CVE-2025-20122
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 Catalyst SD-WAN Manager, formerly Cisco SD-WAN vManage, could allow an authenticated, local attacker to gain privileges of the root user on the underlying operating system. This vulnerability is due to insufficient input validation. An authenticated attacker with read-only privileges on the SD-WAN Manager system could exploit this vulnerability by sending a crafted request to the CLI of the SD-WAN Manager. A successful exploit could allow the attacker to gain root privileges on the underlying operating system.
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 · moderate confidenceLocal privilege escalation vulnerability in Cisco Catalyst SD-WAN Manager CLI where insufficient input validation allows an authenticated attacker with read-only privileges to execute crafted requests that grant root access on the underlying operating system.

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 installed Cisco Catalyst SD-WAN Manager versionAccess the SD-WAN Manager administration interface or use the CLI command 'show version' to retrieve the installed software version.Affected if The installed version matches any of these: 17.2.4, 17.2.5, 17.2.6, 17.2.7, 17.2.8, 17.2.9, 17.2.10, 18.2.0, 18.3.0, 18.3.1, 18.3.1.1, or 18.3.3
-
Verify CLI access is enabledConfirm that the SD-WAN Manager CLI interface is accessible and active. Check the administration settings to see if CLI access is permitted for users.Affected if CLI access is enabled and reachable on the system
-
Confirm read-only user accounts existReview the user account configuration to identify any accounts with read-only privileges. Use the user management interface or CLI command to list all user roles and privilege levels.Affected if One or more read-only user accounts are configured in the system
-
Check for recent privilege escalation indicatorsReview CLI command logs and system audit trails for unusual commands or requests from read-only users that may indicate exploitation attempts. Look for commands that modify system permissions or access elevated functions.Affected if Audit logs show read-only users executing commands outside their intended privilege scope, or evidence of unauthorized root access attempts
Your environment is affected if the installed Cisco Catalyst SD-WAN Manager version matches any of the listed affected versions AND the CLI interface is accessible to authenticated users with read-only privileges.

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.
dbcve · scopedApply the Cisco patch/upgrade for CVE-2025-20122 when released; until then, limit CLI access to only necessary personnel and monitor for suspicious CLI activity.
Later 17.x release (17.3.x or later) as specified in Cisco's official security advisory for CVE-2025-20122
- 1. Verify current Cisco Catalyst SD-WAN Manager version by running: `show version` in the CLI
- 2. Confirm affected versions (17.2.4, 17.2.5, 17.2.6, 17.2.7) are in use before proceeding
- 3. Review Cisco release notes and security advisories at sec.cloudapps.cisco.com for the specific fixed release for CVE-2025-20122
- 4. Schedule a maintenance window as upgrade requires system downtime
- 5. Perform a complete backup of the SD-WAN Manager configuration and database
- 6. Follow Cisco's standard upgrade procedure: transfer the upgrade file to the device, run `request system software install <file>` or equivalent CLI command
- 7. After upgrade completes, verify the new version is installed with `show version`
- 8. Validate that root privilege escalation no longer works from read-only authenticated CLI access
