CVE-2023-35851
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 · uneditedSUNNET WMPro portal's FAQ function has insufficient validation for user input. An unauthenticated remote attacker can inject arbitrary SQL commands to obtain sensitive information via a database.
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 confidenceSQL injection vulnerability in the FAQ function of SUNNET WMPro portal allows unauthenticated remote attackers to inject arbitrary SQL commands through user input that lacks proper validation, enabling extraction of sensitive data from the database.

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 Sun.net Wmpro is installedLocate the application installation directory or check system inventory for 'Wmpro' or 'SUNNET WMPro' software. Look for executable files, web application files, or service entries named 'wmpro' or containing 'sun.net'.Affected if The product Sun.net Wmpro is present on the system
-
Verify the installed version is 5.0Check version information in application files, About dialog, or configuration files. Common locations: installation folder readme/version files, web.config (if web app), registry entries, or startup banner when launching the application.Affected if The installed version is exactly 5.0 (version range is single point)
-
Determine if FAQ module is enabledCheck if the FAQ function is accessible within the WMPro portal. This may require logging into the application and navigating to FAQ-related menu items, or checking the application's module configuration files.Affected if FAQ module is present and accessible to users
-
Inspect FAQ function for user input handlingLocate the FAQ functionality code or configuration. Examine how user input is processed in the FAQ feature - look for query parameters, form fields, or API endpoints that accept user-supplied data related to FAQ viewing or searching.Affected if The FAQ function accepts user input without visible sanitization or validation parameters in the request
-
Check for SQL injection protection in FAQ codeIf source code or decompiled binaries are available, examine the FAQ function handler. Look for SQL query construction that uses user input directly, versus parameterized queries or input validation routines.Affected if User input in FAQ function appears to be concatenated directly into SQL queries without prepared statements or validation
The environment is affected if Sun.net Wmpro version 5.0 is installed and the FAQ module is accessible without the vulnerability being patched.

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 parameterized queries (prepared statements) or proper input validation/sanitization in the FAQ function to prevent SQL injection, and conduct thorough security testing to verify the fix.
