CVE-2020-3213 — Cisco Ios Xe security vulnerability

High CVSS 7.2

A vulnerability in the ROMMON of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to those of the root user of the underlying operating system. The vulnerability is due to the ROMMON allowing for special parameters to be passed to the device at initial boot up. An attacker could exploit this vulnerability by sending parameters to the device at initial boot up. An exploit could allow the attacker to elevate from a Priv15 user to the root user and execute arbitrary commands with the privileges of the root user.

Matched remediation archetype

General vulnerability remediation

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

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
