CVE-2019-25240
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 · uneditedRifatron 5brid DVR contains an unauthenticated vulnerability in the animate.cgi script that allows unauthorized access to live video streams. Attackers can exploit the Mobile Web Viewer module by specifying channel numbers to retrieve sequential video snapshots without authentication.
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 confidenceRifatron 5brid DVR contains an unauthenticated access vulnerability in the animate.cgi script within its Mobile Web Viewer module. Attackers can retrieve sequential video snapshots from specific camera channels without any authentication by manipulating channel number parameters.

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 the DVR device modelAccess the device administration interface or check device documentation to confirm the model is Rifatron 5brid DVRAffected if The device is a Rifatron 5brid DVR system
-
Verify Mobile Web Viewer module is accessibleAttempt to access the Mobile Web Viewer web interface (typically available on the same IP as the DVR admin panel, often on port 8080 or 81, or under paths like /mobile, /mobilelite, or /webviewer)Affected if Mobile Web Viewer module is exposed and accessible on the network
-
Confirm animate.cgi endpoint existsMake a direct HTTP request to the animate.cgi script within the Mobile Web Viewer path (for example, accessing a URL pattern like http://[DVR-IP]:[PORT]/cgi-bin/animate.cgi or similar path under the Mobile Web Viewer)Affected if The animate.cgi script responds to HTTP requests
-
Test unauthenticated parameter manipulationSend an HTTP request to the animate.cgi endpoint with different channel number parameter values (such as ?channel=1, ?channel=2, etc.) without providing any authentication credentialsAffected if The script returns sequential video snapshots or image data without requiring authentication
A user is affected if they operate a Rifatron 5brid DVR with the Mobile Web Viewer enabled and the animate.cgi endpoint accessible without any authentication, allowing unauthorized video snapshot retrieval via parameter manipulation.

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 dataRestrict external network access to the DVR system; implement proper authentication and authorization controls on the animate.cgi endpoint; contact vendor for firmware patch.
