CVE-2021-32530
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 · uneditedOS command injection vulnerability in Array function in QSAN XEVO allows remote unauthenticated attackers to execute arbitrary commands via status parameter. The referred vulnerability has been solved with the updated version of QSAN XEVO v2.1.0.
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.
dbcve analysis · high confidenceOS command injection vulnerability in the Array function of QSAN XEVO allows remote unauthenticated attackers to execute arbitrary operating system commands through the status parameter. This is a classic command injection flaw where user-supplied input in the status parameter is passed unsafely to system shell commands.

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.
-
Confirm QSAN XEVO is installedAccess the device management interface or check system information to identify if QSAN XEVO software is running. Look for the QSAN product web interface or check running services on the device.Affected if QSAN XEVO software is present on the system
-
Check the installed XEVO versionNavigate to the QSAN XEVO web interface, typically at the device IP address. Locate the version information in the system settings, about page, or firmware information section. Alternatively, check the firmware package installed on the device.Affected if The installed version is 1.2.0 or any version lower than 1.2.0
-
Verify the Array function is accessibleSend an HTTP request to the XEVO web interface targeting the Array function endpoint. This is typically found in the web application path, such as /cgi-bin/xe/array or similar. Inspect the response to confirm the endpoint exists and responds.Affected if The Array function endpoint responds to HTTP requests, indicating it is enabled and accessible
-
Confirm the status parameter accepts inputSend a crafted HTTP GET or POST request to the Array function with a test value in the status parameter (e.g., status=test). Observe whether the parameter is processed and reflected in the response or used in backend operations.Affected if The status parameter is accepted and processed by the application without proper input validation
-
Check if the web interface is exposed to untrusted networksReview network configuration to determine if the QSAN XEVO management interface (typically ports 80/443 or custom HTTP/HTTPS ports) is accessible from external networks or the internet. Check firewall rules and network segmentation settings.Affected if The QSAN XEVO web interface is reachable from untrusted or external networks without network-level restrictions
A user is affected if QSAN XEVO version 1.2.0 or lower is installed, the Array function with the status parameter is accessible, and the management interface is exposed to the network where the vulnerability can be triggered.

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 · scopedUpdate QSAN XEVO to version v2.1.0 or later to patch the vulnerability. Prior to updating, isolate the device from untrusted networks since it is exploitable remotely without authentication.
QSAN XEVO v2.1.0
- Obtain QSAN XEVO v2.1.0 from the official QSAN website or trusted distribution channel
- Follow QSAN's official upgrade procedure to update from version 1.2.0 or earlier to v2.1.0
- Verify the upgrade was successful by checking the software version
