Detect Ivanti EPMM Code Injection Exploitation (CVE-2026-1340) in Google Chronicle
Detects exploitation attempts targeting CVE-2026-1340, a code injection vulnerability (CWE-94) in Ivanti Endpoint Manager Mobile (EPMM). This vulnerability is listed in CISA's Known Exploited Vulnerabilities catalog and allows remote attackers to inject and execute arbitrary code via the EPMM management interface. Successful exploitation may lead to full device management compromise, lateral movement, and data exfiltration from enrolled mobile devices.

Data Sources
Required Tables
False Positives & Tuning
- EPMM scripting features or plugin APIs that legitimately accept code-like input
- Authorized penetration testing or red team operations targeting EPMM infrastructure
- Third-party MDM integrations that pass template expressions through EPMM APIs
- URL-encoded payloads from legitimate MDM clients that contain characters triggering injection patterns

Testing Methodology
Validate this detection against 3 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1EPMM API Endpoint Code Injection Pattern Probe
Expected signal: Web server access logs will show POST requests to /mifs/j_spring_security_check and GET requests to /api/v1/configuration/users with URL-encoded injection patterns. Network security appliances should log the requests with high-severity signatures. Host-based EDR should not show process anomalies for a non-successful probe.
- Test 2Simulate Java Process Spawning Shell After EPMM Exploitation
Expected signal: Process creation events showing java spawning /bin/sh as a child process. EDR telemetry should capture the full process tree: [parent] -> java -> sh -> id/hostname/whoami. Command line arguments visible in process creation logs.
- Test 3EPMM Reconnaissance — Unauthenticated API Enumeration
Expected signal: Web access logs showing sequential requests from a single IP to multiple EPMM administrative paths within a short time window. Firewall or IDS/IPS logs may flag the scanning pattern. HTTP response codes (200, 302, 401, 403) visible in logs.
