CVE intelligence and bounded remediation

CVE-2020-3152 — Cisco Connected Mobile Experiences security vulnerability

High CVSS 7.2

A vulnerability in Cisco Connected Mobile Experiences (CMX) could allow an authenticated, local attacker with administrative credentials to execute arbitrary commands with root privileges. The vulnerability is due to improper user permissions that are configured by default on an affected system. An attacker could exploit this vulnerability by sending crafted commands to the CLI. A successful exploit could allow the attacker to elevate privileges and execute arbitrary commands on the underlying operating system as root. To exploit this vulnerability, an attacker would need to have valid administrative credentials.

Matched remediation archetype

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.
