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 web interface of the Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to perform command injection and elevate privileges to root. The attacker must authenticate with valid administrator credentials. Affected Products: Cisco AsyncOS Software 10.0 and later for WSA on both virtual and hardware appliances. More Information: CSCvd88862. Known Affected Releases: 10.1.0-204. Known Fixed Releases: 10.5.1-270 10.1.1-235.
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 command injection vulnerability in the Cisco Web Security Appliance web interface allows an authenticated remote attacker with administrator credentials to execute arbitrary commands with root privileges. The vulnerability exists in AsyncOS Software version 10.0 and later.

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 the AsyncOS versionAccess the appliance CLI and run the 'version' command, or log into the web interface and check System Administration > AsyncOS Software versionAffected if The displayed version matches any of: 10.0.0-233, 10.0_base, 10.1.0, 10.1.0-204, 10.1.1-230, 10.1.1-234, 10.5.0, 10.5.0-358, 11.0.0, 11.0.0-613, or 11.0.0-641 (or falls within the 10.0.x to 11.0.x range without having applied the fixed releases)
-
Confirm the web interface is enabledIn the CLI, run 'interfaceconfig' or check through the web interface under Network > IP Interfaces to verify the HTTP/HTTPS management interface is activeAffected if The web interface (HTTP or HTTPS) is enabled and accessible on any management interface
-
Verify administrator account exposureCheck the appliance's administrative access settings: in the CLI run 'ipaccess' or through the web interface under System Administration > Administrative Users > Access SettingsAffected if Administrative access is permitted from untrusted networks or the web interface is exposed to the internet or wide-area networks
You are affected if your Cisco Web Security Appliance runs any AsyncOS version between 10.0 and 11.0.0-641, has the web interface enabled, and administrative access is possible from your network.

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 dataUpgrade Cisco AsyncOS Software to fixed release 10.5.1-270 or 10.1.1-235. Restrict administrative access to trusted networks and enforce strong credential policies.
