CVE-2020-7480
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 CWE-94: Improper Control of Generation of Code ('Code Injection') vulnerability exists in Andover Continuum (All versions), which could cause files on the application server filesystem to be viewable when an attacker interferes with an application's processing of XML data.
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 confidenceA CWE-94 Code Injection vulnerability in Andover Continuum (all versions) allows attackers to view files on the application server filesystem through manipulation of XML data processing. The improper control of code generation during XML parsing enables unauthenticated file disclosure with critical severity (CVSS 9.8).

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 Andover Continuum installationIdentify if Schneider Electric Andover Continuum software is installed on the system by checking for the application directory, service, or web server process typically running on port 80/443Affected if Andover Continuum software or web interface is found on the host
-
Identify the Andover Continuum modelCheck the system inventory, firmware information, or web interface banner for the specific model number (9680, 5740, 5720, Bcx4040, Bcx9640, 9900, 9940, or 9941)Affected if The model matches any of the affected variants listed in the CVE
-
Verify XML processing endpoint is exposedCheck if the web interface XML handler is accessible by attempting to access common XML processing paths or reviewing web server configuration for XML parsing endpointsAffected if XML data processing functionality is accessible via the web interface
-
Confirm network exposure of the web interfaceDetermine if the Andover Continuum web server is reachable from the network by checking firewall rules, listening ports, and interface bindings (0.0.0.0 vs 127.0.0.1)Affected if The web interface is accessible from network segments beyond localhost
Any Andover Continuum system (any of the eight listed models) with an exposed web interface containing XML processing functionality is vulnerable, since all firmware versions are affected.

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 dataSince all versions are affected, contact the vendor for an available patch. Implement strict input validation and sanitization on XML data processing pathways, and restrict XML parser permissions to minimize filesystem access exposure.
