CVE-2013-3586
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 · uneditedSamsung Web Viewer for Samsung DVR devices allows remote attackers to bypass authentication via an arbitrary SessionID value in a cookie.
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 confidenceSamsung Web Viewer for Samsung DVR devices contains an authentication bypass vulnerability where the application validates the presence of a SessionID cookie but fails to properly verify its authenticity or validity. Attackers can bypass authentication by simply setting an arbitrary SessionID value in the cookie, gaining unauthorized access to the DVR system's web interface.

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 Samsung DVR web service exposureScan network for open HTTP/HTTPS ports on DVR devices, typically ports 80, 443, 8080, or 8443. Identify device by examining HTTP response headers or login page for Samsung DVR/Smart Viewer branding.Affected if Samsung DVR web interface is accessible on the network
-
Confirm Samsung Smart Viewer is in useAccess the web interface and examine the page source, URL patterns, or error messages for 'Samsung Smart Viewer', 'Samsung DVR', or Samsung-specific login forms.Affected if The web interface is Samsung Smart Viewer or Samsung DVR web interface
-
Test authentication bypass with arbitrary SessionIDUse a web browser or tool like curl to access a protected page (such as the main monitoring view or settings) while setting a custom SessionID cookie (e.g., SessionID=anything) without providing valid credentials.Affected if Access is granted to protected areas using only a fabricated SessionID cookie value
-
Verify cookie validation behaviorInspect the authentication flow by capturing network traffic. Attempt to access protected endpoints with no SessionID cookie, then with a random SessionID value, and compare the responses.Affected if Both requests result in access or the random SessionID is accepted without verification
A user is affected if their Samsung DVR or Smart Viewer web interface can be accessed using only an arbitrary SessionID cookie value without valid 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 dataApply vendor patches for Samsung DVR firmware. If no patch available, restrict network access to the web interface via firewall rules or disable remote web access until a fix is released.
