Ivanti Sentry OS Command Injection (CVE-2026-10520)

Historical catalog analysis: CISA added this entry on June 11, 2026. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2026-10520 is an OS command injection vulnerability (CWE-78) identified in Ivanti Sentry (formerly MobileIron Sentry). The flaw allows a remote, unauthenticated attacker to execute arbitrary commands with root-level privileges on the affected appliance.

Exposure and applicability

This vulnerability does not affect all deployments equally. Based on available data, exploitability is contingent upon two primary conditions:
1. Deployment State: The Sentry appliance must be in an “unmanaged state.”
2. Network Reachability: The endpoints must be externally reachable by a remote actor.

Organizations utilizing mTLS with EPMM or those employing restricted HTTPS access via Neurons for MDM may have these interfaces inaccessible to external actors, which alters the exposure profile of the asset.

Remediation priorities

Our analysis suggests that remediation should be prioritized based on the intersection of management state and network visibility. We recommend the following priority sequence:

1. Immediate Isolation: Identify any Sentry appliances in an unmanaged state that are exposed to the public internet. These assets represent the highest risk for root-level compromise.
2. Configuration Hardening: Transition appliances from an unmanaged state to a managed state or implement the supported access restrictions (mTLS with EPMM or Neurons for MDM) to block external access to the vulnerable interfaces.
3. Vendor Mitigation: Apply official vendor mitigations as specified in the security advisory to address the underlying command injection flaw.

How to validate remediation

Verification must go beyond a simple version check, as the vulnerability’s exploitability depends on the appliance state and network configuration. To verify that exposure has been reduced, defenders should:
* Confirm State: Verify through administrative consoles or configuration files that the appliance is no longer in an “unmanaged state.”
* Validate Access Control: Perform a network-level verification to ensure that HTTPS interfaces are not reachable from external, unauthorized networks. If mTLS or Neurons for MDM is implemented, verify that requests without valid certificates or authorized paths are rejected at the edge.
* Verify Patch Application: Confirm the application of vendor-supplied mitigations according to official documentation.

Limits and open questions

While the entry path involves unmanaged states and external reachability, it remains unknown if this vulnerability has been utilized in known ransomware campaigns. Additionally, while restricting access via mTLS or Neurons for MDM reduces the likelihood of external exploitation, these are compensating controls; they do not remove the underlying vulnerability from the software itself. Residual risk remains if an attacker gains internal network access and can reach the unmanaged interface.
