CVE-2020-10513
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 · uneditedThe file management interface of iCatch DVR firmware before 20200103 contains broken access control which allows the attacker to remotely manipulate arbitrary file.
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 confidenceThe iCatch DVR firmware before version 20200103 has a broken access control vulnerability in its file management interface. This allows unauthenticated or improperly authenticated remote attackers to manipulate arbitrary files on the device through the web interface or API. The vulnerability stems from insufficient authorization checks before file operations.

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 firmware versionAccess the DVR administrative interface or check system information page to retrieve the current firmware version numberAffected if The displayed version is less than 20200103
-
Verify file management interface accessibilityAttempt to access the file management or file operation endpoints on the DVR web interface without credentialsAffected if The interface allows access or returns valid responses without requiring authentication
-
Test authorization on file operationsUse the API or web interface to attempt a file read, write, or delete operation with invalid or absent session credentialsAffected if The operations complete successfully without proper authorization validation
-
Inspect access logs for unauthorized file operationsReview DVR system logs or web server access logs for file operation requests originating from unauthenticated or unauthorized IP addressesAffected if Logs show file manipulation attempts that succeeded without valid authentication tokens
-
Confirm firmware version is below thresholdCompare your confirmed firmware version against the vulnerable range: any build earlier than 20200103Affected if The installed version number is below 20200103 and the file management interface is network-accessible
You are affected if your iCatch DVR firmware version is below 20200103 AND the file management interface is exposed on your network, particularly if unauthenticated file operations succeed or unauthorized access attempts appear in logs.

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 data20200103
Update iCatch DVR firmware to version 20200103 or later, which contains proper access control validation. If updates are unavailable, restrict network access to the DVR management interface and monitor for unauthorized file access attempts.
