CVE-2021-1560
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 · uneditedMultiple vulnerabilities in Cisco DNA Spaces Connector could allow an authenticated, remote attacker to perform a command injection attack on an affected device. These vulnerabilities are due to insufficient input sanitization when executing affected commands. A high-privileged attacker could exploit these vulnerabilities on a Cisco DNA Spaces Connector by injecting crafted input during command execution. A successful exploit could allow the attacker to execute arbitrary commands as root within the Connector docker container.
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 confidenceCommand injection vulnerabilities in Cisco DNA Spaces Connector allow an authenticated, high-privileged attacker to inject malicious commands through insufficient input sanitization. Successful exploitation grants root-level command execution within the Connector's Docker container.

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 Cisco DNA Spaces Connector installationLocate the Cisco DNA Spaces Connector software on the system. Check for installation directories, running processes, or Docker containers related to 'dna spaces' or 'cisco dna spaces'. Use commands like 'docker ps' or search for known installation paths.Affected if The software is present and the version is below 2.0.519
-
Determine installed versionAccess the Connector's administrative interface or check the software version through its CLI if available. Compare the version number to the affected range (anything below 2.0.519).Affected if The installed version is lower than 2.0.519
-
Verify Docker container environmentConfirm that the Connector runs within a Docker container. Use 'docker ps' or 'docker inspect' to identify containers associated with Cisco DNA Spaces. The vulnerability exists specifically within the Connector's Docker container.Affected if DNA Spaces Connector is running inside a Docker container and the version is below 2.0.519
-
Check for high-privileged user accessReview authentication logs and user privilege configurations for the DNA Spaces Connector administrative interface. Identify accounts with high-privileged or administrative access, as the attacker requires authenticated high-privileged credentials.Affected if Untrusted or compromised accounts have high-privileged access to the Connector interface
The environment is affected if Cisco DNA Spaces Connector is installed with a version below 2.0.519 and runs in a Docker container accessible to authenticated high-privileged 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 data2.0.519
Apply vendor-provided patches when available. Until then, restrict access to trusted users only and monitor for suspicious command activity within the Docker container environment.
