CVE-2020-12148
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 command injection flaw identified in the nslookup API in Silver Peak Unity ECOSTM (ECOS) appliance software could allow an attacker to execute arbitrary commands with the privileges of the web server running on the EdgeConnect appliance. An attacker could exploit this vulnerability to establish an interactive channel, effectively taking control of the target system. This vulnerability can be exploited by an attacker with authenticated access to the Orchestrator UI or EdgeConnect UI. This affects all ECOS versions prior to : 8.1.9.15, 8.3.0.8, 8.3.1.2, 8.3.2.0, 9.0.2.0, and 9.1.0.0.
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.

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.
-
Determine ECOS firmware versionAccess the EdgeConnect web UI or use CLI 'show version' command to retrieve the installed ECOS firmware versionAffected if The version displayed falls within any of these ranges: 8.1.x before 8.1.9.15, 8.3.0.x before 8.3.0.8, 8.3.1.x before 8.3.1.2, or 9.0.x before 9.0.2.0
-
Verify web UI accessibilityConfirm the EdgeConnect web management interface is accessible from network locations where untrusted users could operateAffected if The web UI is exposed to network segments with untrusted or unknown users
-
Check nslookup API availabilityLocate the nslookup or DNS lookup function within the web UI under troubleshooting, diagnostics, or network tools sectionsAffected if The nslookup API feature is present and accessible without additional security restrictions
-
Confirm authentication exposureDetermine whether the web UI allows authentication for users who are not explicitly trusted administratorsAffected if Non-administrator or untrusted user accounts can authenticate to the web interface
A user is affected if the EdgeConnect ECOS version is within the vulnerable ranges AND the web UI with nslookup API is accessible to untrusted or unauthorized users.
