CVE-2020-7832
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 DEXT5 Upload solution allows an unauthenticated attacker to download and execute an arbitrary file via AddUploadFile, SetSelectItem, DoOpenFile function.(CVE-2020-7832)
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 confidenceImproper input validation vulnerability in the DEXT5 Upload solution allows unauthenticated remote attackers to download and execute arbitrary files via the AddUploadFile, SetSelectItem, and DoOpenFile functions. The lack of proper input sanitization enables complete file 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.
-
Identify DEXT5 installationSearch the system for DEXT5 Upload components, typically found in web application directories or as part of content management systems. Look for files named dext5.* or dext5upload.*Affected if DEXT5 software is present on the system
-
Determine installed DEXT5 versionLocate the version information file or check the assembly/dll version if DEXT5 is deployed as a component. Common locations include the dext5 installation directory or within the application's bin folder.Affected if The installed version is 5.0.0.117 or lower
-
Verify upload functionality is enabledCheck if the DEXT5 upload module is actively enabled in the web application configuration or deployed as part of the running website. Confirm the upload endpoint is accessible.Affected if The upload functionality is enabled and exposed
-
Check network accessibility of upload componentDetermine if the DEXT5 upload handler (typically at paths like /dext5upload/ or /upload/dext5*) is reachable from unauthenticated network connections.Affected if The upload component is accessible without authentication
-
Inspect for vulnerable function exposureReview web application logs or network traffic to see if the AddUploadFile, SetSelectItem, or DoOpenFile functions are being called. These may appear as POST parameters or API endpoints.Affected if Any of these functions are exposed and callable without authentication
The environment is affected if DEXT5 version 5.0.0.117 or lower is installed with the upload functionality enabled and accessible to unauthenticated users.

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 dataApply vendor patches immediately; if no patch available, restrict network access to the upload component or disable it until remediation is possible. Validate that file upload functionality is restricted to authenticated, authorized users only.
