Cl0p, LockBit, and nation-state affiliated groups who have historically targeted MDM and network management platforms as pivot points for broad enterprise compromise.

The 24-hour remediation window CISA imposed (due date: April 11, 2026) signals that threat intelligence indicates extremely active exploitation with observed ransomware staging activity.

FLLC Operational Playbook

Immediate Actions (0–4 Hours)

Identify all EPMM instances — Run asset discovery across your network for EPMM servers. Check for MobileIron Core version strings in your CMDB.
Assess internet exposure — Determine if any EPMM admin interfaces are reachable from the public internet. If yes, immediately restrict access to VPN-only via firewall rule or WAF.
Apply Ivanti's emergency patch — Download and apply the security update from Ivanti's security advisory page. Verify patch integrity using the published SHA-256 hash before applying.
Review admin accounts — Audit all EPMM administrator accounts for unauthorized additions in the past 30 days.
Search for web shells — Scan EPMM server directories for newly created .jsp, .php, .aspx, and .sh files using: find / -newer /etc/passwd -name '*.jsp' 2>/dev/null

Detection (4–24 Hours)

Correlate SIEM logs — Look for anomalous POST requests to /mifs/, /api/v1/, or /devicemanagement/ endpoints with unusual parameter lengths or special characters.
Review device enrollment logs — Identify any new device enrollments that occur outside of business hours or from unusual geographic locations.
Check for LOLBin execution — Hunt in EDR telemetry for curl, wget, python, bash, powershell spawning from the EPMM service process.
Validate all pushed profiles — Review every MDM configuration profile deployed in the last 7 days for unauthorized changes.
Notify enrolled users — If compromise is confirmed, proactively notify device users that their managed devices may have received unauthorized configuration changes.

If Compromised

Isolate the server immediately — Pull the EPMM server from the network. Do not attempt live forensics without isolation.
Revoke all device enrollment certificates — Re-enroll all devices after rebuilding the server from a known-good image.
Rotate all credentials — Any credential cached on managed devices or in the EPMM credential store must be rotated.
File CISA report — Federal entities are required to report exploitation under CIRCIA reporting requirements.
