CVE-2026-8402
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 · uneditedImproper neutralization of special elements used in an SQL command ('SQL injection') vulnerability in Eksagate Electronic Engineering and Computer Industry Trade Inc. SYSGUARD 6001 allows Blind SQL Injection. This issue affects SYSGUARD 6001: from 2.0.2 before 6.1.16.0. NOTE: The vendor was contacted and it was learned that the product is not supported.
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 confidenceSYSGUARD 6001 versions 2.0.2 through 6.1.16.0 contain a blind SQL injection vulnerability in how the application handles special elements in SQL commands. This allows unauthenticated remote attackers to inject malicious SQL queries, potentially extracting sensitive data from the backend database or compromising the system. The CVSS 9.8 score indicates trivial network exploitation with complete impact on confidentiality, integrity, and availability.

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 Eksagate SYSGUARD 6001 installationLocate the SYSGUARD application on the system. Check for processes named 'sysguard', 'eksagate', or related service names. Review running services or installed applications list for 'SYSGUARD' or 'Eksagate' product entries.Affected if The system runs Eksagate SYSGUARD 6001 software
-
Determine SYSGUARD versionCheck the installed version of SYSGUARD 6001. Common methods include: reviewing the software's about dialog, checking installed program metadata, examining version files in the installation directory, or querying the application via its built-in version command or API endpoint.Affected if The installed version is 2.0.2 or higher but lower than 6.1.16.0
-
Identify exposed web interface or APIReview network configuration to determine if SYSGUARD's web interface or API endpoints are accessible over the network. Check for open ports typically used by SYSGUARD (consult product documentation for default ports). Use network scanning tools to identify exposed HTTP/HTTPS services responding for SYSGUARD.Affected if The SYSGUARD web interface or API is accessible from network locations where untrusted input could be submitted
-
Check for unsanitized input handlingExamine the application logs or network traffic for unusual query patterns in SQL-style syntax that might indicate SQL injection testing or exploitation attempts. Review any available audit logs for failed authentication or query error messages.Affected if Application accepts user input through web forms, API parameters, or URL arguments without documented input validation or parameterized query usage
-
Verify database access controlsReview database user permissions for the SYSGUARD application database account. Determine if the database user has elevated privileges (such as db_owner, superuser, or administrative roles) that could allow arbitrary SQL execution.Affected if The application database account has excessive privileges beyond what is required for its documented functionality
The system is affected if it runs Eksagate SYSGUARD 6001 version 2.0.2 through less than 6.1.16.0 and has the vulnerable web interface or API exposed to network input.

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.
dbcve · scopedSince the vendor has confirmed the product is not supported and no patch is available, organizations should immediately assess whether upgrading to 6.1.16.0 is possible, implement a WAF with SQL injection rules in front of the application, or evaluate replacing the product with a supported alternative.
- This vulnerability has no remediation path available.
- The vendor (Eksagate Electronic Engineering and Computer Industry Trade Inc.) has explicitly stated that SYSGUARD 6001 is not a supported product.
- Consider migrating to an actively supported security monitoring solution from a vendor that provides security patches.
- If continued use of SYSGUARD 6001 is unavoidable, implement network-level segmentation to limit exposure to the affected system.
- Place the SYSGUARD 6001 device behind a firewall with strict ingress/egress rules to reduce attack surface.
- Monitor network traffic for indicators of SQL injection attempts targeting the device.
