CVE-2025-34025
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 · uneditedThe Versa Concerto SD-WAN orchestration platform is vulnerable to an privileges escalation and container escape vulnerability caused by unsafe default mounting of host binary paths that allow the container to modify host paths. The escape can be used to trigger remote code execution or direct host access depending on the host operating system configuration.This issue is known to affect Concerto from 12.1.2 through 12.2.0. Additional versions may be vulnerable.
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 confidenceVersa Concerto SD-WAN orchestration platform versions 12.1.2 through 12.2.0 contain a container escape vulnerability where unsafe default mounting of host binary paths into containers allows an attacker with container access to modify host paths, achieving privilege escalation to the host and potentially remote code execution.

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 Versa Concerto installationLocate and inspect the Versa Concerto SD-WAN orchestration platform installation in your environment. Check for processes named 'concerto' or services running on typical Versa SD-WAN management ports.Affected if The system runs Versa Concerto SD-WAN orchestration platform
-
Determine installed Versa Concerto versionCheck the installed version of Versa Concerto using command 'versa --version' or inspect the package/software inventory. Compare against the fixed version 12.2.1.Affected if The installed version is earlier than 12.2.1 (the patched release)
-
Inspect container runtime configurationExamine Docker or container runtime configuration files (docker-compose.yml, container manifests) for volume mount definitions that bind host paths, particularly host binary directories like /usr/bin, /bin, /sbin, or /usr/local/bin.Affected if Container configurations contain unsafe host path mounts (bind mounts to host binary directories)
-
Review container mount permissionsInspect active container mount configurations using 'docker inspect <container_id>' or 'podman inspect <container_id>' to identify mounted host paths and their read/write permissions.Affected if Containers have writable mounts to host binary paths such as /usr/bin or /sbin
The environment is affected if Versa Concerto SD-WAN orchestration is running with a version prior to 12.2.1 AND container configurations expose host binary directories as writable mounts.
Generated from the published advisory. Verify against your own configuration.
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 dataRemediate by removing or restricting unsafe host path mounts from container configurations, implementing least-privilege container runtime settings, and applying vendor-provided patches for affected versions.
