Initial Access TA0001
T1190Exploit Public-Facing Application×1
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network. The weakness in the system can be a software bug, a temporary glitch, or a misconfiguration.
T1059.004Command and Scripting Interpreter: Unix Shell×1
Adversaries may abuse Unix shell commands and scripts for execution. Unix shells are the primary command prompt on Linux, macOS, and ESXi systems, though many variations of the Unix shell exist (e.g. sh, ash, bash, zsh, etc.) depending on the specific OS or distribution. Unix shells can control every aspect of a system, with certain commands requiring elevated privileges.
CVE-2026-10520 is an unauthenticated OS command injection in Ivanti Sentry (formerly MobileIron Sentry), the EMM/MDM enforcement gateway that proxies email and applications to managed devices and frequently fronts Exchange. The vulnerable endpoint is /mics/api/v2/sentry/mics-config/handleMessage on the MICS admin API (port 8443): ConfigServiceController.handleMessage() accepts XML payloads containing commandexec blocks whose reqandres field is passed unvalidated through ConfigRequestProcessor.handleExecute() into native command execution, yielding root-level RCE with no authentication (watchTowr, 2026-06-10). watchTowr published the technical analysis and a working PoC on 2026-06-10; CVE-2026-10523 is a companion authentication bypass (CWE-288) covered in the same Ivanti advisory (watchTowr, 2026-06-10). No in-the-wild exploitation is confirmed yet, but a same-day public PoC against a pre-auth root RCE on a government-grade MDM gateway sharply compresses the window. Affected: all Sentry before R10.5.2 / R10.6.2 / R10.7.1; patch immediately and restrict the MICS interface (8443) to management IPs in the interim (T1190, T1059.004).
