CVE-2024-1817
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 has been found in Demososo DM Enterprise Website Building System up to 2022.8 and classified as critical. Affected by this vulnerability is the function dmlogin of the file indexDM_load.php of the component Cookie Handler. The manipulation of the argument is_admin with the input y leads to improper authentication. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-254605 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceThe Demososo DM Enterprise Website Building System (versions up to 2022.8) contains an authentication bypass vulnerability in the Cookie Handler component. The dmlogin function in indexDM_load.php improperly validates the is_admin cookie parameter, allowing attackers to set is_admin=y to bypass authentication and gain administrative access. This is a critical remote authentication bypass with CVSS 9.8.

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.
-
Confirm Demososo DM Enterprise installationSearch for Demososo DM files or check website footers/readme files for 'Demososo' or 'DM Enterprise Website Building System' brandingAffected if The software is present on the server
-
Identify installed versionLocate version information in configuration files, readme files, or the CMS admin panel. Compare against the affected range: 2022.0 through 2022.8Affected if The installed version is 2022.0, 2022.1, 2022.2, 2022.3, 2022.4, 2022.5, 2022.6, 2022.7, or 2022.8
-
Locate vulnerable fileSearch for indexDM_load.php in the web root or admin directories. This file contains the dmlogin function that handles authenticationAffected if The file exists and is accessible via web request
-
Check cookie handler implementationExamine indexDM_load.php for the is_admin cookie parameter validation logic. Look for code that reads the is_admin cookie value without proper server-side verificationAffected if The is_admin cookie is read and trusted without server-side validation before granting access
A user is affected if Demososo DM Enterprise Website Building System version 2022.0 through 2022.8 is installed and the indexDM_load.php file with the vulnerable is_admin cookie handler is present and accessible.

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 dataSince the vendor did not respond to disclosure and no patch exists, organizations should deploy a WAF rule to block cookie manipulation of the is_admin parameter, implement additional server-side session validation, and consider migrating to an actively maintained CMS if the vendor remains unresponsive.
