Ivanti Endpoint Manager Mobile — Unauthenticated Remote Code Execution
Product: Ivanti Endpoint Manager Mobile (EPMM)
Component(s) impacted: In-House Application Distribution and Android File Transfer Configuration services
Issue type: Pre-authentication code injection leading to remote code execution
Exposure: Internet-facing EPMM instances
Overview
Two critical vulnerabilities, CVE-2026-1281 and CVE-2026-1340, affect Ivanti Endpoint Manager Mobile. The flaws allow unauthenticated remote code execution by sending specially crafted HTTP requests to exposed EPMM endpoints. Because no credentials are required and the vulnerable services are commonly reachable over the network, the overall risk is considered critical.
When exploited, arbitrary operating-system commands may be executed with the privileges of the EPMM service account. This can result in full system compromise, persistence, data theft, and lateral movement.
Affected Versions
- Ivanti Endpoint Manager Mobile versions prior to Ivanti’s January 2026 security updates
- Both on-premises and virtual/appliance deployments are impacted if the vulnerable endpoints are exposed
Vulnerability Details
Improper input handling is present in specific EPMM web endpoints used for:
- In-House application distribution
- Android file transfer configuration
User-supplied request parameters are not sufficiently sanitized before being passed into command execution contexts. As a result, shell metacharacters and command sequences may be interpreted by the underlying system shell.
Because authentication checks are not enforced for these endpoints, exploitation is possible before login, making the attack both simple and high impact.
Exploitation Scenario
- An Internet-reachable EPMM instance is identified by an attacker.
- A crafted HTTP request is sent to a vulnerable endpoint containing shell syntax or command injection payloads.
- The request is processed without proper validation.
- Embedded commands are executed by the system shell.
- Follow-on actions may include payload download, reverse shell creation, persistence mechanisms, or credential access.
Impact
If successfully exploited, the following outcomes are possible:
- Remote command execution on the EPMM server
- Installation of malware or web shells
- Creation of persistent backdoors
- Unauthorized access to managed mobile device data
- Pivoting into internal networks
- Full compromise of the MDM environment

Proof-of-Concept and Exploitation Notes
- Public proof-of-concept examples and scanning templates exist and are widely accessible.
- These PoCs demonstrate command injection through crafted HTTP requests.
- Real-world exploitation patterns show attackers chaining command execution with payload download and persistence.
Detection and Monitoring Guidance
Primary Indicators of Compromise
- HTTP requests to EPMM endpoints containing:
- Shell metacharacters (
;,&&,`,|,$() - Suspicious command strings (
wget,curl,nc,bash,sh,python)
- Shell metacharacters (
- Unusual or long URL query strings targeting EPMM services
- Execution of shell interpreters or network utilities spawned by the EPMM service
- Unexpected outbound network connections from the EPMM host
- New or modified files in temporary or application directories
Recommended Log Sources
Monitoring should be focused on:
- EPMM web access logs (HTTP request paths and parameters)
- Application logs for the EPMM services
- Operating system process creation logs
- File integrity and filesystem monitoring
- Firewall, proxy, and IDS/IPS logs
- Endpoint Detection and Response (EDR) telemetry on EPMM servers
Detection Logic
Web Log Analysis
- Flag requests to EPMM endpoints containing shell syntax or command keywords.
- Correlate suspicious requests with process creation events.
Process Monitoring
- Alert when the EPMM service account spawns:
/bin/bash,/bin/shcurl,wget,nc- Scripting runtimes such as Python or Perl
Network Monitoring
- Detect outbound connections from EPMM servers to unknown or external IP addresses shortly after suspicious web requests.
MITRE ATT&CK Mapping
- Initial Access: Exploit Public-Facing Application (T1190)
- Execution: Command and Scripting Interpreter (T1059)
- Persistence: Create or Modify System Process / Scheduled Task
- Lateral Movement: Use of compromised credentials or remote services
Mitigation and Hardening
Immediate Actions
- Apply Ivanti’s official security update without delay.
- Restrict external access to EPMM management endpoints.
- Review historical logs for signs of exploitation.
Compensating Controls
- Enforce IP allow-listing for EPMM administrative interfaces.
- Deploy WAF rules to block suspicious shell patterns.
- Increase logging verbosity and alerting sensitivity.
- Limit outbound network access from EPMM servers.

Final Takeaway
These vulnerabilities represent a high-risk attack surface due to pre-authentication access and direct command execution. Unpatched systems should be considered exposed and potentially compromised. Patch deployment, log review, and continuous monitoring are strongly advised.
