CVE-2020-7865
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 vulnerability(improper input validation) in the ExECM CoreB2B solution allows an unauthenticated attacker to download and execute an arbitrary file via httpDownload function. A successful exploit could allow the attacker to hijack vulnerable system.
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 confidenceThis is an improper input validation vulnerability in ExECM CoreB2B's httpDownload function. An unauthenticated attacker can exploit this flaw to download and execute arbitrary files on the vulnerable system, achieving remote code execution and complete system compromise.

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 ExECM CoreB2B installationLocate the Inoguard Execm Coreb2b application on the system, typically found in the installation directory or running as a service. Identify the executable or service name associated with this product.Affected if The product is present on the system
-
Determine installed versionCheck the version of the installed ExECM CoreB2B software. Look for version information in the application metadata, about dialog, or version file within the installation directory.Affected if The installed version is 1.1.0.4 or earlier
-
Verify httpDownload function exposureIdentify if the httpDownload function is exposed via web interface or API endpoint. Check the application's web configuration or exposed service endpoints to determine if this function is accessible over HTTP/HTTPS.Affected if The httpDownload endpoint is externally accessible or enabled
-
Assess authentication enforcement on httpDownloadExamine the application's configuration and access controls to verify whether the httpDownload function enforces authentication. Test if the endpoint can be accessed without credentials.Affected if The httpDownload function can be accessed without authentication
A system is affected if Inoguard Execm CoreB2B version 1.1.0.4 or earlier is installed with the httpDownload function exposed and accessible without authentication.

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 authentication checks on the httpDownload function to ensure only authorized, validated file requests are processed. Consider restricting file types and paths accessible through this function.
