CVE-2022-20716
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to gain escalated privileges. This vulnerability is due to improper access control on files within the affected system. A local attacker could exploit this vulnerability by modifying certain files on the vulnerable device. If successful, the attacker could gain escalated privileges and take actions on the system with the privileges of the root user.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA local privilege escalation vulnerability exists in Cisco SD-WAN Software's CLI due to improper access controls on certain system files. An authenticated local attacker can modify these unprotected files to gain root-level privileges, allowing full system compromise with root access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the Cisco SD-WAN productRun 'show version' or check the system documentation to determine which SD-WAN component is running (vManage, vBond, vEdge, vSmart)Affected if The product is any of: Cisco Catalyst SD-WAN Manager, Cisco SD-WAN Solution, Cisco SD-WAN Vbond Orchestrator, Cisco SD-WAN Vedge Cloud, Cisco SD-WAN Vedge Router, or Cisco SD-WAN Vsmart Controller
-
Determine the software versionExecute 'show version' in the CLI to obtain the installed software version numberAffected if The version falls within these ranges: >= 18.4 and < 20.6.1, OR >= 20.7 and < 20.7.1 (note: some products are affected at ALL versions)
-
Verify local CLI access existsConfirm the system has local CLI access enabled and check for user accounts with CLI login permissionsAffected if Local CLI authentication is enabled and non-privileged user accounts exist on the system
-
Check for unauthorized privilege escalation indicatorsReview system logs and audit files for unusual sudo, su, or file permission changes to system files in /etc or similar directoriesAffected if Evidence exists of file modifications to system configuration files by unexpected users or processes
A system is affected if it runs any Cisco SD-WAN product version within 18.4 to <20.6.1 or 20.7 to <20.7.1, or any version of the fully-affected product line (vManage, vBond, vEdge, vSmart), and has local CLI access available to authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data20.6.120.7.1
Apply the vendor-supplied security patch or upgrade to a fixed version of Cisco SD-WAN Software. Restrict local CLI access to trusted personnel and monitor for unauthorized file modifications.
