CVE-2024-4739
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 · uneditedThe lack of access restriction to a resource from unauthorized users makes MXsecurity software versions v1.1.0 and prior vulnerable. By acquiring a valid authenticator, an attacker can pose as an authorized user and successfully access the resource.
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 confidenceMXsecurity software versions v1.1.0 and prior lacks proper access restrictions on certain resources, allowing an attacker who has obtained a valid authenticator to impersonate an authorized user and access resources they should not have permission to access. This appears to be an authorization bypass vulnerability where proper access control checks are missing or insufficient.

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 Moxa Mxsecurity installationLocate the Mxsecurity software on the system. Check common installation directories or use system commands to list installed software packages named 'Mxsecurity' or 'moxa' related security tools.Affected if Mxsecurity software is found on the system
-
Determine installed versionCheck the installed version of Moxa Mxsecurity. Use package management commands, check the software's about/diagnostics page, or examine version files in the installation directory.Affected if The installed version is 1.1.0 or any version prior to 1.1.0
-
Review access control configurationExamine the access control settings, user permissions, and role configurations within the Mxsecurity administrative interface or configuration files.Affected if Any user with valid authentication can access resources outside their assigned permissions or roles are not properly enforced
-
Audit resource access permissionsTest or audit whether authenticated users can reach resources (APIs, files, functions) that should be restricted based on their assigned role or permission level.Affected if Users can access resources they should not have permission to access based on their defined role
-
Check for unauthorized access logsReview authentication and access logs for instances where users accessed resources outside their normal permission scope or where access control checks may have been bypassed.Affected if Logs show users accessing resources inconsistent with their assigned permissions
A system is affected if Moxa Mxsecurity version 1.1.0 or earlier is installed and authenticated users can access resources beyond their authorized permissions.

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 on all sensitive resources to ensure authenticated users can only access resources they are explicitly permitted to access. Consider updating to a patched version if available and conducting a security review of all access control logic.
