CVE-2025-47697
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 · uneditedClient-side enforcement of server-side security issue exists in wivia 5 all versions. If exploited, an unauthenticated attacker may bypass authentication and operate the affected device as the moderator user.
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 confidenceThis is an authentication bypass vulnerability in wivia 5 where client-side enforcement of server-side security allows an unauthenticated attacker to bypass authentication and operate the device with moderator privileges. The vulnerability stems from the application trusting client-side security controls or tokens instead of properly validating them server-side.

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 Wivia 5 installationIdentify if the system is running Uchida Wivia 5 by checking the firmware version, application logs, or network service banners. Look for 'wivia' or 'Wivia 5' in running processes, installed packages, or device information.Affected if The system is running any version of Uchida Wivia 5 firmware.
-
Identify authentication mechanismExamine the web application or API configuration files for Wivia 5. Look for authentication-related settings, particularly any configuration that specifies 'client-side', 'client enforce', or token-based session management where tokens originate from the client.Affected if The application uses client-side security controls, tokens, or session identifiers that are not validated server-side.
-
Check moderator privilege configurationReview the user privilege configuration or role-based access control (RBAC) settings in Wivia 5. Identify how moderator privileges are defined and whether client-supplied parameters determine privilege levels.Affected if Moderator privileges can be assigned or escalated through client-supplied parameters without server-side verification.
-
Test unauthenticated moderator accessSend an HTTP request to Wivia 5 endpoints with a crafted request claiming moderator privileges, but without completing server-side authentication. Observe if the application accepts client-side claims for moderator access.Affected if The application grants moderator-level access based on client-side claims without proper server-side authentication validation.
A user is affected if the system runs Uchida Wivia 5 and the application trusts client-side security controls or tokens for authentication and privilege assignment instead of validating them server-side.

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 any available vendor patch for wivia 5 that addresses client-side security enforcement. If no patch exists, implement server-side authentication validation and disable client-side trust mechanisms.
