CVE-2025-3003
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, which was classified as critical, was found in ESAFENET CDG 3. Affected is an unknown function of the file /CDGServer3/UserAjax. The manipulation of the argument Username leads to sql injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. 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.

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 ESAFENET CDG 3 installationSearch for CDG 3 related processes, services, or web applications running on the server. Check for CDGServer3 in running services or installed software listings.Affected if ESAFENET CDG 3 is installed and running on the system
-
Verify UserAjax endpoint accessibilityAttempt to access the /CDGServer3/UserAjax endpoint via HTTP/HTTPS request to determine if the web interface is exposed. Check if the endpoint responds to requests.Affected if The /CDGServer3/UserAjax endpoint is accessible over the network
-
Test Username parameter for SQL injectionSend a crafted request to the UserAjax endpoint with the Username parameter set to a SQL injection test payload (such as a single quote or boolean-based test). Observe the application response for SQL error messages or unexpected behavior.Affected if The Username parameter accepts input and the application processes it without proper sanitization, leading to SQL errors or anomalous behavior
-
Review application logs for SQL injection indicatorsExamine web server logs, application logs, and database logs for patterns indicating SQL injection attempts against the UserAjax endpoint. Look for SQL syntax in Username parameter values.Affected if Logs show SQL injection attempts or successful exploitation signatures in the Username parameter
-
Check database for unauthorized data access or manipulationReview database audit logs or query the database directly to check for unauthorized data access, privilege escalation, or data modification that correlates with UserAjax endpoint usage.Affected if Database shows unauthorized queries or modifications originating from the UserAjax endpoint
A user is affected if ESAFENET CDG 3 is running and the /CDGServer3/UserAjax endpoint is accessible with the Username parameter vulnerable to SQL injection.

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) for all database interactions involving user input. Until an official vendor patch is available, consider web application firewall (WAF) rules to block SQL injection patterns in the Username parameter.
