CVE-2024-20389 — Cisco Crosswork Network Services Orchestrator security vulnerability

High CVSS 7.8

A vulnerability in the ConfD CLI and the Cisco Crosswork Network Services Orchestrator CLI could allow an authenticated, low-privileged, local attacker to read and write arbitrary files as root on the underlying operating system. This vulnerability is due to improper authorization enforcement when specific CLI commands are used. An attacker could exploit this vulnerability by executing an affected CLI command with crafted arguments. A successful exploit could allow the attacker to read or write arbitrary files on the underlying operating system with the privileges of the root user.

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.
