CVE-2024-3785
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 · uneditedVulnerability in WBSAirback 21.02.04, which involves improper neutralisation of Server-Side Includes (SSI), through Device NAS shared section (/admin/DeviceNAS). Exploitation of this vulnerability could allow a remote user to execute arbitrary code.
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 confidenceWBSAirback version 21.02.04 contains an SSI (Server-Side Include) injection vulnerability in the Device NAS shared section (/admin/DeviceNAS). This improper neutralization of user input allows attackers to inject malicious SSI directives that the web server will parse and execute, potentially leading to remote code execution on the affected system.

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 WBSAirback versionLocate the installed WBSAirback version through the web administration interface, configuration files, or system inventory tools. Check version display in the product UI or examine version-related files in the application directory.Affected if The installed version is exactly 21.02.04
-
Verify /admin/DeviceNAS endpoint existsAttempt to access the URI path /admin/DeviceNAS on the web server hosting WBSAirback. This can be done via HTTP request or by examining the web server's routing configuration for this application.Affected if The endpoint responds and accepts user input in the Device NAS configuration section
-
Confirm SSI processing is enabledExamine the web server configuration (Apache, nginx, or embedded server used by WBSAirback) to determine if Server-Side Include parsing is enabled for the application. Look for SSI-related directives or module加载 configurations.Affected if SSI parsing is enabled and the application processes .shtml or executes SSI directives in the application context
-
Test for SSI injection pointSubmit a benign SSI directive such as <!--#echo var="DATE_LOCAL" --> through the DeviceNAS form parameters and observe whether the server parses and returns the executed directive output.Affected if The submitted SSI directive is parsed and its output is reflected in the response, confirming the injection vulnerability
You are affected if WBSAirback version 21.02.04 is installed, the /admin/DeviceNAS endpoint is accessible, and SSI processing is enabled on the web server, allowing injected SSI directives to be executed.

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 dataImplement strict input validation and output encoding on all user-supplied data in the /admin/DeviceNAS endpoint to neutralize SSI directives. Alternatively, disable SSI parsing in the web server configuration for this application.
