CVE-2018-25148 — Microhardcorp Ipn4G Firmware security vulnerability

High CVSS 8.8

Microhard Systems IPn4G 1.1.0 contains multiple authenticated remote code execution vulnerabilities in the admin interface that allow attackers to create crontab jobs and modify system startup scripts. Attackers can exploit hidden admin features to execute arbitrary commands with root privileges, including starting services, disabling firewalls, and writing files to the system.

Privilege escalation and unsafe privilege management

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
