CVE-2025-23440
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 · uneditedMissing Authorization vulnerability in radicaldesigns radSLIDE radslide allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects radSLIDE: from n/a through <= 2.1.
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 confidenceMissing Authorization vulnerability in radSLIDE allows attackers to exploit incorrectly configured access control security levels. This means the application fails to properly verify user permissions before allowing access to certain resources or functionality, potentially allowing unauthorized users to perform actions they shouldn't be able to.

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.
-
Locate radSLIDE installationSearch the system for radSLIDE executables, libraries, or application files. Check common installation directories and the application codebase for radSLIDE components.Affected if radSLIDE is found installed in the environment and uses configurable access control security levels that may be misconfigured.
-
Identify access control configuration filesLocate configuration files that define access control policies, security levels, or permission settings within the radSLIDE application directory.Affected if Access control configuration files exist and contain security level settings that could be improperly configured.
-
Review security level settingsExamine the access control configuration files to identify security level definitions and verify if proper authorization enforcement is enabled for all protected resources.Affected if Security levels are defined but authorization checks are not consistently enforced across all resources or actions.
-
Test authorization enforcementAttempt to access protected resources or functionalities with different user privilege levels to verify that permission checks are actually performed before granting access.Affected if Access is granted to protected resources without proper authorization verification, indicating the vulnerability is present.
The environment is affected if radSLIDE is installed and access control security levels are configured such that authorization checks are not properly enforced before granting access to sensitive resources or functionality.

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 authorization checks throughout the application to verify user permissions before granting access to sensitive resources or actions. Review and correct any misconfigured access control security levels.
