CVE-2026-10520

Ivanti Sentry (formerly MobileIron Sentry) contains an OS command injection flaw (CWE-78) that lets a remote, unauthenticated attacker execute operating-system commands with root privileges on the appliance. Exploitation succeeds when the Sentry appliance is in an unmanaged state with its endpoints externally reachable; deployments that enforce mTLS with EPMM or restrict HTTPS access through Ivanti Neurons for MDM keep the interfaces inaccessible to external actors. A successful attacker gains root-level remote code execution, giving full control of the gateway that fronts an organization's mobile device management (MDM) infrastructure. Organizations running unmanaged, internet-exposed Ivanti/MobileIron Sentry appliances are affected. The flaw is being exploited in the wild — CISA added it to the Known Exploited Vulnerabilities catalog on 2026-06-11 (formal CVSS scoring is still pending), EPSS puts the 30-day exploitation probability at 99.9%, no public proof-of-concept is known, and ransomware use is undetermined.

What to do: Inventory all Ivanti/MobileIron Sentry appliances and determine whether they are unmanaged with externally reachable endpoints; apply Ivanti's mitigations in line with CISA KEV and BOD 26-04 timelines, and where a patch is not yet in place, restrict access by enabling mTLS with EPMM or limiting HTTPS access through Ivanti Neurons for MDM. Monitor Ivanti's advisories for fixed versions and review exposed appliances for signs of compromise.
