CVE-2023-44413
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 · uneditedD-Link D-View shutdown_coreserver Missing Authentication Denial-of-Service Vulnerability. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of D-Link D-View. Authentication is not required to exploit this vulnerability. The specific flaw exists within the shutdown_coreserver action. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-19572.
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 confidenceD-Link D-View contains a missing authentication vulnerability in the shutdown_coreserver action. Remote attackers can invoke this endpoint without any authentication credentials, causing the core server to shut down and resulting in a denial-of-service condition. The vulnerability stems from the lack of authentication checks before executing the shutdown functionality.

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 D-Link D-View installationCheck if D-Link D-View 8 is installed on the system. Look for the application in installed programs or check the D-View service status.Affected if D-Link D-View 8 version 1.0.2.13 is installed
-
Verify the exact version numberAccess the D-View administrative interface or check the installed software version information. Compare the installed version against 1.0.2.13.Affected if Installed version is exactly 1.0.2.13
-
Confirm the shutdown_coreserver endpoint is accessibleAttempt to access the shutdown_coreserver endpoint via HTTP/HTTPS request without providing any authentication credentials. Check if the endpoint responds to unauthenticated requests.Affected if The endpoint responds to unauthenticated requests and accepts the shutdown command
-
Check if core server shuts down without credentialsSend a request to the shutdown_coreserver action without any authentication headers or session tokens. Observe if the core server shuts down or returns a success response.Affected if The server shuts down or returns success without requiring authentication
The environment is affected if D-Link D-View 8 version 1.0.2.13 is running and the shutdown_coreserver endpoint accepts unauthenticated requests, allowing remote attackers to shut down the core server.

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 proper authentication and authorization checks on the shutdown_coreserver endpoint to ensure only authorized users can execute this action. If available, apply vendor patches from D-Link. Consider network segmentation to limit exposure to unauthenticated attackers.
