CVE-2026-1340: Ivanti Endpoint Manager Mobile (EPMM) Code Injection Vulnerability
Ivanti Endpoint Manager Mobile (EPMM) contains a code injection vulnerability that could allow attackers to achieve unauthenticated remote code execution.
Overview
Ivanti Endpoint Manager Mobile (EPMM) versions through 12.7.0.0 contain a code injection flaw that allows a remote, unauthenticated attacker to execute arbitrary code on the server. No credentials, user interaction, or prior access are required. Ivanti confirmed active exploitation against a limited number of customers at the time of disclosure. Cloud-based Ivanti products, including Ivanti Neurons for MDM, are not affected.
Vulnerability details
Code injection (CWE-94) occurs when an application accepts attacker-controlled input and passes it to an interpreter or execution context without adequate sanitization, causing the runtime to treat that input as code rather than data. In EPMM, the management interface fails to properly validate or neutralize input before it is processed, allowing injected content to be evaluated as executable code by the server. The specific endpoint or parameter carrying the injected payload is not disclosed in available sources.
An attacker with network access to the EPMM management interface sends a crafted, unauthenticated request containing injected code. The server processes that request and executes the attacker-supplied code, yielding full remote code execution with high impact to confidentiality, integrity, and availability. No authentication, elevated privilege, or user interaction is required. The only precondition is that the management interface be reachable over the network and that the instance be running an affected version at or below 12.7.0.0.
Severity and impact
Exploitation status
This vulnerability is confirmed as actively exploited in the wild — it is listed in CISA's Known Exploited Vulnerabilities (KEV) catalog.
Detection and monitoring
- Review EPMM server logs for unexpected or malformed requests to the management interface from external or untrusted source addresses, particularly requests that produce anomalous server-side process activity or error responses inconsistent with normal device management traffic.
- Ivanti published an RPM detection script and indicators of compromise (IoCs) in partnership with NCSC-NL, updated on February 12, 2026. Run this script against any potentially exposed appliance and compare results against the published IoC list before concluding a system is clean.
- Monitor for unexpected child processes spawned by the EPMM application process, or for new files written outside the expected working directories, which may indicate successful code execution following exploitation.
Remediation
Additional hardening
- Upgrade EPMM to version 12.6.1.1, 12.7.0.1, or 12.8.0.1 depending on the installed release line. Appliances updated to one of these versions do not require the interim RPM package released in January 2026. See References for the vendor advisory.
- Restrict network access to the EPMM management interface to known, trusted IP ranges using perimeter controls or host-based firewall rules. Reducing the interface's exposure to untrusted networks directly limits the attacker's ability to reach the vulnerable endpoint.
- If immediate patching is not possible, consider taking the management interface offline or placing it behind a VPN or zero-trust access gateway to prevent unauthenticated external requests from reaching it.
- Audit EPMM appliances for signs of compromise using Ivanti's published detection script and IoC list before returning patched systems to production, as exploitation was confirmed in the wild prior to disclosure.

Frequently asked questions
Does CVE-2026-1340 affect my FedRAMP authorization?
If Ivanti Endpoint Manager Mobile (EPMM) runs inside your authorization boundary, yes. CVE-2026-1340 is listed on CISA's Known Exploited Vulnerabilities (KEV) catalog, and its remediation deadline of April 11, 2026 has already passed. For a FedRAMP-authorized service, an unpatched KEV is a finding your assessor and sponsoring agency can see. At this point, the finding is overdue: you either close it out now or formally document the mitigation and the delay.
How does Knox help me handle CVE-2026-1340?
Knox does not patch your software. Remediating Ivanti Endpoint Manager Mobile (EPMM) is your responsibility under the FedRAMP shared-responsibility model. What Knox provides is the pre-authorized, single-tenant boundary to remediate within, plus continuous compliance monitoring and audit-artifact coverage that support your documentation for the next assessment. Applying the fix is yours to own; maintaining a defensible compliance posture while you do it is not something you have to manage alone.
How does Knox's monitoring help with vulnerabilities like this?
Knox's automated continuous monitoring platform watches your environment for newly disclosed vulnerabilities and compliance issues on an ongoing basis. For a case like CVE-2026-1340, that means exposure surfaces during continuous monitoring rather than waiting for an assessor to flag it at the next scheduled review.
How do I get FedRAMP authorized with Knox?
Knox runs a FedRAMP-as-a-Service platform. It gives SaaS vendors a pre-authorized cloud boundary on AWS, Azure, and GCP. Your application inherits 60-80% of the required security controls. You reach FedRAMP authorization in about 90 days for roughly 90% less than the traditional $3.5M path. Book a meeting and Knox will map your path to authorization.
CVE-2026-1340's remediation deadline of April 11, 2026 has passed. What happens now?
If CVE-2026-1340 remains unremediated, it is already a Plan of Action and Milestones (POA&M) item. A growing POA&M list is what turns a routine continuous-monitoring review into a difficult conversation with your sponsoring agency. Closing the finding out now and documenting why the deadline was missed is what keeps your authorization standing and the agency relationship intact.
