CVE-2020-16245
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 · uneditedAdvantech iView, Versions 5.7 and prior. The affected product is vulnerable to path traversal vulnerabilities that could allow an attacker to create/download arbitrary files, limit system availability, and remotely execute 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 confidenceAdvantech iView versions 5.7 and prior contain path traversal vulnerabilities that allow attackers to create or download arbitrary files on the system, potentially leading to system unavailability and remote code execution.

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 installed Advantech iView versionLocate the iView application and check its version information, typically found in the application GUI under 'About' or in installation/configuration filesAffected if Version is 5.7 or lower (any version <= 5.7)
-
Confirm web interface accessibilityDetermine if the iView web management interface is accessible on the network (common ports 8080, 8443, or configured HTTP/HTTPS ports)Affected if Web interface is exposed and version is <= 5.7
-
Locate file operation endpointsReview application documentation or enumerate web service endpoints related to file download, upload, or export functionalityAffected if File operation endpoints exist and version is <= 5.7
-
Check for path traversal protectionInspect application configuration files or test file operation endpoints with path traversal sequences (such as ../../) in file path parametersAffected if Path traversal sequences are not properly validated or blocked, and version is <= 5.7
-
Verify file access controlsExamine configuration or access control settings for file operations to determine if arbitrary file paths can be specifiedAffected if Application allows unrestricted file path input in file operations, and version is <= 5.7
If Advantech iView version 5.7 or prior is installed and the application contains accessible file operation features, the environment is vulnerable to path traversal exploitation.

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 to a version beyond 5.7 that includes proper path traversal protections; implement strict input validation and file access controls on all file operations.
